[Thanksgiving question] Who invented pie and why don't we honor them?
[ "I believe the general consensus is that it was a Greek invention (Aristophanes mentions pastries in The Clouds, so 5th Century BC at least), but the pastry was used to carry and preserve the contents, rather than being designed to be one edible article. The convention of eating the crust came far later during late medieval times in England where the poor would eat the undesirable (and practically inedible) crust. Americans \"refined\" the pie down to sweet pastries only for some odd reason (perhaps a lack of meat available meant filling pastry with fruit was more cost-efficient?). Here is a long article that covers the history of the pie (not in a very well structured order, unfortunately) which uses sources such as; - Oxford English Dictionary, Volume III, 1982 - Pie: A Global History, by Janet Clarkson - The White House Cookbook by Mrs. F.L. Gillette, 1887 _URL_0_ As a Brit, I have to say that everyone should eat a steak pie at least once. There's nothing better than hot steak pie, chips and gravy." ]

Was the common working man in England during the Napoleonic Wars really aware of it? Was it something that people with no direct involvement would have talked about on a daily basis?
[ "Aside from the fact there were several thousand English soldiers from all over the country serving, and at least some of them sending letters home. People of the day who had access to a Newspaper would be able to read about the events in the form of dispatches that were published. For example, after the Battle of Waterloo on June 19th, 1815, Wellington's reports were published in the London Gazette on June 22nd. (edit: 22nd, sorry, not 21st)." ]
[ "The character George in Blackadder III was clownishly stupid, and recognized himself to be so. He knew his mental limitations, but was willing to give anything a try, perpetually failing at the task. George IV was not the same. He was recorded as being a smart student, but tended to fail at the big picture issues and was a public relations nightmare. He received an enormous allowance but managed to spend even more. He had a secret marriage that was not recognized by the establishment, is rumored to have had several mistresses, then put his legal wife on public trial for adultery. \"Gormless\" is not a word that I hear very often in American lingo. To which George would it apply?" ]

Why were the British opposed to the idea of hegemony in Europe, being bought about by Germany in 1914?
[ "Because Britain's Strategy in Europe was to maintain a balance of Power. This can be seen in it's interventions against Napoleon, as well as against Germany in World War 1. Britain entered WWI because Germany violated Belgium's sovereignty. Belgium was a wonderful place to cross the channel from. Britain could fight off France. Britain could fight off Germany. Britain could fight off Spain and France with German Help. Britain could not fight off France and Germany. And so, European Hegemony was terrifying to Britain, because it meant that Britain would be threatened." ]
[ "This question is answered in Dan Carlin's podcast. He explains that France and Germany knew that war was inevitable and both wanted Russia to be their ally. Otto Von Bismarck was successful in allying the new German Empire with Russia, but when he was out of office, Kaiser Wilhelm did not work to keep this alliance. France was able to court the ignored Russia and ally with them. France and Russia had been enemies 100 years prior ( since Napoleon's 1812 Invasion) so the WWI alliance had less to do with historical ties and more to do with France's practical needs." ]

To clarify: It's possible that this would have been illegal in some municipality, but I haven't read anything on it." ]

[European history] How did the fleet led by Christopher Columbus make its return to Spain in 1493?
[ "Columbus actually returned to Europe a different \"way\" than he came -- I mean, he sailed both ways, but on his return route he took a more northerly circular path, to profit from the Gulf Stream current and to avoid the area of calm airs called the Sargasso Sea in the central Atlantic.

What do we know about the Viking exploration of North America? What are the facts? What do we speculate and assume?

[ "I recommend that you ask whether the classic Viking funeral with the burning boat ever occurred. There is plenty of archaeological evidence consisting of gravesites surrounded by stones arranged in the shape of a boat, and there are a few buried vessels used as graves, so the archaeology is good for this sort of grave-reference to ships. The archaeology of a boat burnt off shore is not likely to exist, so one must rely on primary sources. So where did this idea come from? How common was it? And more importantly, how did it evolve over time? There are also cenotaphs, which is a nice topic, and it gives you an opportunity to use a word that rarely enters into everyday conversation. Good luck." ]

Was/Is the role of the "little boats" during operation Dynamo (the evacuation from Dunkirk) overstated?
[ "The popular view of the evacuation from Dunkirk is one of the RN and the \"little ships\" rescuing the BEF from the beaches. Although the RN were heavily involved, the bulk of the vessels used in the evacuation were conventional merchant vessels of all types, cargo ships, ferries and fishing vessels of all types were involved. The larger ships used the docks and then the moles at Dunkirk, then when these were destroyed by bombing, ships' boats collected the men from the open beaches north of the town, and ferried them to the larger vessels. The \"little ships\" were then collected to help in this process of ferrying the men to the larger ships. They were, of course, very important in the morale boosting story post evacuation. The annoying thing (obviously I'm biased) I've found about every single screen/film portrayal of Dunkirk is the ignoring of the role of the civilians in the Merchant Navy in the evacuation! I hope that this new version won't be the same." ]
[ "\"The Battle of Normandy\" or \"Normandy Campaign\" is the most encompassing term, referring to the entire campaign to liberate France from the Germans and establish a foothold for the allies in Western Europe, from June to September 1944. \"The Normandy Invasion\" was the first few weeks of the Battle of Normandy, which resulted in the allied forces taking over Normandy. \"The Normandy Landings\" was the first operation of the Normandy Invasion - the actual landing on the beaches of Normandy - on June 6, 1944. \"D-Day\" is the day of the Normandy Landing - June 6, 1944. Broadly speaking, \"D-Day\" is a military term for a date when an operation is to be initiated." ]

What plans, if any, did the Confederate States of America have - or discuss - for expansion into Latin America?
[ "None that I know of, however, Southerners before the war had long had pipe dreams of an America that would extend to Panama. All of these new territories would be slave states. More realistic were attempts to gain Cuba as a slave state. One southerner, Walker, established a slave country in Nicuragua by an invasion of the sons of Southern slavers. This regime was overthrown quickly. The Slavers tried to strong arm one of the weak antebellum presidents (Pierce or Buchanan, I forgot which) into forcing the \"purchase\" of Cuba via a secret document called the Ostend Manifesto. It would have worked too, if the document wasn't leaked to the public. The Northern states raised holy hell about a new slave state, and one that would be wrangled from another power at that (insert irony about the Spanish-American War here), and thus the Ostend Manifesto was dropped to maintain the peace." ]
[ "You will probably get a lot of differing answers, but at the end of the day it all depends on how you define \"Empire\" and if you include informal Imperialism in this definition. If you are looking for formal Imperialism, it gets a bit easier: The USA was an Empire after the Spanish-American War of 1898, when it acquired Puerto Rico, Cuba, the Philippines and Guam from Spain. Although it has been debated if the Westward Movement could be regarded as Imperialism as well. As you didn't really elaborate on your question, I'll leave it at that for now.

After gaining independence there were struggles to modify laws and provide for a stable structure that enables economic prosperity for the nation.

How did George Washington Carver inventing peanut butter become one of the prototypical "contributions" black people have made to society?
[ "He didn't invent peanut butter. Marcellus Gilmore Edson did." ]
[ "Well we're still feeling the ripple effect from old racism and slavery. Watermelon originally came from South Africa and spread through most of Africa in ancient times. It was the moors who brought watermelon to Europe and early American settlers who brought it here to the USA. When slavery was at its peak, watermelon's popularity in the states also rose dramatically because African slaves would be inclined to have food from their native homeland (them and their ancestors ate watermelon pretty regularly). Proponents of slavery would use the watermelon as an iconic symbol to push their agenda, \"all you need to keep a slave happy is a watermelon, so obviously they are subhuman since us white folks need more than just watermelon to be happy.\" After slavery ended here in the us, there were still plenty of racial overtones that continued on with the watermelon. You are right that it is complete bullshit, one study showed the African Americans only account for 11 percent of watermelon consumed in the us." ]

While the weirdo part is perhaps too harsh (he was committed to his work), he absolutely was a jerk and (probably because of this) was also a bit of a loner. This has led some people (including some historians who should know better) to try to explain these things by invoking things like Newton having autism/aspergers, or being gay. He certainly may have had autism or aspergers, but there's no way for us to know. Similarly, he certainly may have been gay. He definitely had no interest in women. But as far as I know there is no actual evidence pointing to Newton being gay, or having a sexual relationship with Fatio." ]

The Council of Nicaea in 325 enacted a series of canon laws, one of which was to ban self castration. How big an issue was this for it to be one of the few things on their agenda?!
[ "I don't know how popular it was, but I know that [Origen](_URL_0_), a prominent Christian leader of the previous century, had castrated himself. So, it would definitely have been on the minds of the Council. As for why, I can see three reasons: * To promote chastity. Christian teaching then saw sin even more seriously than many do now; churches usually required years of public humiliation before restoring someone to communion after serious sin. Someone who's castrated, obviously, won't be fornicating. * As an over-literal interpretation of Matthew 19:12, which says, \"There are also eunuchs who made themselves eunuchs for the sake of the kingdom of heaven.\" The verse isn't commanding this, but [in context](_URL_1_ 19 & version=NASB), someone could get the idea that it's recommended. The historian Eusebius says this's why Origen castrated himself. * As an influence from pagan cults, where some priests were castrated. I think this's why the Council condemned it." ]
[ "Paul. In the Gospels Jesus is fairly clear that the old law has been abolished (see Mathew 15:11 as the standard proof text for this)- that is that those Old Testament sins are no longer sins. But, the Gospels are not the end of the New Testament. In the Epistles the Bible condemns homosexuality (and other Old Testament sins). To the mind of many that makes it clear that while many of the Old Testament laws have been abolished not all of them have been.

According to Wikipedia, when the British left the falklands in 1774, they left a plaque claiming the islands for George III. What happened to this plaque? Is it still up?
[ "According to my copy of Martin Middlebrook's *The Falklands War* : > The plaque was later removed by a Spanish naval officer and taken to Buenos Aires. Since he says 'Spanish' and not 'Argentinian' I presumed the plaque was removed sometime before 1811 when the Spanish settlements in the Malvinas were withdrawn. Argentina became independent in 1816 and the next settlement was established by Argentinians in 1826, under British protest. So I did a little digging on Google books and in *The Falkland Islands*, Mary Cawkell says that the plaque was removed in 1775 by a party from Puerto Soledad. In turn Buenos Aires was captured by the British in June 1806^* and the plaque was taken and returned to London. After that I don't know. _URL_0_ ^* Buenos Aires was recaptured by Argentinian forces a month and a half later." ]
[ "The Falklands is a British colony, they don't have any voting rights, but are technically British citizens and the majority are of British ethnicity, and they would rather stay under British rule. Argentina believe the islands should be under Argentine rule because when they gained independence they also gained the Falklands and had settlers there before the British expelled them and colonised in the early 19th century. Also, the Falkland Islands are too small to survive as an independent state according to the UN." ]

Incest in Medieval European Villages
[ "So first, yes, many people didn't travel far, but a lot of recent work has shown that medieval horizons were much broader than people first thought. Pulling a wife from a neighboring village would not be like venturing off to find the grail. Second, villages weren't so very small, by and large - I don't know of an actual study of average size, but 50 wouldn't be too absurd. Third, and most important, the Church forbade marriage within seven degrees of consanguinity. While there were often dispensations given to nobility (see the aformentioned Hapsburgs), the process would be cost-prohibitive for almost everyone else. On the other hand, few people - even noble families - could trace their lineages back that far, so the extreme limits of the rule were probably not well enforced." ]

[ "I don't recall any of the South American dictatorships of the 70s ending by war or external pressure. The case which I'm most familiar with, Uruguay, had been in a dictatorship since 1973, and in 1980 the military junta in power tried to give some legitimacy to its government, proposing a new constitution which would effectively result in a very flawed democracy. That constitution was submitted to a popular vote, and rebuffed, even with all the weight of the state press behind it, and many politicians who were against it either in jail or in exile. Afterwards, the military junta recognized they had effectively lost popular support, and negotiated a elections in 1984 with a full return to democracy in 1985.

Russia has a huge territory just in front of Japan and not far from South Korea. Why is it that this region is not super developed/integrated with these economies?

Was it true that the Soviet Army didn't use any ranks at the beginning?
[ "The Red Army did get rid of 'ranks' in a more superficial sense in that someone commanding a division would be called a 'division commander', rather than 'general' (Or whichever rank commands a division, I'm not sure). There was a broad push to do away, even if just superficially, with symbols of the old order (not just in the military) - this is why there were commanders instead of officers and commissars instead of ministers, for example. So basically, no. They renamed (and often reorganised) the ranks and structures that existed. There were still definite chains of command once the Red Army was organised. I can't speak to the PLA or Albanian army, but I would imagine it would be a similar story. Someone with more of a background in the Soviets could give you some info on why they did this.

Cartoons and children's toys often portray circus trains as having a giraffe car where the giraffe's neck sticks out through the roof. Did circuses ever actually transport giraffes like that?
[ "Not in the way that the whimsical toys would lead you to believe. Starting around the turn of the century circuses around the US had special livestock cars built to handle exotic animals. The Ringling Brothers' current fleet are built from ex Union Pacific railway post office cars with special quarters for each animal type. Older cars used in the early 20th century were outside braced wooden livestock cars with side and end doors to unload animals. You couldn't have giraffe heads poking out of the top of the car for numerous reasons, not least because transporting them in that fashion would cause them to suffocate from exhaust in tunnels and get injured by debris or low clearance obstacles. They were most likely trained to lay down, which would provide at least 8-10 feet of ceiling height. You can learn more here: _URL_0_" ]
[ "I had to do a little research for this, but apparently it has always been a circus act. It originated from the \"Cole Bros. Circus\" in the 1950s. According to circus performers, the average car can fit between 14 and 20 clowns when all the interior is stripped out, there is no use of trapdoors or the like, and the cars are actually drivable." ]

Was there an idea of career mobility in the middle ages?
[ "Working in the Royal Household in England could be similar to what you are describing. While the loftiest positions (Treasurer, Steward, Captain of the Guard, etc.) were royal appointments, many of the people in lower positions (clerks, cooks, grooms, and other servants) worked their way up the ladder of promotions. Many people started as nonsalaried servants, paid in food and lodging, and were promoted based on their skills, aptitude and seniority. Eventually they could achieve quite lucrative positions like the head cook (who had rights to use/sell certain items that came through the kitchens, like lambskins). The highest position that one could be promoted into was the cashier/cofferer of the household - they were, effectively, responsible for the running of the royal household (especially in financial matters) and sat on the Board of the Greencloth - the board that determined all financial matters for the royal household - alongside nobles who were appointed to the board." ]

Salt as a factor in the Whisky Rebellion?
[ "Kurlansky is vastly overstating the importance of salt in the Whiskey Rebellion. Back-country farmers were using whiskey as a barter medium and a sale item. They may have traded whiskey for salt, but salt was not the only item--nor the most important one--for which farmers traded whiskey. And the revolt was absolultey not prompted by denying back-country farmers access to NaCl. To read more about the real reasons for the Whiskey Rebellion, I recommend Tom Slaughter's *The Whiskey Rebellion: Frontier Epilogue to the American Revolution* (Oxford University Press, 1986). I hope Kurlansky is worth his salt as a historian in other areas. His argument here is rather tasteless." ]

Snow shovels, snow blowers, window ice scrapers--when and how were they invented?
[ "There's a difference between commercial/industrial snow removal and consumer products. On the consumer front, the first snow blower designed for residential use that I am aware of was the Toro Snow Hound in 1951. Toro, a Minneapolis company founded to build tractor engines, had moved into mowers by the 1920s. After switching to armaments during WWII, they expanded their line rapidly in the 1950s as rising affluence and suburbanization drove demand for walk-behind mowers and ultimately snow blowers as well. The Snow Hound, Snow Boy, and Snow Pup were among the early consumer snow blowers of that era, and show up in magazine ads in snowbelt states quite frequently. Toro has a [brief company history](_URL_0_) on its website (.pfd) that offers a bit more detail.

How are historians able to piece together battle diagrams of ancient/historical battles?

One of my sources (Barrie Goedhals, \"John Barbour, 'The Bruce,' and Bannockburn,\" 1968) includes a map of the battle that he says is \"reconstructed from Barbour's account and those of other chroniclers.\" I assume that this is a fairly common method creating diagrams of any historical battle. There are often multiple accounts - at least one from each side - that talk about what happened, what the battlefield looked like from their perspective, who stood where, etc." ]
[ "Although obviously in a different style, most Roman primary sources that cover battles will give a play-by-play of the battle, although if you're not familiar with the style of writing can be hard to understand and probably the closest to an actual after-action style report would probably come from Caesar's conquest of Gaul as it is written by the man himself about, surprisingly, his conquest of Gaul and the battles that took place there." ]

Before the World War I, US was considered isolationist but the country entered the war enthusiastically. Why? Did propaganda play a big role in this?
[ "There was in fact a gradual shift in US public opinion away from isolationism prior to 1917. The central issue was Germany's unrestricted submarine warfare policy, which often indiscriminately destroyed both British and neutral shipping that resulted in the death of American citizens; demonstrated most prominently by the sinking of the _Lusitania_. While Germany - rightly - noted that this was simply in response to British blockade, Germany failed to realize that there was a gulf of difference between the German and British methods. For the Americans, their quarrel with the British blockade was merely a question of commerce. By contrast their quarrel with the Germans was a matter of life-and-death for American citizens traveling on ships plying the North Atlantic. What really tipped the scales moreover was the Zimmerman Telegram, wherein Germany promised to support Mexico if it went to war against the United States. This pretty much solidified support for the war." ]

Which civilization is technically the first to invent paper?
[ "The surfaces for writing on in the ancient Mediterranean and Near East were papyrus, clay (where papyrus was unavailable), wax on wood (for short-term notes), and parchment. Paper didn't arrive in the Mediterranean until the 8th century CE, at which point the idea was imported from China. European paper at that time was made of linen or hemp rather than wood. Put another way, paper was invented once (in Han China) and from that one-time invention it eventually spread over the world. I don't have access to Bauer's book, but it would be easier to assess the exact nature of the claim if you could tell us her exact wording and context when she makes this implication, and/or what evidence she cites.
