In 1773, private letters were published in which Massachusetts Governor Thomas Hutchinson claimed that the colonists could not enjoy all English liberties, and in which Lieutenant Governor Andrew Oliver called for the direct payment of colonial officials, which had been paid by local authorities. This would have reduced the influence of colonial representatives over their government. The letters' contents were used as evidence of a systematic plot against American rights, and discredited Hutchinson in the eyes of the people; the colonial Assembly petitioned for his recall. Benjamin Franklin, postmaster general for the colonies, acknowledged that he leaked the letters, which led to him being removed from his position. In Boston, Samuel Adams set about creating new Committees of Correspondence, which linked Patriots in all 13 colonies and eventually provided the framework for a rebel government. Virginia, the largest colony, set up its Committee of Correspondence in early 1773, on which Patrick Henry and Thomas Jefferson served. A total of about 7,000 to 8,000 Patriots served on these Committees; Loyalists were excluded. The committees became the leaders of the American resistance to British actions, and later largely determined the war effort at the state and local level. When the First Continental Congress decided to boycott British products, the colonial and local Committees took charge, examining merchant records and publishing the names of merchants who attempted to defy the boycott by importing British goods.
Meanwhile, Parliament passed the Tea Act lowering the price of taxed tea exported to the colonies, to help the British East India Company undersell smuggled untaxed Dutch tea. Special consignees were appointed to sell the tea to bypass colonial merchants. The act was opposed by those who resisted the taxes and also by smugglers who stood to lose business. In every colony demonstrators warned merchants not to bring in tea that included the hated new tax. In most instances, the consignees were forced by the Americans to resign and the tea was turned back, but Massachusetts governor Hutchinson refused to allow Boston merchants to give in to pressure. A town meeting in Boston determined that the tea would not be landed, and ignored a demand from the governor to disperse. On December 16, 1773, a group of men, led by Samuel Adams and dressed to evoke the appearance of Indigenous people, boarded the ships of the East India Company and dumped £10,000 worth of tea from their holds (approximately £636,000 in 2008) into Boston Harbor. Decades later, this event became known as the Boston Tea Party and remains a significant part of American patriotic lore. 1774–1775: Intolerable Acts.
The British government responded by passing four laws that came to be known as the Intolerable Acts, further darkening colonial opinion towards England. The first was the Massachusetts Government Act which altered the Massachusetts charter and restricted town meetings. The second was the Administration of Justice Act which ordered that all British soldiers to be tried were to be arraigned in Britain, not in the colonies. The third was the Boston Port Act, which closed the port of Boston until the British had been compensated for the tea lost in the Boston Tea Party. The fourth was the Quartering Act of 1774, which allowed royal governors to house British troops in the homes of citizens without permission of the owner. In response, Massachusetts patriots issued the Suffolk Resolves and formed an alternative shadow government known as the Provincial Congress, which began training militia outside British-occupied Boston. In September 1774, the First Continental Congress convened, consisting of representatives from each colony, to serve as a vehicle for deliberation and collective action. During secret debates, conservative Joseph Galloway proposed the creation of a colonial Parliament that would be able to approve or disapprove acts of the British Parliament, but his idea was tabled in a vote of 6 to 5 and was subsequently removed from the record. Congress called for a boycott beginning on December 1, 1774, of all British goods; it was enforced by new local committees authorized by the Congress.
It also began coordinating Patriot resistance by militias which existed in every colony and which had gained military experience in the French and Indian War. For the first time, the Patriots were armed and unified against Parliament. Military hostilities begin. King George declared Massachusetts to be in a state of rebellion in February 1775 and the British garrison received orders to seize the rebels' weapons and arrest their leaders, leading to the Battles of Lexington and Concord on April 19, 1775. The Patriots assembled a militia 15,000 strong and laid siege to Boston, occupied by 6500 British soldiers. The Second Continental Congress convened in Philadelphia on June 14, 1775. The congress was divided on the best course of action. They authorized formation of the Continental Army and appointed George Washington as its commander-in-chief, and produced the Olive Branch Petition in which they attempted to come to an accord with King George. The king, however, issued a Proclamation of Rebellion which declared that the states were "in rebellion" and the members of Congress were traitors. The Battle of Bunker Hill followed on June 17, 1775. It was a British victory—but at a great cost: about 1,000 British casualties from a garrison of about 6,000, as compared to 500 American casualties from a much larger force.
As Benjamin Franklin wrote to Joseph Priestley in October 1775: In the winter of 1775, the Americans invaded northeastern Quebec under generals Benedict Arnold and Richard Montgomery, expecting to rally sympathetic colonists there. The attack was a failure; many Americans were killed, captured, or died of smallpox. In March 1776, aided by the fortification of Dorchester Heights with cannons recently captured at Fort Ticonderoga, the Continental Army led by George Washington forced the British to evacuate Boston. The revolutionaries now fully controlled all thirteen colonies and were ready to declare independence. There still were many Loyalists, but they were no longer in control anywhere by July 1776, and all of the Royal officials had fled. Creating new state constitutions. Following the Battle of Bunker Hill in June 1775, the Patriots had control of Massachusetts outside Boston's city limits, and the Loyalists suddenly found themselves on the defensive with no protection from the British army. In each of the Thirteen Colonies, American patriots overthrew their existing governments, closed courts, and drove out British colonial officials. They held elected conventions and established their own legislatures, which existed outside any legal parameters established by the British. New constitutions were drawn up in each state to supersede royal charters. They proclaimed that they were now "states", no longer "colonies".
On January 5, 1776, New Hampshire ratified the first state constitution. In May 1776, Congress voted to suppress all forms of crown authority, to be replaced by locally created authority. New Jersey, South Carolina, and Virginia created their constitutions before July 4. Rhode Island and Connecticut simply took their existing royal charters and deleted all references to the crown. The new states were all committed to republicanism, with no inherited offices. On May 26, 1776, John Adams wrote James Sullivan from Philadelphia warning against extending the franchise too far: The resulting constitutions in states, including those of Delaware, Maryland, Massachusetts, New York, and Virginia featured: In Pennsylvania, New Jersey, and New Hampshire, the resulting constitutions embodied: The radical provisions of Pennsylvania's constitution lasted 14 years. In 1790, conservatives gained power in the state legislature, called a new constitutional convention, and rewrote the constitution. The new constitution substantially reduced universal male suffrage, gave the governor veto power and patronage appointment authority, and added an upper house with substantial wealth qualifications to the unicameral legislature. Thomas Paine called it a constitution unworthy of America.
Second Continental Congress. In April 1776, the North Carolina Provincial Congress issued the Halifax Resolves explicitly authorizing its delegates to vote for independence. By June, nine Provincial Congresses supported independence from Britain, and Pennsylvania, Delaware, Maryland, and New York followed. Richard Henry Lee was instructed by the Virginia legislature to propose independence, and he did so on June 7, 1776. Declaration of Independence. Gathered at Pennsylvania State House, later renamed Independence Hall, in Philadelphia, 56 of the nation's Founding Fathers, representing America's Thirteen Colonies, unanimously adopted and issued to King George III the Declaration of Independence, which was drafted largely by Thomas Jefferson and presented by the Committee of Five, which was charged with authoring it. The Congress struck several provisions of Jefferson's draft, and then adopted it unanimously on July 4. The Declaration embodied the political philosophies of liberalism and republicanism, rejected monarchy and aristocracy, and famously proclaimed that "all men are created equal". With the issuance of the Declaration of Independence, each colony began operating as independent and sovereign states. The next step was to form a union to facilitate international relations and alliances.
On November 5, 1777, the Congress approved the Articles of Confederation and Perpetual Union and sent it to each state for ratification. The Congress immediately began operating under the Articles' terms, providing a structure of shared sovereignty during prosecution of the Revolutionary War and facilitating international relations and alliances. The Articles were fully ratified on March 1, 1781. At that point, the Continental Congress was dissolved and a new government of the United States in Congress Assembled took its place the following day, on March 2, 1782, with Samuel Huntington leading the Congress as presiding officer. Defending the revolution. British return: 1776–1777. According to British historian Jeremy Black, the British had significant advantages, including a highly trained army, the world's largest navy, and an efficient system of public finance that could easily fund the war. However, they seriously misunderstood the depth of support for the American Patriot position, misinterpreting the situation as merely a large-scale riot. The British government believed that they could overawe the Americans by sending a large military and naval force:
In the Siege of Boston, Washington forced the British out of the city in the spring of 1776, and neither the British nor the Loyalists controlled any significant areas. The British, however, were amassing forces at their naval base at Halifax, Nova Scotia. They returned in force in July 1776, landing in New York and defeating Washington's Continental Army in August at the Battle of Brooklyn. This gave the British control of New York City and its strategic harbor. Following that victory, they requested a meeting with representatives from Congress to negotiate an end to hostilities. A delegation including John Adams and Benjamin Franklin met British admiral Richard Howe on Staten Island in New York Harbor on September 11 in what became known as the Staten Island Peace Conference. Howe demanded that the Americans retract the Declaration of Independence, which they refused to do, and negotiations ended. The British then seized New York City and nearly captured Washington's army. They made the city their main political and military base of operations, holding it until November 1783. The city became the destination for Loyalist refugees and a focal point of Washington's intelligence network.
The British also took New Jersey, pushing the Continental Army into Pennsylvania. Washington crossed the Delaware River back into New Jersey in a surprise attack in late December 1776 and defeated the Hessian and British armies at Trenton and Princeton, thereby regaining control of most of New Jersey. The victories gave an important boost to Patriots at a time when morale was flagging, and they have become iconic events of the war. In September 1777, in anticipation of a coordinated attack by the British Army on the revolutionary capital of Philadelphia, the Continental Congress was forced to depart Philadelphia temporarily for Baltimore, where they continued deliberations. In 1777, the British sent Burgoyne's invasion force from Canada south to New York to seal off New England. Their aim was to isolate New England, which the British perceived as the primary source of agitation. Rather than move north to support Burgoyne, the British army in New York City went to Philadelphia in a major case of mis-coordination, capturing it from Washington. The invasion army under Burgoyne was much too slow and became trapped in northern New York state. It surrendered after the Battles of Saratoga in October 1777. From early October 1777 until November 15, a siege distracted British troops at Fort Mifflin, Philadelphia, Pennsylvania, and allowed Washington time to preserve the Continental Army by safely leading his troops to harsh winter quarters at Valley Forge.
Prisoners. On August 23, 1775, George III declared Americans to be traitors to the Crown if they took up arms against royal authority. There were thousands of British and Hessian soldiers in American hands following their surrender at the Battles of Saratoga. Lord Germain took a hard line, but the British generals on American soil never held treason trials, and instead treated captured American soldiers as prisoners of war. The dilemma was that tens of thousands of Loyalists were under American control and American retaliation would have been easy. The British built much of their strategy around using these Loyalists. The British maltreated the prisoners whom they held, resulting in more deaths to American prisoners of war than from combat operations. At the end of the war, both sides released their surviving prisoners. American alliances after 1778. The capture of a British army at Saratoga encouraged the French to formally enter the war in support of Congress, and Benjamin Franklin negotiated a permanent military alliance in early 1778; France thus became the first foreign nation to officially recognize the Declaration of Independence. On February 6, 1778, the United States and France signed the Treaty of Amity and Commerce and the Treaty of Alliance. William Pitt spoke out in Parliament urging Britain to make peace in America and to unite with America against France, while British politicians who had sympathized with colonial grievances now turned against the Americans for allying with Britain's rival and enemy.
The Spanish and the Dutch became allies of the French in 1779 and 1780 respectively, forcing the British to fight a global war without major allies, and requiring it to slip through a combined blockade of the Atlantic. Britain began to view the American war for independence as merely one front in a wider war, and the British chose to withdraw troops from America to reinforce the British colonies in the Caribbean, which were under threat of Spanish or French invasion. British commander Sir Henry Clinton evacuated Philadelphia and returned to New York City. Washington intercepted him in the Battle of Monmouth Court House, the last major battle fought in the north. After an inconclusive engagement, the British retreated to New York City. The northern war subsequently became a stalemate, as the focus of attention shifted to the smaller southern theater. 1778–1783: the British move south. The British Royal Navy blockaded ports and held New York City for the duration of the war, and other cities for brief periods, but failed in their effort to destroy Washington's forces. The British strategy now concentrated on a campaign in the southern states. With fewer regular troops at their disposal, the British commanders saw the "southern strategy" as a more viable plan, as they perceived the south as strongly Loyalist with a large population of recent immigrants and large numbers of slaves who might be tempted to run away from their masters to join the British and gain their freedom.
Beginning in late December 1778, the British captured Savannah and controlled the Georgia coastline. In 1780, they launched a fresh invasion and took Charleston. A significant victory at the Battle of Camden meant that royal forces soon controlled most of Georgia and South Carolina. The British set up a network of forts inland, hoping that the Loyalists would rally to the flag. Not enough Loyalists turned out, however, and the British had to fight their way north into North Carolina and Virginia with a severely weakened army. Behind them, much of the territory that they had already captured dissolved into a chaotic guerrilla war, fought predominantly between bands of Loyalists and American militia, which negated many of the gains that the British had previously made. Surrender at Yorktown (1781). The British army under Cornwallis marched to Yorktown, Virginia, where they expected to be rescued by a British fleet. The fleet did arrive, but so did a larger French fleet. The French were victorious in the Battle of the Chesapeake, and the British fleet returned to New York for reinforcements, leaving Cornwallis trapped. In October 1781, the British surrendered their second invading army of the war under a siege by the combined French and Continental armies commanded by Washington.
End of the war. Washington did not know if or when the British might reopen hostilities after Yorktown. They still had 26,000 troops occupying New York City, Charleston, and Savannah, together with a powerful fleet. The French army and navy departed, so the Americans were on their own in 1782–83. The American treasury was empty, and the unpaid soldiers were growing restive, almost to the point of mutiny or possible coup d'etat. Washington dispelled the unrest among officers of the Newburgh Conspiracy in 1783, and Congress subsequently created the promise of a five years bonus for all officers. Historians continue to debate whether the odds were long or short for American victory. John E. Ferling says that the odds were so long that the American victory was "almost a miracle". On the other hand, Joseph Ellis says that the odds favored the Americans, and asks whether there ever was any realistic chance for the British to win. He argues that this opportunity came only once, in the summer of 1776, and Admiral Howe and his brother General Howe "missed several opportunities to destroy the Continental Army ... Chance, luck, and even the vagaries of the weather played crucial roles." Ellis's point is that the strategic and tactical decisions of the Howes were fatally flawed because they underestimated the challenges posed by the Patriots. Ellis concludes that, once the Howe brothers failed, the opportunity "would never come again" for a British victory.
Support for the conflict had never been strong in Britain, where many sympathized with the Americans, but now it reached a new low. King George wanted to fight on, but his supporters lost control of Parliament and they launched no further offensives in America on the eastern seaboard. Paris peace treaty. During negotiations in Paris, the American delegation discovered that France supported American independence but no territorial gains, hoping to confine the new nation to the area east of the Appalachian Mountains. The Americans opened direct secret negotiations with London, cutting out the French. British Prime Minister Lord Shelburne was in charge of the British negotiations, and he saw a chance to make the United States a valuable economic partner, facilitating trade and investment opportunities. The US obtained all the land east of the Mississippi River, including southern Canada, but Spain took control of Florida from the British. It gained fishing rights off Canadian coasts, and agreed to allow British merchants and Loyalists to recover their property. Prime Minister Shelburne foresaw highly profitable two-way trade between Britain and the rapidly growing United States, which did come to pass. The blockade was lifted and American merchants were free to trade with any nation anywhere in the world.
The British largely abandoned their Indigenous allies, who were not a party to this treaty and did not recognize it until they were defeated militarily by the United States. However, the British did sell them munitions and maintain forts in American territory until the Jay Treaty of 1795. Losing the war and the Thirteen Colonies was a shock to Britain. The war revealed the limitations of Britain's fiscal-military state when they discovered that they suddenly faced powerful enemies with no allies, and they were dependent on extended and vulnerable transatlantic lines of communication. The defeat heightened dissension and escalated political antagonism to the King's ministers. The King went so far as to draft letters of abdication, although they were never delivered. Inside Parliament, the primary concern changed from fears of an over-mighty monarch to the issues of representation, parliamentary reform, and government retrenchment. Reformers sought to destroy what they saw as widespread institutional corruption, and the result was a crisis from 1776 to 1783. The crisis ended after 1784 confidence in the British constitution was restored during the administration of Prime Minister William Pitt.
Finance. Britain's war against the Americans, the French, and the Spanish cost about £100 million. The Treasury borrowed 40 percent of the money that it needed. Britain had a sophisticated financial system based on the wealth of thousands of landowners who supported the government, together with banks and financiers in London. In London the British had relatively little difficulty financing their war, keeping their suppliers and soldiers paid, and hiring tens of thousands of German soldiers. In sharp contrast, Congress and the American states had no end of difficulty financing the war. In 1775, there was at most 12 million dollars in gold in the colonies, not nearly enough to cover current transactions, let alone finance a major war. The British made the situation much worse by imposing a tight blockade on every American port, which cut off almost all trade. One partial solution was to rely on volunteer support from militiamen and donations from patriotic citizens. Another was to delay actual payments, pay soldiers and suppliers in depreciated currency, and promise that it would be made good after the war. Indeed, the soldiers and officers were given land grants in 1783 to cover the wages that they had earned but had not been paid during the war. The national government did not have a strong leader in financial matters until 1781, when Robert Morris was named Superintendent of Finance of the United States. Morris used a French loan in 1782 to set up the private Bank of North America to finance the war. He reduced the civil list, saved money by using competitive bidding for contracts, tightened accounting procedures, and demanded the national government's full share of money and supplies from the individual states.
Congress used four main methods to cover the cost of the war, which cost about 66 million dollars in specie (gold and silver). Congress made issues of paper money, known colloquially as "Continental Dollars", in 1775–1780 and in 1780–1781. The first issue amounted to 242 million dollars. This paper money would supposedly be redeemed for state taxes, but the holders were eventually paid off in 1791 at the rate of one cent on the dollar. By 1780, the paper money was so devalued that the phrase "not worth a Continental" became synonymous with worthlessness. The skyrocketing inflation was a hardship on the few people who had fixed incomes, but 90 percent of the people were farmers and were not directly affected by it. Debtors benefited by paying off their debts with depreciated paper. The greatest burden was borne by the soldiers of the Continental Army whose wages were usually paid late and declined in value every month, weakening their morale and adding to the hardships of their families.
Concluding the revolution. The war ended in 1783 and was followed by a period of prosperity. The national government was still operating under the Articles of Confederation and settled the issue of the western territories, which the states ceded to Congress. American settlers moved rapidly into those areas, with Vermont, Kentucky, and Tennessee becoming states in the 1790s. However, the national government had no money either to pay the war debts owed to European nations and the private banks, or to pay Americans who had been given millions of dollars of promissory notes for supplies during the war. Nationalists led by Washington, Alexander Hamilton, and other veterans feared that the new nation was too fragile to withstand an international war, or even the repetition of internal revolts such as the Shays's Rebellion of 1786 in Massachusetts. They convinced Congress to call the Philadelphia Convention in 1787. The Convention adopted a new Constitution which provided for a republic with a much stronger national government in a federal framework, including an effective executive in a check-and-balance system with the judiciary and legislature. The Constitution was ratified in 1788, after a fierce debate in the states over the proposed new government. The new administration under President George Washington took office in New York in March 1789. James Madison spearheaded Congressional legislation proposing amendments to the Constitution as assurances to those cautious about federal power, guaranteeing many of the inalienable rights that formed a foundation for the revolution. Rhode Island was the final state to ratify the Constitution in 1790, the first ten amendments were ratified in 1791 and became known as the United States Bill of Rights.
National debt. The national debt fell into three categories after the American Revolution. The first was the $12 million owed to foreigners, mostly money borrowed from France. There was general agreement to pay the foreign debts at full value. The national government owed $40 million and state governments owed $25 million to Americans who had sold food, horses, and supplies to the Patriot forces. There were also other debts which consisted of promissory notes issued during the war to soldiers, merchants, and farmers who accepted these payments on the premise that the new Constitution would create a government that would pay these debts eventually. The war expenses of the individual states added up to $114 million, compared to $37 million by the central government. In 1790, Congress combined the remaining state debts with the foreign and domestic debts into one national debt totaling $80 million at the recommendation of first Secretary of the Treasury Alexander Hamilton. Everyone received face value for wartime certificates, so that the national honor would be sustained and the national credit established.
Ideology and factions. The population of the Thirteen States was not homogeneous in political views and attitudes. Loyalties and allegiances varied widely within regions and communities and even within families, and sometimes shifted during the Revolution. Ideology behind the revolution. The American Enlightenment was a critical precursor of the American Revolution. Chief among the ideas of the American Enlightenment were the concepts of natural law, natural rights, consent of the governed, individualism, property rights, self-ownership, self-determination, liberalism, republicanism, and defense against corruption. A growing number of American colonists embraced these views and fostered an intellectual environment which led to a new sense of political and social identity. Liberalism. John Locke is often referred to as "the philosopher of the American Revolution" due to his work in the Social Contract and Natural Rights theories that underpinned the Revolution's political ideology. Locke's "Two Treatises of Government" published in 1689 was especially influential. He argued that all humans were created equally free, and governments therefore needed the "consent of the governed". In late eighteenth-century America, belief was still widespread in "equality by creation" and "rights by creation". Locke's ideas on liberty influenced the political thinking of English writers such as John Trenchard, Thomas Gordon, and Benjamin Hoadly, whose political ideas in turn also had a strong influence on the American Patriots. His work also inspired symbols used in the American Revolution such as the "Appeal to Heaven" found on the Pine Tree Flag, which alludes to Locke's concept of the right of revolution.
The theory of the social contract influenced the belief among many of the Founders that the right of the people to overthrow their leaders, should those leaders betray the historic rights of Englishmen, was one of the "natural rights" of man. The Americans heavily relied on Montesquieu's analysis of the wisdom of the "balanced" British Constitution (mixed government) in writing the state and national constitutions. Republicanism. The American interpretation of republicanism was inspired by the Whig party in Great Britain which openly criticized the corruption within the British government. Americans were increasingly embracing republican values, seeing Britain as corrupt and hostile to American interests. The colonists associated political corruption with ostentatious luxury and inherited aristocracy. The Founding Fathers were strong advocates of republican values, particularly Samuel Adams, Patrick Henry, John Adams, Benjamin Franklin, Thomas Jefferson, Thomas Paine, George Washington, James Madison, and Alexander Hamilton, which required men to put civic duty ahead of their personal desires. Men were honor bound by civic obligation to be prepared and willing to fight for the rights and liberties of their countrymen. John Adams wrote to Mercy Otis Warren in 1776, agreeing with some classical Greek and Roman thinkers: "Public Virtue cannot exist without private, and public Virtue is the only Foundation of Republics." He continued:
Protestant dissenters and the Great Awakening. Protestant churches that had separated from the Church of England, called "dissenters", were the "school of democracy", in the words of historian Patricia Bonomi. Before the Revolution, the Southern Colonies and three of the New England Colonies had official established churches: Congregational in Massachusetts Bay, Connecticut, and New Hampshire, and the Church of England in Maryland, Virginia, North-Carolina, South Carolina, and Georgia. The New York, New Jersey, Pennsylvania, Delaware, and the Colony of Rhode Island and Providence Plantations had no officially established churches. Church membership statistics from the period are unreliable and scarce, but what little data exists indicates that the Church of England was not in the majority, not even in the colonies where it was the established church, and they probably did not comprise even 30 percent of the population in most localities (with the possible exception of Virginia). John Witherspoon, who was considered a "new light" Presbyterian, wrote widely circulated sermons linking the American Revolution to the teachings of the Bible. Throughout the colonies, dissenting Protestant ministers from the Congregational, Baptist, and Presbyterian churches preached Revolutionary themes in their sermons while most Church of England clergymen preached loyalty to the king, the titular head of the English state church. Religious motivation for fighting tyranny transcended socioeconomic lines. The Declaration of Independence also referred to the "Laws of Nature and of Nature's God" as justification for the Americans' separation from the British monarchy: the signers of the Declaration professed their "firm reliance on the Protection of divine Providence", and they appealed to "the Supreme Judge for the rectitude of our intentions".
Historian Bernard Bailyn argues that the evangelicalism of the era challenged traditional notions of natural hierarchy by preaching that the Bible teaches that all men are equal, so that the true value of a man lies in his moral behavior, not in his class. Kidd argues that religious disestablishment, belief in God as the source of human rights, and shared convictions about sin, virtue, and divine providence worked together to unite rationalists and evangelicals and thus encouraged a large proportion of Americans to fight for independence from the Empire. Bailyn, on the other hand, denies that religion played such a critical role. Alan Heimert argues that New Light anti-authoritarianism was essential to furthering democracy in colonial American society, and set the stage for a confrontation with British monarchical and aristocratic rule. Class and psychology of the factions. John Adams concluded in 1818: In the mid-20th century, historian Leonard Woods Labaree identified eight characteristics of the Loyalists that made them essentially conservative, opposite to the characteristics of the Patriots. Loyalists tended to feel that resistance to the Crown was morally wrong, while the Patriots thought that morality was on their side. Loyalists were alienated when the Patriots resorted to violence, such as burning houses and tarring and feathering. Loyalists wanted to take a centrist position and resisted the Patriots' demand to declare their opposition to the Crown. Many Loyalists had maintained strong and long-standing relations with Britain, especially merchants in port cities such as New York and Boston. Many Loyalists felt that independence was bound to come eventually, but they were fearful that revolution might lead to anarchy, tyranny, or mob rule. In contrast, the prevailing attitude among Patriots was a desire to seize the initiative. Labaree also wrote that Loyalists were pessimists who lacked the confidence in the future displayed by the Patriots.
Historians in the early 20th century such as J. Franklin Jameson examined the class composition of the Patriot cause, looking for evidence of a class war inside the revolution. More recent historians have largely abandoned that interpretation, emphasizing instead the high level of ideological unity. Both Loyalists and Patriots were a "mixed lot", but ideological demands always came first. The Patriots viewed independence as a means to gain freedom from British oppression and to reassert their basic rights. Most yeomen farmers, craftsmen, and small merchants joined the Patriot cause to demand more political equality. They were especially successful in Pennsylvania but less so in New England, where John Adams attacked Thomas Paine's "Common Sense" for the "absurd democratical notions" that it proposed. King George III. The revolution became a personal issue for the king, fueled by his growing belief that British leniency would be taken as weakness by the Americans. He also sincerely believed that he was defending Britain's constitution against usurpers, rather than opposing patriots fighting for their natural rights.
King George III is often accused of obstinately trying to keep Great Britain at war with the revolutionaries in America, despite the opinions of his own ministers. In the words of the British historian George Otto Trevelyan, the King was determined "never to acknowledge the independence of the Americans, and to punish their contumacy by the indefinite prolongation of a war which promised to be eternal." The king wanted to "keep the rebels harassed, anxious, and poor, until the day when, by a natural and inevitable process, discontent and disappointment were converted into penitence and remorse". Later historians defend George by saying in the context of the times no king would willingly surrender such a large territory, and his conduct was far less ruthless than contemporary monarchs in Europe. After the surrender of a British army at Saratoga, both Parliament and the British people were largely in favor of the war; recruitment ran at high levels and although political opponents were vocal, they remained a small minority.
With the setbacks in America, Lord North asked to transfer power to Lord Chatham, whom he thought more capable, but George refused to do so; he suggested instead that Chatham serve as a subordinate minister in North's administration, but Chatham refused. He died later in the same year. Lord North was allied to the "King's Friends" in Parliament and believed George III had the right to exercise powers. In early 1778, Britain's chief rival France signed a treaty of alliance with the United States, and the confrontation soon escalated from a "rebellion" to something that has been characterized as "world war". The French fleet was able to outrun the British naval blockade of the Mediterranean and sailed to North America. The conflict now affected North America, Europe and India. The United States and France were joined by Spain in 1779 and the Dutch Republic, while Britain had no major allies of its own, except for the Loyalist minority in America and German auxiliaries (i.e. "Hessians"). Lord Gower and Lord Weymouth both resigned from the government. Lord North again requested that he also be allowed to resign, but he stayed in office at George III's insistence. Opposition to the costly war was increasing, and in June 1780 contributed to disturbances in London known as the Gordon riots.
As late as the Siege of Charleston in 1780, Loyalists could still believe in their eventual victory, as British troops inflicted defeats on the Continental forces at the Battle of Camden and the Battle of Guilford Court House. In late 1781, the news of Cornwallis's surrender at the siege of Yorktown reached London; Lord North's parliamentary support ebbed away and he resigned the following year. The king drafted an abdication notice, which was never delivered, finally accepted the defeat in North America, and authorized peace negotiations. The Treaties of Paris, by which Britain recognized the independence of the United States and returned Florida to Spain, were signed in 1782 and 1783 respectively. In early 1783, George III privately conceded "America is lost!" He reflected that the Northern colonies had developed into Britain's "successful rivals" in commercial trade and fishing. When John Adams was appointed American Minister to London in 1785, George had become resigned to the new relationship between his country and the former colonies. He told Adams, "I was the last to consent to the separation; but the separation having been made and having become inevitable, I have always said, as I say now, that I would be the first to meet the friendship of the United States as an independent power."
Patriots. Those who fought for independence were called "Revolutionaries", "Continentals", "Rebels", "Patriots", "Whigs", "Congress-men", or "Americans" during and after the war. They included a full range of social and economic classes but were unanimous regarding the need to defend the rights of Americans and uphold the principles of republicanism in rejecting monarchy and aristocracy, while emphasizing civic virtue by citizens. The signers of the Declaration of Independence were mostly—with definite exceptions—well-educated, of British stock, and of the Protestant faith. Newspapers were strongholds of patriotism (although there were a few Loyalist papers) and printed many pamphlets, announcements, patriotic letters, and pronouncements. According to historian Robert Calhoon, 40 to 45 percent of the white population in the Thirteen Colonies supported the Patriots' cause, 15 to 20 percent supported the Loyalists, and the remainder were neutral or kept a low profile. Mark Lender concludes that ordinary people became insurgents against the British because they held a sense of rights which the British were violating, rights that stressed local autonomy, fair dealing, and government by consent. They were highly sensitive to the issue of tyranny, which they saw manifested in the British response to the Boston Tea Party. The arrival in Boston of the British Army heightened their sense of violated rights, leading to rage and demands for revenge. They had faith that God was on their side.
Thomas Paine published his pamphlet "Common Sense" in January 1776, after the Revolution had started. It was widely distributed and often read aloud in taverns, contributing significantly to concurrently spreading the ideas of republicanism and liberalism, bolstering enthusiasm for separation from Great Britain and encouraging recruitment for the Continental Army. Paine presented the Revolution as the solution for Americans alarmed by the threat of tyranny. Loyalists. The consensus of scholars is that about 15 to 20 percent of the white population remained loyal to the British Crown. Those who actively supported the king were known at the time as "Loyalists", "Tories", or "King's men". The Loyalists never controlled territory unless the British Army occupied it. They were typically older, less willing to break with old loyalties, and often connected to the Church of England; they included many established merchants with strong business connections throughout the Empire, as well as royal officials such as Thomas Hutchinson of Boston.
There were 500 to 1,000 Black Loyalists, enslaved African Americans who escaped to British lines and supported Britain's cause via several means. Many of them died from disease, but the survivors were evacuated by the British to their remaining colonies in North America. The revolution could divide families, such as William Franklin, son of Benjamin Franklin and royal governor of the Province of New Jersey who remained loyal to the Crown throughout the war. He and his father never spoke again. Recent immigrants who had not been fully Americanized were also inclined to support the King. After the war, the great majority of the half-million Loyalists remained in America and resumed normal lives. Some became prominent American leaders, such as Samuel Seabury. Approximately 46,000 Loyalists relocated to Canada; others moved to Britain (7,000), Florida, or the West Indies (9,000). The exiles represented approximately two percent of the total population of the colonies. Nearly all Black Loyalists left for Nova Scotia, Florida, or England, where they could remain free. Loyalists who left the South in 1783 took thousands of their slaves with them as they fled to the British West Indies.
Neutrals. A minority of uncertain size tried to stay neutral in the war. Most kept a low profile, but the Quakers were the most important group to speak out for neutrality, especially in Pennsylvania. The Quakers continued to do business with the British even after the war began, and they were accused of supporting British rule, "contrivers and authors of seditious publications" critical of the revolutionary cause. Most Quakers remained neutral, although a sizeable number participated to some degree. Role of women. Women contributed to the American Revolution in many ways and were involved on both sides. Formal politics did not include women, but ordinary domestic behaviors became charged with political significance as Patriot women confronted a war which permeated all aspects of political, civil, and domestic life. They participated by boycotting British goods, spying on the British, following armies as they marched, washing, cooking, and mending for soldiers, delivering secret messages, and even fighting disguised as men in a few cases, such as Deborah Samson. Mercy Otis Warren held meetings in her house and cleverly attacked Loyalists with her creative plays and histories. Many women also acted as nurses and helpers, tending to the soldiers' wounds and buying and selling goods for them. Some of these camp followers even participated in combat, such as Madam John Turchin who led her husband's regiment into battle. Above all, women continued the agricultural work at home to feed their families and the armies. They maintained their families during their husbands' absences and sometimes after their deaths.
American women were integral to the success of the boycott of British goods, as the boycotted items were largely household articles such as tea and cloth. Women had to return to knitting goods and to spinning and weaving their own cloth—skills that had fallen into disuse. In 1769, the women of Boston produced 40,000 skeins of yarn, and 180 women in Middletown, Massachusetts wove of cloth. Many women gathered food, money, clothes, and other supplies during the war to help the soldiers. A woman's loyalty to her husband could become an open political act, especially for women in America committed to men who remained loyal to the King. Legal divorce, usually rare, was granted to Patriot women whose husbands supported the King. Other participants. France and Spain. In early 1776, France set up a major program of aid to the Americans, and the Spanish secretly added funds. Each country spent one million "livres tournaises" to buy munitions. A dummy corporation run by Pierre Beaumarchais concealed their activities. American Patriots obtained some munitions from the Dutch Republic as well, through the French and Spanish ports in the West Indies. Heavy expenditures and a weak taxation system pushed France toward bankruptcy.
In 1777, Charles François Adrien le Paulmier, Chevalier d'Annemours, acting as a secret agent for France, made sure General George Washington was privy to his mission. He followed Congress around for the next two years, reporting what he observed back to France. The Treaty of Alliance between the French and the Americans followed in 1778, which led to more French money, matériel and troops being sent to the United States. Spain did not officially recognize the United States, but it was a French ally and it separately declared war on Britain on June 21, 1779. Bernardo de Gálvez, general of the Spanish forces in New Spain, also served as governor of Louisiana. He led an expedition of colonial troops to capture Florida from the British and to keep open a vital conduit for supplies going to the Americans. Germans. Ethnic Germans served on both sides of the American Revolutionary War. As George III was also the Elector of Hanover, many supported the Loyalist cause and served as allies of the Kingdom of Great Britain; most notably rented auxiliary troops from German states such as the Landgraviate of Hessen-Kassel.
American Patriots tended to represent such troops as mercenaries in propaganda against the British Crown. Even American historians followed suit, in spite of Colonial-era jurists drawing a distinction between auxiliaries and mercenaries, with auxiliaries serving their prince when sent to the aid of another prince, and mercenaries serving a foreign prince as individuals. By this distinction the troops which served in the American Revolution were auxiliaries. Other German individuals came to assist the American revolutionaries, most notably Friedrich Wilhelm von Steuben, who served as a general in the Continental Army and is credited with professionalizing that force, but most Germans who served were already colonists. Von Steuben's native Prussia joined the League of Armed Neutrality, and King Frederick II of Prussia was well appreciated in the United States for his support early in the war. He expressed interest in opening trade with the United States and bypassing English ports, and allowed an American agent to buy arms in Prussia. Frederick predicted American success, and promised to recognize the United States and American diplomats once France did the same. Prussia also interfered in the recruiting efforts of Russia and neighboring German states when they raised armies to send to the Americas, and Frederick II forbade enlistment for the American war within Prussia. All Prussian roads were denied to troops from Anhalt-Zerbst, which delayed reinforcements that Howe had hoped to receive during the winter of 1777–1778.
However, when the War of the Bavarian Succession (1778–1779) erupted, Frederick II became much more cautious with Prussian/British relations. U.S. ships were denied access to Prussian ports, and Frederick refused to officially recognize the United States until they had signed the Treaty of Paris. Even after the war, Frederick II predicted that the United States was too large to operate as a republic, and that it would soon rejoin the British Empire with representatives in Parliament. Native Americans. Most Indigenous people rejected pleas that they remain neutral and instead supported the British Crown. The great majority of the 200,000 Indigenous people east of the Mississippi distrusted the Americans and supported the British cause, hoping to forestall continued expansion of settlement into their territories. Those tribes closely involved in trade tended to side with the Patriots, although political factors were important as well. Some tried to remain neutral, seeing little value in joining what they perceived to be a "white man's war", and fearing reprisals from whichever side they opposed.
The great majority of Indigenous people did not participate directly in the war, with the notable exceptions of warriors and bands associated with four of the Iroquois tribes in New York and Pennsylvania which allied with the British, and the Oneida and Tuscarora tribes among the Iroquois of central and western New York who supported the American cause. The British did have other allies, particularly in the regions of southwest Quebec on the Patriot's frontier. The British provided arms to Indigenous people who were led by Loyalists in war parties to raid frontier settlements from the Carolinas to New York. These war parties managed to kill many settlers on the frontier, especially in Pennsylvania and New York's Mohawk Valley. In 1776, Cherokee war parties attacked American Colonists all along the southern Quebec frontier of the uplands throughout the Washington District, North Carolina (now Tennessee) and the Kentucky wilderness area. The Chickamauga Cherokee under Dragging Canoe allied themselves closely with the British, and fought on for an additional decade after the Treaty of Paris was signed. They launched raids with roughly 200 warriors, as seen in the Cherokee–American wars; they could not mobilize enough forces to invade settler areas without the help of allies, most often the Creek.
Joseph Brant ("also" Thayendanegea) of the powerful Mohawk tribe in New York was the most prominent Indigenous leader against the Patriot forces. In 1778 and 1780, he led 300 Iroquois warriors and 100 white Loyalists in multiple attacks on small frontier settlements in New York and Pennsylvania, killing many settlers and destroying villages, crops, and stores. In 1779, the Continental Army forced the hostile Indigenous people out of upstate New York when Washington sent an army under John Sullivan which destroyed 40 evacuated Iroquois villages in central and western New York. The Battle of Newtown proved decisive, as the Patriots had an advantage of three-to-one, and it ended significant resistance; there was little combat otherwise. Facing starvation and homeless for the winter, the Iroquois fled to Canada. At the peace conference following the war, the British ceded lands which they did not really control, without consultation with their Indigenous allies. They transferred control to the United States of all the land south of the Great Lakes east of the Mississippi and north of Florida. Calloway concludes:
Black Americans. Free Blacks in the New England Colonies and Middle Colonies in the North as well as Southern Colonies fought on both sides of the War, but the majority fought for the Patriots. Gary Nash reports that there were about 9,000 Black veteran Patriots, counting the Continental Army and Navy, state militia units, privateers, wagoneers in the Army, servants to officers, and spies. Ray Raphael notes that thousands did join the Loyalist cause, but "a far larger number, free as well as slave, tried to further their interests by siding with the patriots." Crispus Attucks was one of the five people killed in the Boston Massacre in 1770 and is considered the first American casualty for the cause of independence. The effects of the war were more dramatic in the South. Tens of thousands of slaves escaped to British lines throughout the South, causing dramatic losses to slaveholders and disrupting cultivation and harvesting of crops. For instance, South Carolina was estimated to have lost about 25,000 slaves to flight, migration, or death which amounted to a third of its slave population.
During the war, the British commanders attempted to weaken the Patriots by issuing proclamations of freedom to their slaves. In the November 1775 document known as Dunmore's Proclamation Virginia royal governor, Lord Dunmore recruited Black men into the British forces with the promise of freedom, protection for their families, and land grants. Some men responded and briefly formed the British Ethiopian Regiment. Historian David Brion Davis explains the difficulties with a policy of wholesale arming of the slaves: Davis underscores the British dilemma: "Britain, when confronted by the rebellious American colonists, hoped to exploit their fear of slave revolts while also reassuring the large number of slave-holding Loyalists and wealthy Caribbean planters and merchants that their slave property would be secure". The Americans, however, accused the British of encouraging slave revolts, with the issue becoming one of the 27 colonial grievances. The existence of slavery in the American colonies had attracted criticism from both sides of the Atlantic as many could not reconcile the existence of the institution with the egalitarian ideals espoused by leaders of the Revolution. British writer Samuel Johnson wrote "how is it we hear the loudest yelps for liberty among the drivers of the Negroes?" in a text opposing the grievances of the colonists. Referring to this contradiction, English abolitionist Thomas Day wrote in a 1776 letter that Thomas Jefferson unsuccessfully attempted to include a section in the Declaration of Independence which asserted that King George III had "forced" the slave trade onto the colonies. Despite the turmoil of the period, African-Americans contributed to the foundation of an American national identity during the Revolution. Phyllis Wheatley, an African-American poet, popularized the image of Columbia to represent America.
The 1779 Philipsburg Proclamation expanded the promise of freedom for Black men who enlisted in the British military to all the colonies in rebellion. British forces gave transportation to 10,000 slaves when they evacuated Savannah and Charleston, carrying through on their promise. They evacuated and resettled more than 3,000 Black Loyalists from New York to Nova Scotia, Upper Canada, and Lower Canada. Others sailed with the British to England or were resettled as freedmen in the West Indies of the Caribbean. But slaves carried to the Caribbean under control of Loyalist masters generally remained slaves until British abolition of slavery in its colonies in 1833–1838. More than 1,200 of the Black Loyalists of Nova Scotia later resettled in the British colony of Sierra Leone, where they became leaders of the Krio ethnic group of Freetown and the later national government. Many of their descendants still live in Sierra Leone, as well as other African countries. Effects of the revolution. After the Revolution, genuinely democratic politics became possible in the former American colonies. The rights of the people were incorporated into state constitutions. Concepts of liberty, individual rights, equality among men and hostility toward corruption became incorporated as core values of liberal republicanism. The new United States government was empowered to undertake its own project of territorial expansion and settler colonialism. The greatest challenge to the old order in Europe was the challenge to inherited political power and the democratic idea that government rests on the consent of the governed. The example of the first successful revolution against a European empire, and the first successful establishment of a republican form of democratically elected government, provided a model for many other colonial peoples who realized that they too could break away and become self-governing nations with directly elected representative government.
Interpretations. Interpretations vary concerning the effect of the Revolution. Historians such as Bernard Bailyn, Gordon Wood, and Edmund Morgan view it as a unique and radical event which produced deep changes and had a profound effect on world affairs, such as an increasing belief in the principles of the Enlightenment. These were demonstrated by a leadership and government that espoused protection of natural rights, and a system of laws chosen by the people. John Murrin, by contrast, argues that the definition of "the people" at that time was mostly restricted to free men who passed a property qualification. Gordon Wood states: Edmund Morgan has argued that, in terms of long-term impact on American society and values: Inspiring other independence movements and revolutions. The first shot of the American Revolution at the Battle of Lexington and Concord is referred to as the "shot heard 'round the world". The Revolutionary War victory not only established the United States as the first modern constitutional republic, but marked the transition from an age of monarchy to a new age of freedom by inspiring similar movements worldwide. The American Revolution was the first of the "Atlantic Revolutions": followed most notably by the French Revolution, the Haitian Revolution, and the Latin American wars of independence. Aftershocks contributed to rebellions in Ireland, the Polish–Lithuanian Commonwealth, and the Netherlands.
The U.S. Constitution, drafted shortly after independence, remains the world's oldest written constitution, and has been emulated by other countries, in some cases verbatim. Some historians and scholars argue that the subsequent wave of independence and revolutionary movements has contributed to the continued expansion of democratic government; 144 countries, representing two-third of the world's population, are full or partially democracies of same form. The Dutch Republic, also at war with Britain, was the next country after France to sign a treaty with the United States, on October 8, 1782. On April 3, 1783, Ambassador Extraordinary Gustaf Philip Creutz, representing King Gustav III of Sweden, and Benjamin Franklin, signed a Treaty of Amity and Commerce with the U.S. The Revolution had a strong, immediate influence in Great Britain, Ireland, the Netherlands, and France. Many British and Irish Whigs in Parliament spoke glowingly in favor of the American cause. In Ireland, the Protestant minority who controlled Ireland demanded self-rule. Under the leadership of Henry Grattan, the Irish Patriot Party forced the reversal of mercantilist prohibitions against trade with other British colonies. The King and his cabinet in London could not risk another rebellion, and so made a series of concessions to the Patriot faction in Dublin. Armed volunteer units of the "Protestant Ascendancy" were set up ostensibly to protect against an invasion from France. As had been in colonial America, so too in Ireland now the King no longer had a monopoly of lethal force.
For many Europeans, such as the Marquis de Lafayette, who later were active during the era of the French Revolution, the American case along with the Dutch Revolt (end of the 16th century) and the 17th century English Civil War, was among the examples of overthrowing an old regime. The American Declaration of Independence influenced the French Declaration of the Rights of Man and of the Citizen of 1789. The spirit of the Declaration of Independence led to laws ending slavery in all the Northern states and the Northwest Territory, with New Jersey the last in 1804. States such as New Jersey and New York adopted gradual emancipation, which kept some people as slaves for more than two decades longer. Status of African Americans. During the revolution, the contradiction between the Patriots' professed ideals of liberty and the institution of slavery generated increased scrutiny of the latter. As early as 1764, the Boston Patriot leader James Otis, Jr. declared that all men, "white or black", were "by the law of nature" born free. Anti-slavery calls became more common in the early 1770s. In 1773, Benjamin Rush, the future signer of the Declaration of Independence, called on "advocates for American liberty" to oppose slavery. Slavery became an issue that had to be addressed. As historian Christopher L. Brown put it, slavery "had never been on the agenda in a serious way before," but the Revolution "forced it to be a public question from there forward."
In the late 1760s and early 1770s, several colonies, including Massachusetts and Virginia, attempted to restrict the slave trade, but were prevented from doing so by royally appointed governors. In 1774, as part of a broader non-importation movement aimed at Britain, the Continental Congress called on all the colonies to ban the importation of slaves, and the colonies passed acts doing so. In the first two decades after the American Revolution, state legislatures and individuals took actions to free slaves, in part based on revolutionary ideals. Northern states passed new constitutions that contained language about equal rights or specifically abolished slavery; some states, such as New York and New Jersey, where slavery was more widespread, passed laws by the end of the 18th century to abolish slavery by a gradual method. By 1804, all the northern states had passed laws outlawing slavery, either immediately or over time. No southern state abolished slavery. However, individual owners could free their slaves by personal decision. Numerous slaveholders who freed their slaves cited revolutionary ideals in their documents; others freed slaves as a reward for service. Records also suggest that some slaveholders were freeing their own mixed-race children, born into slavery to slave mothers. The number of free Blacks as a proportion of the Black population in the upper South increased from less than 1 percent to nearly 10 percent between 1790 and 1810 as a result of these actions. Nevertheless, slavery continued in the South, where it became a "peculiar institution", setting the stage for future sectional conflict between North and South over the issue.
Thousands of free Blacks in the northern states fought in the state militias and Continental Army. In the south, both sides offered freedom to slaves who would perform military service. Roughly 20,000 slaves fought in the American Revolution. Status of American women. The status of women during the Revolutionary War can be illustrated by the interchange of gender, sexuality, citizenship, and class. While women were entering a period in which they found themselves gaining more identity within society, it was clear that they were still very much considered under men as their role in society remained being a good wife and mother. Their clothes, the way they responded to their husband, and listened to their husband, was incredibly important in the social sphere. Having a woman who was dressed well for her role as a good wife and mother as well as fitting the social role, was a symbol of not only status, but a family devoted to the republic. As they continued to nurture social and political partnerships, their role in enabling the success of the revolution emphasized their changing role in society – leading to the post-revolutionary reconstruction of gender ideology.
The democratic ideals of the Revolution inspired changes in the roles of women. Patriot women married to Loyalists who left the state could get a divorce and obtain control of the ex-husband's property. Abigail Adams expressed to her husband, the president, the desire of women to have a place in the new republic: The Revolution sparked a discussion on the rights of woman and an environment favorable to women's participation in politics. Briefly the possibilities for women's rights were highly favorable, but a backlash led to a greater rigidity that excluded women from politics. Soon after the Revolutionary War, Mary Wallostonecraft would publish: "Vindication of the Rights of Woman" (1792) – challenging the idea that rights should only be granted to men. Her radical ideas would give ground to the conversation in allowing women to be bearers of rights alongside men – that while the rights of man were taking on a new meaning post-revolutionary America, it was time for the rights of women too. However, this new sense of independence and dignity did not come with ease, as a gender hierarchy would continue to bound what it meant for women to have rights during the Post-Revolutionary era.
Women's rights were founded on the Scottish theory that treated rights simply as benefits . The emphasis was on duty and obligation, instead of liberty and choice – confining women to the traditional role of wife and mother. On the other hand, men's rights were heavily inspired by Locke, as it emphasized equality, individual autonomy, and the expansion of personal freedoms. So while women were becoming bearers of rights, the foundation and philosophy of those given rights differed vastly. The early national period of America would continue to struggle with the concept of rights and equality, as women faced the notion that women should be under the dominance of men – carried by Christian beliefs. Women were blamed for the “Fall of Man”, in reference to Eve and Adam in the Bible. So while women were beginning to bear rights, the type of language that was being used when talking about the rights of women was done with care and hesitance. For more than thirty years, however, the 1776 New Jersey State Constitution gave the vote to "all inhabitants" who had a certain level of wealth, including unmarried women and blacks (not married women because they could not own property separately from their husbands), until in 1807, when that state legislature passed a bill interpreting the constitution to mean universal "white male" suffrage, excluding paupers.
Loyalist expatriation. Tens of thousands of Loyalists left the United States following the war; Philip Ranlet estimates 20,000, while Maya Jasanoff estimates as many as 70,000. Some migrated to Britain, but the great majority received land and subsidies for resettlement in British colonies in North America, especially Quebec (concentrating in the Eastern Townships), Prince Edward Island, and Nova Scotia. Britain created the colonies of Upper Canada (Ontario) and New Brunswick expressly for their benefit, and the Crown awarded land to Loyalists as compensation for losses in the United States. Nevertheless, approximately eighty-five percent of the Loyalists stayed in the United States as American citizens, and some of the exiles later returned to the U.S. Patrick Henry spoke of the issue of allowing Loyalists to return as such: "Shall we, who have laid the proud British lion at our feet, be frightened of its whelps?" His actions helped secure return of the Loyalists to American soil. Commemorations. The American Revolution has a central place in the American memory as the story of the nation's founding. It is covered in the schools, memorialized by two national holidays, Washington's Birthday in February and Independence Day in July, and commemorated in innumerable monuments. George Washington's estate at Mount Vernon was one of the first national pilgrimages for tourists and attracted 10,000 visitors a year by the 1850s.
The Revolution became a matter of contention in the 1850s in the debates leading to the American Civil War (1861–1865), as spokesmen of both the Northern United States and the Southern United States claimed that their region was the true custodian of the legacy of 1776. The United States Bicentennial in 1976 came a year after the American withdrawal from the Vietnam War, and speakers stressed the themes of renewal and rebirth based on a restoration of traditional values. Today, more than 100 are protected and maintained by the government. The National Park Service alone manages and maintains more than 50 battlefield parks and many other sites such as Independence Hall that are related to the Revolution. The private American Battlefield Trust uses government grants and other funds to preserve almost 700 acres of battlefield land in six states, and the ambitious private recreation/restoration/preservation/interpretation of over 300 acres of pre-1790 Colonial Williamsburg was created in the first half of the 20th century for public visitation.
Alan Ayckbourn Sir Alan Ayckbourn (born 12 April 1939) is a prolific British playwright and director. As of 2025, he has written and produced 90 full-length plays in Scarborough and London and was, between 1972 and 2009, the artistic director of the Stephen Joseph Theatre in Scarborough, where all but four of his plays have received their first performance. More than 40 have subsequently been produced in the West End, at the Royal National Theatre or by the Royal Shakespeare Company since his first hit "Relatively Speaking" opened at the Duke of York's Theatre in 1967. Major successes include "Absurd Person Singular" (1975), "The Norman Conquests" trilogy (1973), "Bedroom Farce" (1975), "Just Between Ourselves" (1976), "A Chorus of Disapproval" (1984), "Woman in Mind" (1985), "A Small Family Business" (1987), "Man of the Moment" (1988), "House" & "Garden" (1999) and "Private Fears in Public Places" (2004). His plays have won numerous awards, including seven London "Evening Standard" Awards. They have been translated into over 35 languages and are performed on stage and television throughout the world. Ten of his plays have been staged on Broadway, attracting two Tony nominations, and one Tony award.
Life. Childhood. Ayckbourn was born in Hampstead, London. His mother, Irene Worley ("Lolly") (1906–1998), was a writer of short stories who published under the name "Mary James". His father, Horace Ayckbourn (1904–1965), was an orchestral violinist and was the lead violinist at the London Symphony Orchestra. His parents, who separated shortly after World War II, never married, and Ayckbourn's mother divorced her first husband to marry again in 1948. Ayckbourn wrote his first play at Wisborough Lodge (a preparatory school in the village of Wisborough Green) when he was about 10. While he was at prep school as a boarder, his mother wrote to tell him she was marrying Cecil Pye, a bank manager. His new family consisted of his mother, his stepfather and Christopher, his stepfather's son by an earlier marriage. This relationship too, reportedly ran into difficulties early on. Ayckbourn attended Haileybury and Imperial Service College, in the village of Hertford Heath and, while there, he toured Europe and America with the school's Shakespeare company.
Adult life. After leaving school at 17, Ayckbourn took several temporary jobs in various places before starting a temporary position at the Scarborough Library Theatre, where he was introduced to the artistic director, Stephen Joseph. It is said that Joseph became both a mentor and father figure for Ayckbourn until his untimely death in 1967, and Ayckbourn has consistently spoken highly of him. Ayckbourn's career was briefly interrupted when he was called up for National Service. He was swiftly discharged, officially on medical grounds, but it is suggested that a doctor who noticed his reluctance to join the Armed Forces deliberately failed the medical as a favour. Although Ayckbourn continued to move wherever his career took him, he settled in Scarborough, eventually buying Longwestgate House, which had previously been owned by his mentor, Joseph. In 1957, Ayckbourn married Christine Roland, another member of the Library Theatre company. Ayckbourn's first two plays were, in fact, written jointly with her under the pseudonym of "Roland Allen". They had two sons, Steven and Philip. However, the marriage had difficulties, which eventually led to their separation in 1971. Ayckbourn said that his relationship with Roland became easy once they agreed their marriage was over. About this time, he shared a home with Heather Stoney, an actress he had first met ten years earlier. Like his mother, neither he nor Roland sought an immediate divorce and it was not until thirty years later, in 1997, that they were formally divorced and Ayckbourn married Stoney. One side effect of the timing is that, when Ayckbourn was awarded a knighthood a few months before the divorce, both his first and second wives were entitled to take the title of Lady Ayckbourn.
In February 2006, he suffered a stroke in Scarborough, and stated: "I hope to be back on my feet, or should I say my left leg, as soon as possible, but I know it is going to take some time. In the meantime I am in excellent hands and so is the Stephen Joseph Theatre." He left hospital after eight weeks and returned to directing after six months. The following year, Ayckbourn announced he would step down as artistic director of the Stephen Joseph Theatre. He continues, however, to write and direct his own work at the theatre. Influence on plays. Since the time Ayckbourn's plays became established in the West End, interviewers have raised the question of whether his work is autobiographical. There is no clear answer to this question. There has been only one biography, written by Paul Allen, which primarily covers his career in the theatre. Ayckbourn has frequently said he sees aspects of himself in all of his characters. In "Bedroom Farce" (1975), for example, he admitted to being, in some respects, all four of the men in the play. It has been suggested that, after Ayckbourn himself, the person who is used most often in his plays is his mother, particularly as Susan in "Woman in Mind" (1985).
What is less clear is the extent to which events in Ayckbourn's life have influenced his writing. It is true that the theme of marriages in difficulty was heavily present throughout his plays in the early seventies, at about the time his own marriage was coming to an end. However, by that time, he had also witnessed the failure of his parents' relationships and those of some of his friends. Which relationships, if any, he drew on for his plays, is unclear. In Paul Allen's biography, Ayckbourn is briefly compared with Dafydd and Guy in "A Chorus of Disapproval" (1984). Both characters feel themselves to be in trouble and there was speculation that Ayckbourn himself might have felt the same way. At the time, he had reportedly become seriously involved with another actress, which threatened his relationship with Stoney. It is unclear whether this had any effect on the writing; Paul Allen's view is that Ayckbourn did not use his personal experiences to write his plays. It is possible that Ayckbourn wrote plays with himself and his own situation in mind but, as Ayckbourn is portrayed as a guarded and private man, it is hard to imagine him exposing his own life in his plays to any great degree. In the biography, Paul Allen writes, with regard to a suggestion in "Cosmopolitan" that Ayckbourn's plays were becoming autobiographical: "If we take that to mean that his plays tell his own life story, he still hasn't started."
Career. Early career and acting. On leaving school, Ayckbourn's theatrical career began immediately, when his French master introduced him to Sir Donald Wolfit. Ayckbourn joined Wolfit on tour to the Edinburgh Festival Fringe as an acting assistant stage manager (a role that involved both acting and stage management) for three weeks. His first experiences on the professional stage were various roles in "The Strong are Lonely" by Fritz Hochwälder. In the following year, Ayckbourn appeared in six other plays at the Connaught Theatre, Worthing and the Thorndike theatre, Leatherhead where Hazel Vincent Wallace employed him as both an actor and an assistant stage manager. In 1957, Ayckbourn was employed by the director Stephen Joseph at the Library Theatre, Scarborough, the predecessor to the modern Stephen Joseph Theatre. Again, his role was initially as acting stage manager. This employment led to Ayckbourn's first professional script commission, in 1958. When he complained about the quality of a script he was performing, Joseph challenged him to write a better one. The result was "The Square Cat", written under the pseudonym Roland Allen and first performed in 1959. In this play, Ayckbourn himself played the character of Jerry Watiss.
In 1962, after thirty-four appearances in plays at the Library Theatre, including four of his own, Ayckbourn moved to Stoke-on-Trent to help set up the Victoria Theatre (now the New Vic), where he appeared in a further eighteen plays. His final appearance in one of his own plays was as the Crimson Gollywog in the disastrous children's play "Christmas v Mastermind". He left the Stoke company in 1964, officially to commit his time to the London production of "Mr. Whatnot", but reportedly because was having trouble working with the artistic director, Peter Cheeseman. By now, his career as a writer was coming to fruition and his acting career was sidelined. His final role on stage was as Jerry in "Two for the Seesaw" by William Gibson, at the Civic Theatre in Rotherham. He was left stranded on stage because Heather Stoney (his future wife) was unable to re-appear due to her props not being ready for use. This led to his conclusion that acting was more trouble than it was worth. The assistant stage manager on the production, Bill Kenwright, would go on to become one of the UK's most successful producers.
Writing. Ayckbourn's first play, "The Square Cat", was sufficiently popular locally to secure further commissions, although neither this nor the following three plays had much impact beyond Scarborough. After his transfer to Victoria Theatre in Stoke-on-Trent, "Christmas v Mastermind", flopped; this play is now universally regarded as Ayckbourn's greatest disaster. Ayckbourn's fortunes revived in 1963 with "Mr. Whatnot", which also premiered at the Victoria Theatre. This was the first play that Ayckbourn was sufficiently happy with to allow continued performances today, and the first play to receive a West End performance. However, the West End production flopped, in part due to misguided casting. After this, Ayckbourn experimented by collaborating with comedians, first writing a monologue for Tommy Cooper, and later with Ronnie Barker, who played Lord Slingsby-Craddock in the London production of "Mr Whatnot" in 1964, on the scripts for LWT's "Hark at Barker". Ayckbourn used the pseudonym Peter Caulfield because he was under exclusive contract to the BBC at the time.
In 1965, back at the Scarborough Library Theatre, "Meet my Father" was produced, and later retitled "Relatively Speaking". This time, the play was a massive success, both in Scarborough and in the West End, earning Ayckbourn a congratulatory telegram from Noël Coward. This was not quite the end of Ayckbourn's hit-and-miss record. His next play, "The Sparrow" ran for only three weeks at Scarborough but the following play, "How the Other Half Loves", secured his runaway success as a playwright. The height of Ayckbourn's commercial success came with plays such as "Absurd Person Singular" (1975), "The Norman Conquests" trilogy (1973), "Bedroom Farce" (1975) and "Just Between Ourselves" (1976). These plays focused heavily on marriage in the British middle classes. The only failure during this period was a 1975 musical with Andrew Lloyd Webber, "Jeeves"; even this did little to dent Ayckbourn's career. From the 1980s, Ayckbourn moved away from the recurring theme of marriage to explore other contemporary issues. One example was "Woman in Mind", a play performed entirely from the perspective of a woman going through a nervous breakdown. He also experimented with unconventional ways of writing plays: "Intimate Exchanges", for example, has one beginning and sixteen possible endings, and in "House & Garden", two plays take place simultaneously on two separate stages. He also diversified into children's theatre, such as "Mr A's Amazing Maze Plays" and musical plays, such as "By Jeeves" (a more successful rewrite of the original "Jeeves").
With a résumé of over seventy plays, of which more than forty have played at the National Theatre or in the West End, Alan Ayckbourn is one of England's most successful living playwrights. Despite his success, honours and awards (which include a prestigious Laurence Olivier Award), Alan Ayckbourn remains a relatively anonymous figure, dedicated to regional theatre. Throughout his writing career, all but four of his plays premiered at the Stephen Joseph Theatre in Scarborough in its three different locations. Ayckbourn received the CBE in 1987 and was knighted in the 1997 New Year Honours. It is frequently claimed (but not proved) that Alan Ayckbourn is the most performed living English playwright, and the second most performed of all time, after Shakespeare. Although Ayckbourn's plays no longer dominate the theatrical scene on the scale of his earlier works, he continues to write. Among major success has been "Private Fears in Public Places", which had a hugely successful Off-Broadway run at 59E59 Theaters and, in 2006, was made into a film, "Cœurs", directed by Alain Resnais. After Ayckbourn suffered a stroke, there was uncertainty as to whether he could continue to write. The play that premiered immediately after his stroke, "If I Were You", had been written before his illness; the first play written afterwards, "Life and Beth", premiered in the summer of 2008. Ayckbourn continues to write for the Stephen Joseph Theatre on the invitation of his successor as artistic director, Chris Monks. The first new play under this arrangement, "My Wonderful Day", was performed in October 2009.
Ayckbourn continues to experiment with theatrical form. The play "Roundelay" opened in September 2014; before each performance, members of the audience are invited to extract five coloured ping pong balls from a bag, leaving the order in which each of the five acts is played left to chance, and allowing 120 possible permutations. In "Arrivals and Departures" (2013), the first half of the play is told from the point of view of one character, only for the second half to dramatise the same events from the point of view of another. Many of Ayckbourn's plays, including "Private Fears in Public Places", "Intimate Exchanges", "My Wonderful Day" and "Neighbourhood Watch", have had their New York premiere at 59E59 Theaters as part of the annual Brits Off Broadway Festival. In 2019, Ayckbourn had published his first novel, "The Divide", which had previously been showcased during a reading at the Stephen Joseph Theatre. As a consequence of the Covid lockdown, Ayckbourn's 2020 play, "Anno Domino," was recorded as a radio production, with Ayckbourn and his wife Heather playing all the roles. Similarly, Ayckbourn's Covid-period 2021 play, "The Girl Next Door", was streamed online and made available behind a paywall on the Stephen Joseph Theatre's website.
In 2022, the first Ayckbourn play in around 60 years premiered in a venue other than Scarborough: "All Lies" at the Old Laundry in Bowness-on-Windermere. Directing. Although Ayckbourn is best known as a writer, it is said that he only spends 10% of his time writing plays. Most of the remaining time is spent directing. Ayckbourn began directing at the Scarborough Library Theatre in 1961, with a production of "Gaslight" by Patrick Hamilton. During that year and the next, he directed five other plays in Scarborough and, after transferring to the Victoria Theatre, in 1963 directed a further six plays. Between 1964 and 1967, much of his time was taken up by various productions of his early successes, "Mr. Whatnot" and "Relatively Speaking" and he directed only one play, "The Sparrow", which he wrote and which was later withdrawn. In 1968, he resumed directing plays regularly, mostly at Scarborough. At this time he also worked as a radio drama producer for the BBC, based in Leeds. At first, his directing career was kept separate from his writing career. It was not until 1963 that Ayckbourn directed a play of his own (a revival of "Standing Room Only") and 1967 before he directed a premiere of his own ("The Sparrow"). The London premieres remained in the hands of other directors for longer; the first of his own plays to be directed by him in London was "Bedroom Farce," in 1977.
After the death of Stephen Joseph in 1967, the Director of Productions was appointed on an annual basis. Ayckbourn was offered the position in 1969 and 1970, succeeding Rodney Wood, but he handed the position over to Caroline Smith in 1971, having spent most that year in the US with "How the Other Half Loves". He became Director of Productions again in 1972 and, on 12 November of that year, he was made the permanent artistic director of the theatre. In mid-1986, Ayckbourn accepted an invitation to work as a visiting director for two years at the National Theatre in London, to form his own company, and perform a play in each of the three auditoria, provided at least one was a new play of his own. He used a stock company that included performers such as Michael Gambon, Polly Adams and Simon Cadell. The three plays became four: "Tons of Money" by Will Evans and Valentine, with adaptations by Ayckbourn (Lyttelton); Arthur Miller's "A View From the Bridge" (Cottesloe); his own play "A Small Family Business" (Olivier) and John Ford's "'Tis Pity She's a Whore" (Olivier again). During this time, Ayckbourn shared his role of artistic director of the Stephen Joseph Theatre with Robin Herford and returned in 1987 to direct the premiere of "Henceforward...".
He announced in 1999 that he would step back from directing the work of other playwrights, to concentrate on his own plays, the last one being Rob Shearman's "Knights in Plastic Armour" in 1999; he made one exception in 2002, when he directed the world premiere of Tim Firth's "The Safari Party". In 2002, following a dispute over the Duchess Theatre's handling of "Damsels in Distress", Ayckbourn sharply criticised both this and the West End's treatment of theatre in general and, in particular, their casting of celebrities. Although he did not explicitly say he would boycott the West End, he did not return to direct in there again until 2009, with a revival of "Woman in Mind". He did, however, allow other West End producers to revive "Absurd Person Singular" in 2007 and "The Norman Conquests" in 2008. Ayckbourn suffered a stroke in February 2006 and returned to work in September; the premiere of his 70th play "If I Were You" at the Stephen Joseph Theatre came the following month. He announced in June 2007 that he would retire as artistic director of the Stephen Joseph Theatre after the 2008 season. His successor, Chris Monks, took over at the start of the 2009–2010 season but Ayckbourn remained to direct premieres and revivals of his work at the theatre, beginning with "How the Other Half Loves" in June 2009.
In March 2010, he directed an in-the-round revival of his play "Taking Steps" at the Orange Tree Theatre, winning universal press acclaim. In July 2014, Ayckbourn directed a musical adaptation of "The Boy Who Fell into A Book", with musical adaptation and lyrics by Paul James and music by Eric Angus and Cathy Shostak. The show ran in The Stephen Joseph Theatre and received critical acclaim. Honours and awards. Ayckbourn also sits on the Council of the Society of Authors. He is also a longtime patron of Next Stage Theatre Company, an amateur theatre company based in Bath. Works. One-act plays. Alan Ayckbourn has written eight one-act plays. Five of them ("Mother Figure", "Drinking Companion", "Between Mouthfuls", "Gosforth's Fete" and "Widows Might") were written for "Confusions", first performed in 1974. The other three one-act plays are: Film adaptations of Ayckbourn plays. Plays adapted as films include:
Alpha Centauri Alpha Centauri (, α Cen, or Alpha Cen) is a triple star system in the southern constellation of Centaurus. It consists of three stars: Rigil Kentaurus (), Toliman (), and Proxima Centauri (). Proxima Centauri is the closest star to the Sun at 4.2465 light-years (ly) which is 1.3020 pc. Rigil Kentaurus and Toliman are Sun-like stars (class G and K, respectively) that together form the binary star system . To the naked eye, these two main components appear to be a single star with an apparent magnitude of −0.27. It is the brightest star in the constellation and the third-brightest in the night sky, outshone by only Sirius and Canopus. Rigil Kentaurus has 1.1 times the mass () and 1.5 times the luminosity of the Sun (), while Toliman is smaller and cooler, at and less than . The pair orbit around a common centre with an orbital period of 79 years. Their elliptical orbit is eccentric, so that the distance between A and B varies from 35.6 astronomical units (AU), or about the distance between Pluto and the Sun, to or about the distance between Saturn and the Sun. One astronomical unit is the distance from Earth to the Sun, 150 million kilometers.
Proxima Centauri is a small faint red dwarf (class M). Though not visible to the naked eye, Proxima Centauri is the closest star to the Sun at a distance of , slightly closer than . Currently, the distance between Proxima Centauri and is about , equivalent to about 430 times the radius of Neptune's orbit. Proxima Centauri has one confirmed planet: Proxima b, an Earth-sized planet in the habitable zone (though it is unlikely to be habitable), one candidate planet, Proxima d, sub-Earth which orbits very closely to the star, and the controversial Proxima c, a mini-Neptune astronomical units away. Rigil Kentaurus may have a Neptune-sized planet in the habitable zone, though it is not yet known with certainty to be planetary in nature and could be an artifact of the discovery mechanism. Toliman has no known planets. Etymology and nomenclature. α Centauri (Latinised to Alpha Centauri) is the system's designation given by J. Bayer in 1603. It belongs to the constellation Centaurus, named after the part human, part horse creature in Greek mythology; Heracles accidentally wounded the centaur and placed him in the sky after his death. Alpha Centauri marks the right front hoof of the Centaur. The common name Rigil Kentaurus is a Latinisation of the Arabic translation "Rijl al-Qinṭūrus," meaning "the Foot of the Centaur". "Qinṭūrus" is the Arabic transliteration of the Greek (Kentaurus). The name is frequently abbreviated to Rigil Kent () or even Rigil, though the latter name is better known for Rigel ( Orionis).
An alternative name found in European sources, Toliman, is an approximation of the Arabic "aẓ-Ẓalīmān" (in older transcription, "aṭ-Ṭhalīmān"), meaning 'the (two male) Ostriches', an appellation Zakariya al-Qazwini had applied to the pair of stars Lambda and Mu Sagittarii; it was often not clear on old star maps which name was intended to go with which star (or stars), and the referents changed over time. The name Toliman originates with Jacobus Golius' 1669 edition of Al-Farghani's "Compendium". Tolimân is Golius' Latinisation of the Arabic name "the ostriches", the name of an asterism of which Alpha Centauri formed the main star. was discovered in 1915 by Robert T. A. Innes, who suggested that it be named Proxima Centaurus, . The name Proxima Centauri later became more widely used and is now listed by the International Astronomical Union (IAU) as the approved proper name; it is frequently abbreviated to Proxima. In 2016, the Working Group on Star Names of the IAU, having decided to attribute proper names to individual component stars rather than to multiple systems, approved the name Rigil Kentaurus () as being restricted to and the name Proxima Centauri () for On 10 August 2018, the IAU approved the name Toliman () for
Other names. During the 19th century, the northern amateur popularist E.H. Burritt used the now-obscure name Bungula (). Its origin is not known, but it may have been coined from the Greek letter beta () and Latin 'hoof', originally for Beta Centauri (the other hoof). In Chinese astronomy, "Nán Mén", meaning Southern Gate, refers to an asterism consisting of Alpha Centauri and Epsilon Centauri. Consequently, the Chinese name for Alpha Centauri itself is "Nán Mén Èr", the Second Star of the Southern Gate. To the Indigenous Boorong people of northwestern Victoria in Australia, Alpha Centauri and Beta Centauri are Bermbermgle, two brothers noted for their courage and destructiveness, who speared and killed Tchingal "The Emu" (the Coalsack Nebula). The form in Wotjobaluk is Bram-bram-bult. Observation. To the naked eye, appears to be a single star, the brightest in the southern constellation of Centaurus. Their apparent angular separation varies over about 80 years between 2 and 22 arcseconds (the naked eye has a resolution of 60 arcsec), but through much of the orbit, both are easily resolved in binoculars or small telescopes. At −0.27 apparent magnitude (combined for A and B magnitudes ), Alpha Centauri is a first-magnitude star and is fainter only than Sirius and Canopus. It is the outer star of The Pointers or The Southern Pointers, so called because the line through Beta Centauri (Hadar/Agena), some 4.5° west, points to the constellation Crux—the Southern Cross. The Pointers easily distinguish the true Southern Cross from the fainter asterism known as the False Cross.
South of about 29° South latitude, is circumpolar and never sets below the horizon. North of about 29° N latitude, Alpha Centauri never rises. Alpha Centauri lies close to the southern horizon when viewed from latitude 29° N to the equator (close to Hermosillo and Chihuahua City in Mexico; Galveston, Texas; Ocala, Florida; and Lanzarote, the Canary Islands of Spain), but only for a short time around its culmination. The star culminates each year at local midnight on 24 April and at local 9 p.m. on 8 June. As seen from Earth, Proxima Centauri is 2.2° southwest from this distance is about four times the angular diameter of the Moon. Proxima Centauri appears as a deep-red star of a typical apparent magnitude of 11.1 in a sparsely populated star field, requiring moderately sized telescopes to be seen. Listed as V645 Cen in the "General Catalogue of Variable Stars", version 4.2, this UV Ceti star or "flare star" can unexpectedly brighten rapidly by as much as 0.6 magnitude at visual wavelengths, then fade after only a few minutes. Some amateur and professional astronomers regularly monitor for outbursts using either optical or radio telescopes. In August 2015, the largest recorded flares of the star occurred, with the star becoming 8.3 times brighter than normal on 13 August, in the B band (blue light region).
Observational history. Alpha Centauri is listed in the 2nd century star catalog appended to Ptolemy's "Almagest". Ptolemy gave its ecliptic coordinates, but texts differ as to whether the ecliptic latitude reads or . (Presently the ecliptic latitude is , but it has decreased by a fraction of a degree since Ptolemy's time due to proper motion.) In Ptolemy's time, Alpha Centauri was visible from Alexandria, Egypt, at but, due to precession, its declination is now , and it can no longer be seen at that latitude. English explorer Robert Hues brought Alpha Centauri to the attention of European observers in his 1592 work "Tractatus de Globis", along with Canopus and Achernar, noting: The binary nature of Alpha Centauri AB was recognized in December 1689 by Jean Richaud, while observing a passing comet from his station in Puducherry. Alpha Centauri was only the third binary star to be discovered, preceded by Mizar AB and Acrux. The large proper motion of Alpha Centauri AB was discovered by Manuel John Johnson, observing from Saint Helena, who informed Thomas Henderson at the Royal Observatory, Cape of Good Hope of it. The parallax of Alpha Centauri was subsequently determined by Henderson from many exacting positional observations of the AB system between April 1832 and May 1833. He withheld his results, however, because he suspected they were too large to be true, but eventually published them in 1839 after Bessel released his own accurately determined parallax for in 1838. For this reason, Alpha Centauri is sometimes considered as the second star to have its distance measured because Henderson's work was not fully acknowledged at first. (The distance of Alpha Centauri from the Earth is now reckoned at 4.396 light-years or .)
John Herschel made the first micrometrical observations in 1834. Since the early 20th century, measures have been made with photographic plates. By 1926, William Stephen Finsen calculated the approximate orbit elements close to those now accepted for this system. All future positions are now sufficiently accurate for visual observers to determine the relative places of the stars from a binary star ephemeris. Others, like D. Pourbaix (2002), have regularly refined the precision of new published orbital elements. Robert T. A. Innes discovered Proxima Centauri in 1915 by blinking photographic plates taken at different times during a proper motion survey. These showed large proper motion and parallax similar in both size and direction to those of which suggested that Proxima Centauri is part of the system and slightly closer to Earth than . As such, Innes concluded that Proxima Centauri was the closest star to Earth yet discovered. Location and motion. Alpha Centauri may be inside the G-cloud of the Local Bubble, and its nearest known system is the binary brown dwarf system Luhman 16, at distance.
Kinematics. All components of display significant proper motion against the background sky. Over centuries, this causes their apparent positions to slowly change. Proper motion was unknown to ancient astronomers. Most assumed that the stars were permanently fixed on the celestial sphere, as stated in the works of the philosopher Aristotle. In 1718, Edmond Halley found that some stars had significantly moved from their ancient astrometric positions. In the 1830s, Thomas Henderson discovered the true distance to by analysing his many astrometric mural circle observations. He then realised this system also likely had a high proper motion. In this case, the apparent stellar motion was found using Nicolas Louis de Lacaille's astrometric observations of 1751–1752, by the observed differences between the two measured positions in different epochs. Calculated proper motion of the centre of mass for is about 3620 mas/y (milliarcseconds per year) toward the west and 694 mas/y toward the north, giving an overall motion of 3686 mas/y in a direction 11° north of west. The motion of the centre of mass is about 6.1 arcmin each century, or 1.02° each millennium. The speed in the western direction is and in the northerly direction . Using spectroscopy the mean radial velocity has been determined to be around towards the Solar System. This gives a speed with respect to the Sun of , very close to the peak in the distribution of speeds of nearby stars.
Since is almost exactly in the plane of the Milky Way as viewed from Earth, many stars appear behind it. In early May 2028, will pass between the Earth and a distant red star, when there is a 45% probability that an Einstein ring will be observed. Other conjunctions will also occur in the coming decades, allowing accurate measurement of proper motions and possibly giving information on planets. Predicted future changes. Based on the system's common proper motion and radial velocities, will continue to change its position in the sky significantly and will gradually brighten. For example, in about 6,200 CE, α Centauri's true motion will cause an extremely rare first-magnitude stellar conjunction with Beta Centauri, forming a brilliant optical double star in the southern sky. It will then pass just north of the Southern Cross or Crux, before moving northwest and up towards the present celestial equator and away from the galactic plane. By about 26,700 CE, in the present-day constellation of Hydra, will reach perihelion at away, though later calculations suggest that this will occur in 27,000 AD. At its nearest approach, α Centauri will attain a maximum apparent magnitude of −0.86, comparable to present-day magnitude of Canopus, but it will still not surpass that of Sirius, which will brighten incrementally over the next 60,000 years, and will continue to be the brightest star as seen from Earth (other than the Sun) for the next 210,000 years.
Stellar system. Alpha Centauri is a triple star system, with its two main stars, A and B, together comprising a binary component. The "AB" designation, or older "A×B", denotes the mass centre of a main binary system relative to companion star(s) in a multiple star system. "AB-C" refers to the component of Proxima Centauri in relation to the central binary, being the distance between the centre of mass and the outlying companion. Because the distance between Proxima (C) and either of Alpha Centauri A or B is similar, the AB binary system is sometimes treated as a single gravitational object. Orbital properties. The A and B components of Alpha Centauri have an orbital period of 79.762 years. Their orbit is moderately eccentric, as it has an eccentricity of almost 0.52; their closest approach or periastron is , or about the distance between the Sun and Saturn; and their furthest separation or apastron is , about the distance between the Sun and Pluto. The most recent periastron was in August 1955 and the next will occur in May 2035; the most recent apastron was in May 1995 and will next occur in 2075.
Viewed from Earth, the apparent orbit of A and B means that their separation and position angle (PA) are in continuous change throughout their projected orbit. Observed stellar positions in 2019 are separated by 4.92 arcsec through the PA of 337.1°, increasing to 5.49 arcsec through 345.3° in 2020. The closest recent approach was in February 2016, at 4.0 arcsec through the PA of 300°. The observed maximum separation of these stars is about 22 arcsec, while the minimum distance is 1.7 arcsec. The widest separation occurred during February 1976, and the next will be in January 2056. Alpha Centauri C is about from Alpha Centauri AB, equivalent to about 5% of the distance between Alpha Centauri AB and the Sun. Until 2017, measurements of its small speed and its trajectory were of too little accuracy and duration in years to determine whether it is bound to Alpha Centauri AB or unrelated. Radial velocity measurements made in 2017 were precise enough to show that Proxima Centauri and Alpha Centauri AB are gravitationally bound. The orbital period of Proxima Centauri is approximately years, with an eccentricity of 0.5, much more eccentric than Mercury's. Proxima Centauri comes within of AB at periastron, and its apastron occurs at .
Physical properties. Asteroseismic studies, chromospheric activity, and stellar rotation (gyrochronology) are all consistent with the Alpha Centauri system being similar in age to, or slightly older than, the Sun. Asteroseismic analyses that incorporate tight observational constraints on the stellar parameters for the Alpha Centauri stars have yielded age estimates of Gyr, Gyr, 6.4 Gyr, and Gyr. Age estimates for the stars based on chromospheric activity (Calcium H & K emission) yield whereas gyrochronology yields Gyr. Stellar evolution theory implies both stars are slightly older than the Sun at 5 to 6 billion years, as derived by their mass and spectral characteristics. From the orbital elements, the total mass of Alpha Centauri AB is about – or twice that of the Sun. The average individual stellar masses are about and , respectively, though slightly different masses have also been quoted in recent years, such as and , totaling . Alpha Centauri A and B have absolute magnitudes of +4.38 and +5.71, respectively.
Alpha Centauri AB System. Alpha Centauri A. Alpha Centauri A, also known as Rigil Kentaurus, is the principal member, or primary, of the binary system. It is a solar-like main-sequence star with a similar yellowish colour, whose stellar classification is spectral type G2-V; it is about 10% more massive than the Sun, with a radius about 22% larger. When considered among the individual brightest stars in the night sky, it is the fourth-brightest at an apparent magnitude of +0.01, being slightly fainter than Arcturus at an apparent magnitude of −0.05. The type of magnetic activity on Alpha Centauri A is comparable to that of the Sun, showing coronal variability due to star spots, as modulated by the rotation of the star. However, since 2005 the activity level has fallen into a deep minimum that might be similar to the Sun's historical Maunder Minimum. Alternatively, it may have a very long stellar activity cycle and is slowly recovering from a minimum phase. Alpha Centauri B. Alpha Centauri B, also known as Toliman, is the secondary star of the binary system. It is a main-sequence star of spectral type K1-V, making it more an orange colour than Alpha Centauri A; it has around 90% of the mass of the Sun and a 14% smaller diameter. Although it has a lower luminosity than A, Alpha Centauri B emits more energy in the X-ray band. Its light curve varies on a short time scale, and there has been at least one observed flare. It is more magnetically active than Alpha Centauri A, showing a cycle of compared to 11 years for the Sun, and has about half the minimum-to-peak variation in coronal luminosity of the Sun. This cycle was recently re-estimated based on more than 20 years of high-resolution spectroscopic observations of the CaIIH&K lines showing a cycle of . Alpha Centauri B has an apparent magnitude of +1.35, slightly dimmer than Mimosa.
Alpha Centauri C. Alpha Centauri C, better known as Proxima Centauri, is a small main-sequence red dwarf of spectral class M6-Ve. It has an absolute magnitude of +15.60, over 20,000 times fainter than the Sun. Its mass is calculated to be . It is the closest star to the Sun but is too faint to be visible to the naked eye. Planetary system. The Alpha Centauri system as a whole has two confirmed planets, both of them around Proxima Centauri. While other planets have been claimed to exist around all of the stars, none of the discoveries have been confirmed. Planets of Proxima Centauri. Proxima Centauri b is a terrestrial planet discovered in 2016 by astronomers at the European Southern Observatory (ESO). It has an estimated minimum mass of 1.17 (Earth masses) and orbits approximately 0.049 AU from Proxima Centauri, placing it in the star's habitable zone. The discovery of Proxima Centauri c was formally published in 2020 and could be a super-Earth or mini-Neptune. It has a mass of roughly 7 and orbits about from Proxima Centauri with a period of . In June 2020, a possible direct imaging detection of the planet hinted at the presence of a large ring system. However, a 2022 study disputed the existence of this planet.
A 2020 paper refining Proxima b's mass excludes the presence of extra companions with masses above at periods shorter than 50 days, but the authors detected a radial-velocity curve with a periodicity of 5.15 days, suggesting the presence of a planet with a mass of about . This planet, Proxima Centauri d, was detected in 2022. Planets of Alpha Centauri A. In 2021, a candidate planet named Candidate 1 (or C1) was detected around Alpha Centauri A, thought to orbit at approximately with a period of about one year, and to have a mass between that of Neptune and one-half that of Saturn, though it may be a dust disk or an artifact. The possibility of C1 being a background star has been ruled out. If this candidate is confirmed, the temporary name C1 will most likely be replaced with the scientific designation Alpha Centauri Ab in accordance with current naming conventions. GO Cycle 1 observations are planned for the James Webb Space Telescope (JWST) to search for planets around Alpha Centauri A, as well as observations of Epsilon Muscae. The coronographic observations, which occurred on July 26 and 27, 2023, were failures, though there are follow-up observations in March 2024. Pre-launch estimates predicted that JWST will be able to find planets with a radius of 5 at . Multiple observations every 3–6 months could push the limit down to 3 . Post-launch estimates based on observations of HIP 65426 b find that JWST will be able to find planets even closer to Alpha Centauri A and could find a 5 planet at . Candidate 1 has an estimated radius between and orbits at . It is therefore likely within the reach of JWST observations.
Planets of Alpha Centauri B. The first claim of a planet around Alpha Centauri B was that of Alpha Centauri Bb in 2012, which was proposed to be an Earth-mass planet in a 3.2-day orbit. This was refuted in 2015 when the apparent planet was shown to be an artifact of the way the radial velocity data was processed. A search for transits of planet Bb was conducted with the Hubble Space Telescope from 2013 to 2014. This search detected one potential transit-like event, which could be associated with a different planet with a radius around . This planet would most likely orbit Alpha Centauri B with an orbital period of 20.4 days or less, with only a 5% chance of it having a longer orbit. The median of the likely orbits is 12.4 days. Its orbit would likely have an eccentricity of 0.24 or less. It could have lakes of molten lava and would be far too close to Alpha Centauri B to harbour life. If confirmed, this planet might be called . However, the name has not been used in the literature, as it is not a claimed discovery.
Hypothetical planets. Additional planets may exist in the Alpha Centauri system, either orbiting Alpha Centauri A or Alpha Centauri B individually, or in large orbits around Alpha Centauri AB. Because both stars are fairly similar to the Sun (for example, in age and metallicity), astronomers have been especially interested in making detailed searches for planets in the Alpha Centauri system. Several established planet-hunting teams have used various radial velocity or star transit methods in their searches around these two bright stars. All the observational studies have so far failed to find evidence for brown dwarfs or gas giants. In 2009, computer simulations showed that a planet might have been able to form near the inner edge of Alpha Centauri B's habitable zone, which extends from from the star. Certain special assumptions, such as considering that the Alpha Centauri pair may have initially formed with a wider separation and later moved closer to each other (as might be possible if they formed in a dense star cluster), would permit an accretion-friendly environment farther from the star. Bodies around Alpha Centauri A would be able to orbit at slightly farther distances due to its stronger gravity. In addition, the lack of any brown dwarfs or gas giants in close orbits around Alpha Centauri make the likelihood of terrestrial planets greater than otherwise. A theoretical study indicates that a radial velocity analysis might detect a hypothetical planet of in Alpha Centauri B's habitable zone.
Radial velocity measurements of Alpha Centauri B made with the High Accuracy Radial Velocity Planet Searcher spectrograph were sufficiently sensitive to detect a planet within the habitable zone of the star (i.e. with an orbital period P = 200 days), but no planets were detected. Current estimates place the probability of finding an Earth-like planet around Alpha Centauri at roughly 75%. The observational thresholds for planet detection in the habitable zones by the radial velocity method are currently (2017) estimated to be about for Alpha Centauri A, for Alpha Centauri B, and for Proxima Centauri. Early computer-generated models of planetary formation predicted the existence of terrestrial planets around both Alpha Centauri A and B, but most recent numerical investigations have shown that the gravitational pull of the companion star renders the accretion of planets difficult. Despite these difficulties, given the similarities to the Sun in spectral types, star type, age and probable stability of the orbits, it has been suggested that this stellar system could hold one of the best possibilities for harbouring extraterrestrial life on a potential planet.
In the Solar System, it was once thought that Jupiter and Saturn were probably crucial in perturbing comets into the inner Solar System, providing the inner planets with a source of water and various other ices. However, since isotope measurements of the deuterium to hydrogen (D/H) ratio in comets Halley, Hyakutake, Hale–Bopp, 2002T7, and Tuttle yield values approximately twice that of Earth's oceanic water, more recent models and research predict that less than 10% of Earth's water was supplied from comets. In the system, Proxima Centauri may have influenced the planetary disk as the system was forming, enriching the area around Alpha Centauri with volatile materials. This would be discounted if, for example, happened to have gas giants orbiting (or vice versa), or if and B themselves were able to perturb comets into each other's inner systems, as Jupiter and Saturn presumably have done in the Solar System. Such icy bodies probably also reside in Oort clouds of other planetary systems. When they are influenced gravitationally by either the gas giants or disruptions by passing nearby stars, many of these icy bodies then travel star-wards. Such ideas also apply to the close approach of Alpha Centauri or other stars to the Solar system, when, in the distant future, the Oort Cloud might be disrupted enough to increase the number of active comets.
To be in the habitable zone, a planet around Alpha Centauri A would have an orbital radius of between about 1.2 and so as to have similar planetary temperatures and conditions for liquid water to exist. For the slightly less luminous and cooler , the habitable zone is between about 0.7 and . With the goal of finding evidence of such planets, both Proxima Centauri and were among the listed "Tier-1" target stars for NASA's Space Interferometry Mission (S.I.M.). Detecting planets as small as three Earth-masses or smaller within two AU of a "Tier-1" target would have been possible with this new instrument. The S.I.M. mission, however, was cancelled due to financial issues in 2010. Circumstellar discs. Based on observations between 2007 and 2012, a study found a slight excess of emissions in the 24 μm (mid/far-infrared) band surrounding , which may be interpreted as evidence for a sparse circumstellar disc or dense interplanetary dust. The total mass was estimated to be between to the mass of the Moon, or 10–100 times the mass of the Solar System's zodiacal cloud. If such a disc existed around both stars, disc would likely be stable to and would likely be stable to This would put A's disc entirely within the frost line, and a small part of B's outer disc just outside.
View from this system. The sky from would appear much as it does from the Earth, except that Centaurus's brightest star, being itself, would be absent from the constellation. The Sun would appear as a white star of apparent magnitude +0.5, roughly the same as the average brightness of Betelgeuse from Earth. It would be at the antipodal point of current right ascension and declination, at (2000), in eastern Cassiopeia, easily outshining all the rest of the stars in the constellation. With the placement of the Sun east of the magnitude 3.4 star Epsilon Cassiopeiae, nearly in front of the Heart Nebula, the "W" line of stars of Cassiopeia would have a "/W" shape. Other nearby stars' placements may be affected somewhat drastically. Sirius, at 9.2 light years away from the system, would still be the brightest star in the night sky, with a magnitude of -1.2, but would be located in Orion less than a degree away from Betelgeuse. Procyon, which would also be at a slightly further distance than from the Sun, would move to outshine Pollux in the middle of Gemini.
A planet around either or B would see the other star as a very bright secondary. For example, an Earth-like planet at from (with a revolution period of 1.34 years) would get Sun-like illumination from its primary, and would appear 5.7–8.6 magnitudes dimmer (−21.0 to −18.2), 190–2,700 times dimmer than but still 150–2,100 times brighter than the full Moon. Conversely, an Earth-like planet at from (with a revolution period of 0.63 years) would get nearly Sun-like illumination from its primary, and would appear 4.6–7.3 magnitudes dimmer (−22.1 to −19.4), 70 to 840 times dimmer than but still 470–5,700 times brighter than the full Moon. Proxima Centauri would appear dim as one of many stars, being magnitude 4.5 at its current distance, and magnitude 2.6 at periastron. Future exploration. Alpha Centauri is a first target for crewed or robotic interstellar exploration. Using current spacecraft technologies, crossing the distance between the Sun and Alpha Centauri would take several millennia, though the possibility of nuclear pulse propulsion or laser light sail technology, as considered in the Breakthrough Starshot program, could make the journey to Alpha Centauri in 20 years. An objective of such a mission would be to make a fly-by of, and possibly photograph, planets that might exist in the system. The existence of Proxima Centauri b, announced by the European Southern Observatory (ESO) in August 2016, would be a target for the Starshot program.
NASA released a mission concept in 2017 that would send a spacecraft to Alpha Centauri in 2069, scheduled to coincide with the 100th anniversary of the first crewed lunar landing in 1969, Even at speed 10% of the speed of light (about 108 million km/h), which NASA experts say may be possible, it would take a spacecraft 44 years to reach the constellation, by the year 2113, and would take another 4 years for a signal, by the year 2117 to reach Earth. The concept received no further funding or development. In culture. Alpha Centauri has been recognized and associated throughout history, particularly in the Southern Hemisphere. Polynesians have been using Alpha Centauri for their star navigation and have called it Kamailehope. In the Ngarrindjeri culture of Australia, Alpha Centauri represents with Beta Centauri two sharks chasing a stingray, the Southern Cross, and in Incan culture it with Beta Centauri form the eyes of a llama-shaped dark constellation embedded in the band of stars that the visible Milky Way forms in the sky. In ancient Egypt it was also revered and in China it is known as part of the South Gate asterism. The Sagan Planet Walk in Ithaca, New York, is a walkable scale model of the solar system. An obelisk representing the scaled position of Alpha Centauri has been added at ʻImiloa Astronomy Center in Hawaii.
Amiga Amiga is a family of personal computers produced by Commodore from 1985 until the company's bankruptcy in 1994, with production by others afterward. The original model is one of a number of mid-1980s computers with 16-bit or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. These include the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. The Amiga differs from its contemporaries through custom hardware to accelerate graphics and sound, including sprites, a blitter, and four channels of sample-based audio. It runs a pre-emptive multitasking operating system called AmigaOS, with a desktop environment called Workbench. The Amiga 1000, based on the Motorola 68000 microprocessor, was released in July 1985. Production problems kept it from becoming widely available until early 1986. While early advertisements cast the computer as an all-purpose business machine, especially with the Sidecar IBM PC compatibility add-on, the Amiga was most commercially successful as a home computer with a range of video games and creative software. The bestselling model, the Amiga 500, was introduced in 1987 along with the more expandable Amiga 2000. The 1990 Amiga 3000 includes a minor update to the graphics hardware via the Enhanced Chip Set, also used in subsequent models.
The Amiga established a niche in audio and multimedia. The first music tracker was written for the Amiga, and it became a popular platform for music creation. The 3D rendering packages LightWave 3D, Imagine, and Traces (a predecessor to Blender) originated on the system. The 1990 third-party Video Toaster made the Amiga a comparatively low cost option for video production. In later years, the Amiga started losing market share to IBM PC compatibles and video game consoles, eventually leading to Commodore's bankruptcy in 1994 and the end of Amiga. Commodore is estimated to have sold 4.85 million Amigas. Various groups have since released spiritual successors. History. Concept and early development. Jay Miner joined Atari, Inc. in the 1970s and led development of the Atari Video Computer System's graphics and sound chip, the Television Interface Adaptor. When complete, the team began developing a much more sophisticated set of chips, CTIA, ANTIC and POKEY, that formed the basis of the Atari 8-bit computers. With the 8-bit line's launch in 1979, the team once again started looking at a next generation chipset. Nolan Bushnell had sold the company to Warner Communications in 1978, and the new management was much more interested in the existing lines than development of new products that might cut into their sales. Miner wanted to start work with the new Motorola 68000, but management was only interested in another 6502 based system. Miner left the company, and, for a time, the industry.
In 1979, Larry Kaplan left Atari and founded Activision. In 1982, Kaplan was approached by a number of investors who wanted to develop a new game platform. Kaplan hired Miner to run the hardware side of the newly formed company, "Hi-Toro". The system was code-named "Lorraine" in keeping with Miner's policy of giving systems female names, in this case the company president's wife, Lorraine Morse. When Kaplan left the company late in 1982, Miner was promoted to head engineer and the company relaunched as Amiga Corporation. The Amiga hardware was designed by Miner, RJ Mical, and Dale Luck. A breadboard prototype for testing and development was largely completed by late 1983, and shown at the January 1984 Consumer Electronics Show (CES). A further developed version of the system was demonstrated at the June 1984 CES and shown to many companies in hopes of garnering further funding, but found little interest in a market that was in the final stages of the video game crash of 1983. In March, Atari expressed a tepid interest in Lorraine for its potential use in a games console or home computer tentatively known as the . The talks were progressing slowly, and Amiga was running out of money. A temporary arrangement in June led to a $500,000 loan from Atari to Amiga to keep the company going. The terms required the loan to be repaid at the end of the month, otherwise Amiga would forfeit the Lorraine design to Atari.
Commodore. By the end of the video game crash of 1983, Warner was desperate to sell Atari. In January 1984, Jack Tramiel resigned from Commodore, taking some Commodore employees to his new company, Tramel Technology. This included a number of the senior technical staff, where they began development of a new 68000-based machine. In June, Tramiel arranged a no-cash deal to take over Atari, reforming Tramel Technology as Atari Corporation. Commodore was left without a workable path to creating a next-generation home computer, and it offered to fund Amiga development. The two companies were initially arranging a license agreement before Commodore offered to purchase Amiga outright. By late 1984, the prototype breadboard chipset had successfully been turned into integrated circuits, and the system hardware was being readied for production. At this time, the operating system was not ready, and led to a deal to port TRIPOS. TRIPOS was a multitasking system written in BCPL during the 1970s for the PDP-11 minicomputer. This early version was known as AmigaDOS and the GUI as Workbench. The BCPL parts were later rewritten in the C language, and the entire system became AmigaOS.
The system was enclosed in a pizza-box form factor case. A late change was the introduction of vertical supports on either side of the case to provide a "garage" under the main section of the system where the keyboard could be stored. Launch. The first model was announced in 1985 as simply "The Amiga from Commodore", later to be retroactively dubbed the Amiga 1000. They were first offered for sale in August, but by October only 50 had been built, all of which were used by Commodore. Machines only began to arrive in quantity in mid-November, meaning they missed the Christmas buying rush. By the end of the year, they had sold 35,000 machines, and severe cashflow problems made the company pull out of the January 1986 CES. Bad or entirely missing marketing, forcing the development team to move to the east coast, notorious stability problems and other blunders limited sales in early 1986 to between 10,000 and 15,000 units a month. 120,000 units were reported as having been sold from the machine's launch up to the end of 1986.
Later models. In late 1985, Thomas Rattigan was promoted to COO of Commodore, and then to CEO in February 1986. He immediately implemented an ambitious plan that covered almost all of the company's operations. Among these was the long-overdue cancellation of the now outdated PET and VIC-20 lines, as well as a variety of poorly selling Commodore 64 offshoots and the Commodore 900 workstation effort. Another one of the changes was to split the Amiga into two products, a new high-end version of the Amiga aimed at the creative market, and a cost-reduced version that would take over for the Commodore 64 in the low-end market. These new designs were released in 1987 as the Amiga 2000 and Amiga 500, the latter of which went on to widespread success and became their best selling model. Similar high-end/low-end models would make up the Amiga line for the rest of its history; follow-on designs included the Amiga 3000/Amiga 500 Plus/Amiga 600, and the Amiga 4000/Amiga 1200. These models incorporated a series of technical upgrades known as the ECS and AGA, which added higher resolution displays among many other improvements and simplifications.
The Amiga line sold an estimated 4,910,000 machines over its lifetime. The machines were most popular in the UK and Germany, with about 1.5 million sold in each country, and sales in the high hundreds of thousands in other European nations. The machine was less popular in North America, where an estimated 700,000 were sold. In the United States, the Amiga found a niche with enthusiasts and in vertical markets for video processing and editing. In Europe, it was more broadly popular as a home computer and often used for video games. Beginning in 1988 it overlapped with the 16-bit Mega Drive, then the Super Nintendo Entertainment System in the early 1990s. Commodore UK's Kelly Sumner did not see Sega or Nintendo as competitors, but instead credited their marketing campaigns which spent over or for promoting video games as a whole and thus helping to boost Amiga sales. Bankruptcy and aftermath. In spite of his successes in making the company profitable and bringing the Amiga line to market, Rattigan was soon forced out in a power struggle with majority shareholder, Irving Gould. This is widely regarded as the turning point, as further improvements to the Amiga were eroded by rapid improvements in other platforms.
Commodore shut down the Amiga division on April 26, 1994, and filed for bankruptcy three days later. Commodore's assets were purchased by Escom, a German PC manufacturer, who created the subsidiary company Amiga Technologies. They re-released the A1200 and A4000T, and introduced a new 68060 version of the A4000T. Amiga Technologies researched and developed the Amiga Walker prototype. They presented the machine publicly at CeBit, but Escom went bankrupt in 1996. Some Amigas were still made afterwards for the North American market by QuikPak, a small Pennsylvania-based firm who was the manufacturer of Amigas for Escom. After a reported sale to VisCorp fell through, a U.S. Wintel PC manufacturer, Gateway 2000, eventually purchased the Amiga branch and technology in 1997. QuickPak attempted but failed to license Amiga from Gateway and build new models. Gateway was then working on a brand new Amiga platform, likely encouraged by a desire to be independent of Microsoft and Intel. However this did not materialize and in 2000, Gateway sold the Amiga brand to Amiga, Inc., without having released any products. Amiga, Inc. licensed the rights to sell hardware using the AmigaOne brand to Eyetech Group and Hyperion Entertainment. In 2019, Amiga, Inc. sold its intellectual property to Amiga Corporation.
Hardware. The Amiga has a custom chipset consisting of several coprocessors which handle audio, video, and direct memory access independently of the central processing unit (CPU). This architecture gave the Amiga a performance edge over its competitors, particularly for graphics-intensive applications and games. The architecture uses two distinct bus subsystems: the chipset bus and the CPU bus. The chipset bus allows the coprocessors and CPU to address "Chip RAM". The CPU bus provides addressing to conventional RAM, ROM and the Zorro II or Zorro III expansion subsystems. This enables independent operation of the subsystems. The CPU bus can be much faster than the chipset bus. CPU expansion boards may provide additional custom buses. Additionally, "busboards" or "bridgeboards" may provide ISA or PCI buses. Central processing unit. The most popular models from Commodore, including the Amiga 1000, Amiga 500, and Amiga 2000, use the Motorola 68000 as the CPU. From a developer's point of view, the 68000 provides a full suite of 32-bit operations, but the chip can address only 16 MB of physical memory and is implemented using a 16-bit arithmetic logic unit and has a 16-bit external data bus, so 32-bit computations are transparently handled as multiple 16-bit values at a performance cost. The later Amiga 2500 and the Amiga 3000 models use fully 32-bit, 68000-compatible processors from Motorola with improved performance and larger addressing capability.
CPU upgrades were offered by both Commodore and third-party manufacturers. Most Amiga models can be upgraded either by direct CPU replacement or through expansion boards. Such boards often included faster and higher capacity memory interfaces and hard disk controllers. Towards the end of Commodore's time in charge of Amiga development, there were suggestions that Commodore intended to move away from the 68000 series to higher performance RISC processors, such as the PA-RISC. Those ideas were never developed before Commodore filed for bankruptcy. Despite this, third-party manufacturers designed upgrades featuring a combination of 68000 series and PowerPC processors along with a PowerPC native microkernel and software. Later Amiga clones featured PowerPC processors only. Custom chipset. The custom chipset at the core of the Amiga design appeared in three distinct generations, with a large degree of backward-compatibility. The Original Chip Set (OCS) appeared with the launch of the A1000 in 1985. OCS was eventually followed by the modestly improved Enhanced Chip Set (ECS) in 1990 and finally by the partly 32-bit Advanced Graphics Architecture (AGA) in 1992. Each chipset consists of several coprocessors that handle graphics acceleration, digital audio, direct memory access and communication between various peripherals (e.g., CPU, memory and floppy disks). In addition, some models featured auxiliary custom chips that performed tasks such as SCSI control and display de-interlacing.
Graphics. All Amiga systems can display full-screen animated planar graphics with 2, 4, 8, 16, 32, 64 (EHB Mode), or 4096 colors (HAM Mode). Models with the AGA chipset (A1200 and A4000) also have non-EHB 64, 128, 256, and 262144 (HAM8 Mode) color modes and a palette expanded from 4096 to 16.8 million colors. The Amiga chipset can "genlock", which is the ability to adjust its own screen refresh timing to match an incoming NTSC or PAL video signal. When combined with setting transparency, this allows an Amiga to overlay an external video source with graphics. This ability made the Amiga popular for many applications, and provides the ability to do character generation and CGI effects far more cheaply than earlier systems. This ability has been frequently utilized by wedding videographers, TV stations and their weather forecasting divisions (for weather graphics and radar), advertising channels, music video production, and desktop videographers. The NewTek Video Toaster was made possible by the genlock ability of the Amiga.
In 1988, the release of the Amiga A2024 fixed-frequency monochrome monitor with built-in framebuffer and flicker fixer hardware provided the Amiga with a choice of high-resolution graphic modes (1008×800 for NTSC and 1008×1024 for PAL) with 4 Grayscale levels. ReTargetable Graphics. ReTargetable Graphics is an API for device drivers mainly used by 3rd party graphics hardware to interface with AmigaOS via a set of libraries. The software libraries may include software tools to adjust resolution, screen colors, pointers and screenmodes. The standard Intuition interface is limited to display depths of 8 bits, while RTG makes it possible to handle higher depths like 24-bits. Sound. The sound chip, named Paula, supports four PCM sound channels (two for the left speaker and two for the right) with 8-bit resolution for each channel and a 6-bit volume control per channel. The analog output is connected to a low-pass filter, which filters out high-frequency aliasing when the Amiga is using a lower sampling rate (see Nyquist frequency). The brightness of the Amiga's power LED is used to indicate the status of the Amiga's low-pass filter. The filter is active when the LED is at normal brightness, and deactivated when dimmed (or off on older A500 Amigas). On Amiga 1000 (and first Amiga 500 and Amiga 2000 model), the power LED had no relation to the filter's status, and a wire needed to be manually soldered between pins on the sound chip to disable the filter. Paula can read arbitrary waveforms at arbitrary rates and amplitudes directly from the system's RAM, using direct memory access (DMA), making sound playback without CPU intervention possible.
