Although the strength of individual CNT shells is extremely high, weak shear interactions between adjacent shells and tubes lead to significant reduction in the effective strength of multiwalled carbon nanotubes and carbon nanotube bundles down to only a few GPa. This limitation has been recently addressed by applying high-energy electron irradiation, which crosslinks inner shells and tubes, and effectively increases the strength of these materials to ≈60 GPa for multiwalled carbon nanotubes and ≈17 GPa for double-walled carbon nanotube bundles. CNTs are not nearly as strong under compression. Because of their hollow structure and high aspect ratio, they tend to undergo buckling when placed under compressive, torsional, or bending stress.
On the other hand, there is evidence that in the radial direction they are rather soft. The first transmission electron microscope observation of radial elasticity suggested that even van der Waals forces can deform two adjacent nanotubes. Later, nanoindentations with an atomic force microscope were performed by several groups to quantitatively measure the radial elasticity of multiwalled carbon nanotubes and tapping/contact mode atomic force microscopy was also performed on single-walled carbon nanotubes. Their high Young's modulus in the linear direction, of on the order of several GPa (and even up to an experimentally-measured 1.8 TPa, for nanotubes near 2.4 μm in length), further suggests they may be soft in the radial direction.

Electrical.
Unlike graphene, which is a two-dimensional semimetal, carbon nanotubes are either metallic or semiconducting along the tubular axis. For a given ("n","m") nanotube, if "n" = "m", the nanotube is metallic; if "n" − "m" is a multiple of 3 and n ≠ m, then the nanotube is quasi-metallic with a very small band gap, otherwise the nanotube is a moderate semiconductor.
Thus, all armchair ("n" = "m") nanotubes are metallic, and nanotubes (6,4), (9,1), etc. are semiconducting.
Carbon nanotubes are not semimetallic because the degenerate point (the point where the π [bonding] band meets the π* [anti-bonding] band, at which the energy goes to zero) is slightly shifted away from the "K" point in the Brillouin zone because of the curvature of the tube surface, causing hybridization between the σ* and π* anti-bonding bands, modifying the band dispersion.
|
Because of its nanoscale cross-section, electrons propagate only along the tube's axis. As a result, carbon nanotubes are frequently referred to as one-dimensional conductors. The maximum electrical conductance of a single-walled carbon nanotube is 2"G"0, where "G"0 = 2"e"2/"h" is the conductance of a single ballistic quantum channel.
Because of the role of the π-electron system in determining the electronic properties of graphene, doping in carbon nanotubes differs from that of bulk crystalline semiconductors from the same group of the periodic table (e.g., silicon). Graphitic substitution of carbon atoms in the nanotube wall by boron or nitrogen dopants leads to p-type and n-type behavior, respectively, as would be expected in silicon. However, some non-substitutional (intercalated or adsorbed) dopants introduced into a carbon nanotube, such as alkali metals and electron-rich metallocenes, result in n-type conduction because they donate electrons to the π-electron system of the nanotube. By contrast, π-electron acceptors such as FeCl3 or electron-deficient metallocenes function as p-type dopants because they draw π-electrons away from the top of the valence band.

Intrinsic superconductivity has been reported, although other experiments found no evidence of this, leaving the claim a subject of debate.
In 2021, Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT, published department findings on the use of carbon nanotubes to create an electric current. By immersing the structures in an organic solvent, the liquid drew electrons out of the carbon particles. Strano was quoted as saying, "This allows you to do electrochemistry, but with no wires," and represents a significant breakthrough in the technology. Future applications include powering micro- or nanoscale robots, as well as driving alcohol oxidation reactions, which are important in the chemicals industry.
Crystallographic defects also affect the tube's electrical properties. A common result is lowered conductivity through the defective region of the tube. A defect in metallic armchair-type tubes (which can conduct electricity) can cause the surrounding region to become semiconducting, and single monatomic vacancies induce magnetic properties.
|
Electromechanical.
Semiconducting carbon nanotubes have shown piezoresistive property when applying mechanical force. The structural deformation causes a change in the band gap which effects the conductance. This property has the potential to be used in strain sensors.
Optical.
Carbon nanotubes have useful absorption, photoluminescence (fluorescence), and Raman spectroscopy properties. Spectroscopic methods offer the possibility of quick and non-destructive characterization of relatively large amounts of carbon nanotubes. There is a strong demand for such characterization from the industrial point of view: numerous parameters of nanotube synthesis can be changed, intentionally or unintentionally, to alter the nanotube quality, such as the non-tubular carbon content, structure (chirality) of the produced nanotubes, and structural defects. These features then determine nearly all other significant optical, mechanical, and electrical properties.
Carbon nanotube optical properties have been explored for use in applications such as for light-emitting diodes (LEDs) and photo-detectors based on a single nanotube have been produced in the lab. Their unique feature is not the efficiency, which is yet relatively low, but the narrow selectivity in the wavelength of emission and detection of light and the possibility of its fine-tuning through the nanotube structure. In addition, bolometer and optoelectronic memory devices have been realised on ensembles of single-walled carbon nanotubes. Nanotube fluorescence has been investigated for the purposes of imaging and sensing in biomedical applications.
|
Thermal.
All nanotubes are expected to be very good thermal conductors along the tube, exhibiting a property known as "ballistic conduction", but good insulators lateral to the tube axis. Measurements show that an individual SWNT has a room-temperature thermal conductivity along its axis of about 3500 W·m−1·K−1; compare this to copper, a metal well known for its good thermal conductivity, which transmits 385 W·m−1·K−1. An individual SWNT has a room-temperature thermal conductivity lateral to its axis (in the radial direction) of about 1.52 W·m−1·K−1, which is about as thermally conductive as soil. Macroscopic assemblies of nanotubes such as films or fibres have reached up to 1500 W·m−1·K−1 so far. Networks composed of nanotubes demonstrate different values of thermal conductivity, from the level of thermal insulation with the thermal conductivity of 0.1 W·m−1·K−1 to such high values. That is dependent on the amount of contribution to the thermal resistance of the system caused by the presence of impurities, misalignments and other factors. The temperature stability of carbon nanotubes is estimated to be up to 2800 °C in vacuum and about 750 °C in air.
|
Crystallographic defects strongly affect the tube's thermal properties. Such defects lead to phonon scattering, which in turn increases the relaxation rate of the phonons. This reduces the mean free path and reduces the thermal conductivity of nanotube structures. Phonon transport simulations indicate that substitutional defects such as nitrogen or boron will primarily lead to the scattering of high-frequency optical phonons. However, larger-scale defects such as Stone–Wales defects cause phonon scattering over a wide range of frequencies, leading to a greater reduction in thermal conductivity.
Antibacterial.
Recently, carbon-nanotubes have been shown to have antibacterial properties. They disrupt normal bacterial function by causing physical/mechanical damage, facilitating oxidative stress or lipid extraction, inhibiting bacterial metabolism, and isolating functional sites via wrapping with CNM-containing nanomaterials.
Synthesis.
|
Vertically aligned carbon nanotube arrays are also grown by thermal chemical vapor deposition. A substrate (quartz, silicon, stainless steel, carbon fibers, etc.) is coated with a catalytic metal (Fe, Co, Ni) layer. Typically that layer is iron and is deposited via sputtering to a thickness of 1–5 nm. A 10–50 nm underlayer of alumina is often also put down on the substrate first. This imparts controllable wetting and good interfacial properties.
When the substrate is heated to the growth temperature (~600 to 850 °C), the continuous iron film breaks up into small islands with each island then nucleating a carbon nanotube. The sputtered thickness controls the island size and this in turn determines the nanotube diameter. Thinner iron layers drive down the diameter of the islands and drive down the diameter of the nanotubes grown. The amount of time the metal island can sit at the growth temperature is limited as they are mobile and can merge into larger (but fewer) islands. Annealing at the growth temperature reduces the site density (number of CNT/mm2) while increasing the catalyst diameter.
|
The as-prepared carbon nanotubes always have impurities such as other forms of carbon (amorphous carbon, fullerene, etc.) and non-carbonaceous impurities (metal used for catalyst). These impurities need to be removed to make use of the carbon nanotubes in applications.
Purification.
As-synthesized carbon nanotubes typically contain impurities and most importantly different chiralities of carbon nanotubes. Therefore, multiple methods have been developed to purify them including polymer-assisted, density gradient ultracentrifugation (DGU), chromatography and aqueous two-phase extraction (ATPE). These methods have been reviewed in multiple articles.
Certain polymers selectively disperse or wrap CNTs of a particular chirality, metallic character or diameter. For example, poly(phenylenevinylenes) disperses CNTs of specific diameters (0.75–0.84 nm) and polyfluorenes are highly selective for semiconducting CNTs. It involves mainly two steps, sonicate the mixture (CNTs and polymers in solvent), centrifuge and the supernatant are desired CNTs.
|
Density gradient ultracentrifugation is a method based on the density difference of CNTs, so that different components are layered in centrifuge tubes under centrifugal force. Chromatography-based methods include size exclusion (SEC), ion-exchange (IEX) and gel chromatography. For SEC, CNTs are separated due to the difference in size using a stationary phase with different pore size. As for IEX, the separation is achieved based on their differential adsorption and desorption onto chemically functionalized resins packed in an IEX column, so understanding the interaction between CNTs mixtures and resins is important. The first IEX is reported to separate DNA-SWCNTs. Gel chromatography is based on the partition of CNTs between stationary and mobile phase, it's found semiconducting CNTs are more strongly attracted by gel than metallic CNTs. While it shows potential, the current application is limited to the separation of semiconducting (n,m) species.
ATPE uses two water-soluble polymers such as polyethylene glycol (PEG) and dextran. When mixed, two immiscible aqueous phases form spontaneously, and each of the two phases shows a different affinity to CNTs. Partition depends on the solvation energy difference between two similar phases of microscale volumes. By changing the separation system or temperatures, and adding strong oxidants, reductants, or salts, the partition of CNTs species into the two phases can be adjusted.
|
Despite the progress that has been made to separate and purify CNTs, many challenges remain, such as the growth of chirality-controlled CNTs, so that no further purification is needed, or large-scale purification.
Advantages of monochiral CNTs.
Monochiral CNTs have the advantage that they do contain less or no impurities, well-defined non-congested optical spectra. This allows to create for example CNT-based biosensors with higher sensitivity and selectivity. For example, monochiral SWCNTs are necessary for multiplexed and ratiometric sensing schemes, enhanced sensitivity of biocompatibility.
Functionalization.
Carbon nanotubes can be functionalized to attain desired properties that can be used in a wide variety of applications. The two main methods of carbon nanotube functionalization are covalent and non-covalent modifications. Because of their apparent hydrophobic nature, carbon nanotubes tend to agglomerate hindering their dispersion in solvents or viscous polymer melts. The resulting nanotube bundles or aggregates reduce the mechanical performance of the final composite. The surface of the carbon nanotubes can be modified to reduce the hydrophobicity and improve interfacial adhesion to a bulk polymer through chemical attachment.
|
Chemical routes such as covalent functionalization have been studied extensively, which involves the oxidation of CNTs via strong acids (e.g. sulfuric acid, nitric acid, or a mixture of both) in order to set the carboxylic groups onto the surface of the CNTs as the final product or for further modification by esterification or amination. Free radical grafting is a promising technique among covalent functionalization methods, in which alkyl or aryl peroxides, substituted anilines, and diazonium salts are used as the starting agents.
Functionalization can improve CNTs characteristically weak dispersibility in many solvents, such as water - a consequence of their strong intermolecular p–p interactions. This can enhance the processing and manipulation of insoluble CNTs, rendering them useful for synthesizing innovative CNT nanofluids with impressive properties that are tunable for a wide range of applications.
Free radical grafting of macromolecules (as the functional group) onto the surface of CNTs can improve the solubility of CNTs compared to common acid treatments which involve the attachment of small molecules such as hydroxyl onto the surface of CNTs. The solubility of CNTs can be improved significantly by free-radical grafting because the large functional molecules facilitate the dispersion of CNTs in a variety of solvents even at a low degree of functionalization. Recently an innovative environmentally friendly approach has been developed for the covalent functionalization of multi-walled carbon nanotubes (MWCNTs) using clove buds. This approach is innovative and green because it does not use toxic and hazardous acids which are typically used in common carbon nanomaterial functionalization procedures. The MWCNTs are functionalized in one pot using a free radical grafting reaction. The clove-functionalized MWCNTs are then dispersed in water producing a highly stable multi-walled carbon nanotube aqueous suspension (nanofluids).
|
The surface of carbon nanotubes can be chemically modified by coating spinel nanoparticles by hydrothermal synthesis and can be used for water oxidation purposes.
In addition, the surface of carbon nanotubes can be fluorinated or halofluorinated by heating while in contact with a fluoroorganic substance, thereby forming partially fluorinated carbons (so-called Fluocar materials) with grafted (halo)fluoroalkyl functionality.
Modeling.
Carbon nanotubes are modelled in a similar manner as traditional composites in which a reinforcement phase is surrounded by a matrix phase. Ideal models such as cylindrical, hexagonal and square models are common. The size of the micromechanics model is highly function of the studied mechanical properties. The concept of representative volume element (RVE) is used to determine the appropriate size and configuration of the computer model to replicate the actual behavior of the CNT-reinforced nanocomposite. Depending on the material property of interest (thermal, electrical, modulus, creep), one RVE might predict the property better than the alternatives. While the implementation of the ideal model is computationally efficient, they do not represent microstructural features observed in scanning electron microscopy of actual nanocomposites. To incorporate realistic modeling, computer models are also generated to incorporate variability such as waviness, orientation and agglomeration of multiwall or single-wall carbon nanotubes.
|
Metrology.
There are many metrology standards and reference materials available for carbon nanotubes.
For single-wall carbon nanotubes, ISO/TS 10868 describes a measurement method for the diameter, purity, and fraction of metallic nanotubes through optical absorption spectroscopy, while ISO/TS 10797 and ISO/TS 10798 establish methods to characterize the morphology and elemental composition of single-wall carbon nanotubes, using transmission electron microscopy and scanning electron microscopy respectively, coupled with energy dispersive X-ray spectrometry analysis.
NIST SRM 2483 is a soot of single-wall carbon nanotubes used as a reference material for elemental analysis, and was characterized using thermogravimetric analysis, prompt gamma activation analysis, induced neutron activation analysis, inductively coupled plasma mass spectroscopy, resonant Raman scattering, UV-visible-near infrared fluorescence spectroscopy and absorption spectroscopy, scanning electron microscopy, and transmission electron microscopy. The Canadian National Research Council also offers a certified reference material SWCNT-1 for elemental analysis using neutron activation analysis and inductively coupled plasma mass spectroscopy. NIST RM 8281 is a mixture of three lengths of single-wall carbon nanotube.
|
For multiwall carbon nanotubes, ISO/TR 10929 identifies the basic properties and the content of impurities, while ISO/TS 11888 describes morphology using scanning electron microscopy, transmission electron microscopy, viscometry, and light scattering analysis. ISO/TS 10798 is also valid for multiwall carbon nanotubes.
Safety and health.
The National Institute for Occupational Safety and Health (NIOSH) is the leading United States federal agency conducting research and providing guidance on the occupational safety and health implications and applications of nanomaterials. Early scientific studies have indicated that nanoscale particles may pose a greater health risk than bulk materials due to a relative increase in surface area per unit mass. Increase in length and diameter of CNT is correlated to increased toxicity and pathological alterations in the lungs. The biological interactions of nanotubes are not well understood, and the field is open to continued toxicological studies. It is often difficult to separate confounding factors, and since carbon is relatively biologically inert, some of the toxicity attributed to carbon nanotubes may be instead due to residual metal catalyst contamination. |
It is often difficult to separate confounding factors, and since carbon is relatively biologically inert, some of the toxicity attributed to carbon nanotubes may be instead due to residual metal catalyst contamination. In previous studies, only Mitsui-7 was reliably demonstrated to be carcinogenic, although for unclear/unknown reasons. Unlike many common mineral fibers (such as asbestos), most SWCNTs and MWCNTs do not fit the size and aspect-ratio criteria to be classified as respirable fibers. In 2013, given that the long-term health effects have not yet been measured, NIOSH published a Current Intelligence Bulletin detailing the potential hazards and recommended exposure limit for carbon nanotubes and fibers. The U.S. National Institute for Occupational Safety and Health has determined non-regulatory recommended exposure limits (RELs) of 1 μg/m3 for carbon nanotubes and carbon nanofibers as background-corrected elemental carbon as an 8-hour time-weighted average (TWA) respirable mass concentration. |
As of October 2016, single-wall carbon nanotubes have been registered through the European Union's Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulations, based on evaluation of the potentially hazardous properties of SWCNT. Based on this registration, SWCNT commercialization is allowed in the EU up to 100 metric tons. Currently, the type of SWCNT registered through REACH is limited to the specific type of single-wall carbon nanotubes manufactured by OCSiAl, which submitted the application.
Applications.
Carbon nanotubes are currently used in multiple industrial and consumer applications. These include battery components, polymer composites, to improve the mechanical, thermal and electrical properties of the bulk product, and as a highly absorptive black paint. Many other applications are under development, including field effect transistors for electronics, high-strength fabrics, biosensors for biomedical and agricultural applications, and many others.
Biomedical Applications.
|
Because of their relatively large surface area, CNTs are capable of interacting with a wide variety of therapeutic and diagnostic agents (drugs, genes, vaccines, antibodies, biosensors, etc.). This can be utilized to assist in drug delivery directly into cells. In addition, CNTs have recently been used as reinforcements in implants and scaffolds due to their suitable reaction area, high elastic modulus, and load transfer capability.
CNTs have been shown to increase the effectiveness of bioactive coatings for the attachment, proliferation, and differentiation of osteoblasts, and has been used as a bone substitution material.
CNTs may be used as reinforcing materials for chitosan-containing coatings used on implants and medical scaffolds.
Biosensing.
SWCNTs have nanoscale dimensions that fit to the size of biological species. Due to this size compatibility and their large surface-to-volume ratio, they are sensitive to changes in their chemical environment. Through covalent and non-covalent surface functionalization, SWCNTs can be precisely tailored for selective molecular interactions with a target analyte. The SWCNT represents the transduction unit that converts the interaction into a signal change (optical or electrical). Due to continuous progress in the development of detection strategies, there are numerous examples of the use of SWCNTs as highly sensitive nanosensors (even down to the single molecule level) for a variety of important biomolecules. Examples include the detection of reactive oxygen and nitrogen species, neurotransmitters, other small molecules, lipids, proteins, sugars, DNA/RNA, enzymes as well as bacteria.
|
The signal change manifests itself in an increase or decrease in the current (electrical) or in a change in the intensity or wavelength of the fluorescence emission (optical). Depending on the type of application, both electrical or optical signal transmission can be advantageous. For sensitive measurement of electronic changes, field-effect transistors (FET) are often used in which the flow of charges within the SWCNTs is measured. The FET structures allow easy on-chip integration and can be parallelized to detect multiple target analytes simultaneously. However, such sensors are more invasive for in vivo applications, as the entire device has to be inserted into the body. Optical detection with semiconducting SWCNTs is based on the radiative recombination of excitons in the near-infrared (NIR) by prior optical (fluorescence) or electrical excitation (electroluminescence). The emission in the NIR enables detection in the biological transparency window, where optical sensor applications benefit from reduced scattering and autofluorescence of biological samples and consequently a high signal-to-noise ratio. |
where optical sensor applications benefit from reduced scattering and autofluorescence of biological samples and consequently a high signal-to-noise ratio. Compared to optical sensors in the UV or visible range, the penetration depth in biological tissue is also increased. In addition to the advantage of a contactless readout SWCNTs have excellent photostability, which enables long-term sensor applications. Furthermore, the nanoscale size of SWCNTs allows dense coating of surfaces which enables chemical imaging, e.g. of cellular release processes with high spatial and temporal resolution. Detection of several target analytes is possible by the spatial arrangement of different SWCNT sensors in arrays or by hyperspectral detection based on monochiral SWCNT sensors that emit at different emission wavelengths. For fluorescence applications, however, optical filters to distinguish between excitation and emission and a NIR-sensitive detector must be used. Standard silicon detectors can also be used if monochiral SWCNTs (extractable by special purification processes) emitting closer to the visible range (800 – 900 nm) are used. |
Standard silicon detectors can also be used if monochiral SWCNTs (extractable by special purification processes) emitting closer to the visible range (800 – 900 nm) are used. In order to avoid susceptibility of optical sensors to fluctuating ambient light, internal references such as SWCNTs that are modified to be non-responsive or stable NIR emitters can be used. An alternative is to measure fluorescence lifetimes instead of fluorescence intensities. Overall, SWCNTs therefore have great potential as building blocks for various biosensors.
To render SWCNTs suitable for biosensing, their surface needs to be modified to ensure colloidal stability and provide a handle for biological recognition. Therefore, biosensing and surface modifications (functionalization) are closely related.
Potential future applications include biomedical and environmental applications such as monitoring plant health in agriculture, standoff process control in bioreactors, research/diagnostics of neuronal communication and numerous diseases such as coagulation disorders, diabetes, cancer, microbial and viral infections, testing the efficacy of pharmaceuticals or infection monitoring using smart implants. In industry, SWCNTs are already used as sensors in the detection of gases and odors in the form of an electronic nose or in enzyme screening.

Applications under development.
Applications of nanotubes in development in academia and industry include:
Carbon nanotubes can serve as additives to various structural materials. For instance, nanotubes form a tiny portion of the material(s) in some (primarily carbon fiber) baseball bats, golf clubs, car parts, or damascus steel.
IBM expected carbon nanotube transistors to be used on Integrated Circuits by 2020.
SWCNTs have found use in long lasting, faster charged lithium ion batteries; polyamide car parts for e-painting; automotive primers for cost benefits and better aesthetics of topcoats; ESD floors; electrically conductive lining coatings for tanks and pipes; rubber parts with improved heat and oil aging stability; conductive gelcoats for ATEX requirements and tooling conductive gelcoats for increased safety and efficiency; and heating fiber coatings for infrastructure elements.
Potential/Future applications.
|
CNTs are potential candidates for future via and wire material in nano-scale VLSI circuits. Eliminating electromigration reliability concerns that plague today's Cu interconnects, isolated (single and multi-wall) CNTs can carry current densities in excess of 1000 MA/cm2 without electromigration damage.
Single-walled nanotubes are likely candidates for miniaturizing electronics. The most basic building block of these systems is an electric wire, and SWNTs with diameters of an order of a nanometre can be excellent conductors. One useful application of SWNTs is in the development of the first intermolecular field-effect transistors (FET). The first intermolecular logic gate using SWCNT FETs was made in 2001. A logic gate requires both a p-FET and an n-FET. Because SWNTs are p-FETs when exposed to oxygen and n-FETs otherwise, it is possible to expose half of an SWNT to oxygen and protect the other half from it. The resulting SWNT acts as a "not" logic gate with both p- and n-type FETs in the same molecule.
Large quantities of pure CNTs can be made into a freestanding sheet or film by surface-engineered tape-casting (SETC) fabrication technique which is a scalable method to fabricate flexible and foldable sheets with superior properties. Another reported form factor is CNT fiber (a.k.a. filament) by wet spinning. The fiber is either directly spun from the synthesis pot or spun from pre-made dissolved CNTs. Individual fibers can be turned into a yarn. Apart from its strength and flexibility, the main advantage is making an electrically conducting yarn. The electronic properties of individual CNT fibers (i.e. bundle of individual CNT) are governed by the two-dimensional structure of CNTs. The fibers were measured to have a resistivity only one order of magnitude higher than metallic conductors at . By further optimizing the CNTs and CNT fibers, CNT fibers with improved electrical properties could be developed.
CNT-based yarns are suitable for applications in energy and electrochemical water treatment when coated with an ion-exchange membrane. Also, CNT-based yarns could replace copper as a winding material. Pyrhönen et al. (2015) have built a motor using CNT winding.

Czech Republic
The Czech Republic, also known as Czechia, and historically known as Bohemia, is a landlocked country in Central Europe. The country is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec.
The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial Estate of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, all of the Lands of the Bohemian Crown were gradually integrated into the Habsburg monarchy. Nearly a hundred years later, the Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Roman Empire in 1806, the Crown lands became part of the Austrian Empire.
|
In the 19th century, the Czech lands became more industrialized; further, in 1918, most of the country became part of the First Czechoslovak Republic following the collapse of Austria-Hungary after World War I. Czechoslovakia was the only country in Central and Eastern Europe to remain a parliamentary democracy during the entirety of the interwar period. After the Munich Agreement in 1938, Nazi Germany systematically took control over the Czech lands. Czechoslovakia was restored in 1945 and three years later became an Eastern Bloc communist state following a coup d'état in 1948. Attempts to liberalize the government and economy were suppressed by a Soviet-led invasion of the country during the Prague Spring in 1968. In November 1989, the Velvet Revolution ended communist rule in the country and restored democracy. On 31 December 1992, Czechoslovakia was peacefully dissolved, with its constituent states becoming the independent states of the Czech Republic and Slovakia.
The Czech Republic is a unitary parliamentary republic and developed country with an advanced, high-income social market economy. It is a welfare state with a European social model, universal health care and free-tuition university education. It ranks 32nd in the Human Development Index. The Czech Republic is a member of the United Nations, NATO, the European Union, the OECD, the OSCE, the Council of Europe and the Visegrád Group.

Etymology.
The traditional English name "Bohemia" derives from Latin "Boiohaemum", which means "home of the Boii" (a Gallic tribe). The current English name ultimately comes from the Czech word . The name comes from the Slavic tribe () and, according to legend, their leader Čech, who brought them to Bohemia, to settle on Říp Mountain. The etymology of the word is uncertain, but according to the most common derivation can be traced back to the Proto-Slavic root , meaning "member of the people; kinsman", thus making it cognate to the Czech word (a person).
The country has been traditionally divided into three lands, namely Bohemia () in the west, Moravia () in the east, and Czech Silesia (; the smaller, south-eastern part of historical Silesia, most of which is located within modern Poland) in the northeast. Known as the "lands of the Bohemian Crown" since the 14th century, a number of other names for the country have been used, including "Czech/Bohemian lands", "Bohemian Crown", "Czechia", and the "lands of the Crown of Saint Wenceslaus". When the country regained its independence after the dissolution of the Austro-Hungarian empire in 1918, the new name of "Czechoslovakia" was coined to reflect the union of the Czech and Slovak nations within one country.
|
After Czechoslovakia dissolved on the last day of 1992, was adopted as the Czech short name for the new state and the Ministry of Foreign Affairs of the Czech Republic recommended "Czechia" for the English-language equivalent. This form was not widely adopted at the time, leading to the long name "Czech Republic" being used in English in nearly all circumstances. The Czech government directed use of "Czechia" as the official English short name in 2016. The short name has been listed by the United Nations and is used by other organizations such as the European Union, NATO, the CIA, Google Maps, and the European Broadcasting Union. In 2022, the American "AP Stylebook" stated in its entry on the country that "both [Czechia and the Czech Republic] are acceptable. The shorter name Czechia is preferred by the Czech government. If using Czechia, clarify in the story that the country is more widely known in English as the Czech Republic."
History.
Prehistory.
Archaeological evidence indicates that the area now known as the Czech Republic has been inhabited since the Paleolithic era. Notably, the Venus of Dolní Věstonice, a ceramic figurine dated to approximately 29,000–25,000 BCE, was discovered in this region. This artifact is considered the oldest known ceramic figurine in the world.
|
In the classical era, as a result of the 3rd century BC Celtic migrations, Bohemia became associated with the Boii. The Boii founded an oppidum near the site of modern Prague. Later in the 1st century, the Germanic tribes of the Marcomanni and Quadi settled there.
Slavs from the Black Sea–Carpathian region settled in the area (their migration was pushed by an invasion of peoples from Siberia and Eastern Europe into their area: Huns, Avars, Bulgars and Magyars). In the sixth century, the Huns had moved westwards into Bohemia, Moravia, and some of present-day Austria and Germany.
During the 7th century, the Frankish merchant Samo, supporting the Slavs fighting against nearby settled Avars, became the ruler of the first documented Slavic state in Central Europe, Samo's Empire. The principality of Great Moravia, controlled by Moymir dynasty, arose in the 8th century. It reached its zenith in the 9th (during the reign of Svatopluk I of Moravia), holding off the influence of the Franks. Great Moravia was Christianized, with a role being played by the Byzantine mission of Cyril and Methodius. They codified the Old Church Slavonic language, the first literary and liturgical language of the Slavs, and the Glagolitic script.

Bohemia.
The Duchy of Bohemia emerged in the late 9th century when it was unified by the Přemyslid dynasty. Bohemia was from 1002 until 1806 an Imperial Estate of the Holy Roman Empire.
In 1212, Přemysl Ottokar I extracted the Golden Bull of Sicily from the emperor, confirming Ottokar and his descendants' royal status; the Duchy of Bohemia was raised to a Kingdom. German immigrants settled in the Bohemian periphery in the 13th century. The Mongols in the invasion of Europe carried their raids into Moravia but were defensively defeated at Olomouc.
After a series of dynastic wars, the House of Luxembourg gained the Bohemian throne.
Efforts for a reform of the church in Bohemia started already in the late 14th century. Jan Hus' followers seceded from some practices of the Roman Church and in the Hussite Wars (1419–1434) defeated five crusades organized against them by Sigismund. During the next two centuries, 90% of the population in Bohemia and Moravia were considered Hussites. The pacifist thinker Petr Chelčický inspired the movement of the Moravian Brethren (by the middle of the 15th century) that completely separated from the Roman Catholic Church.
|
On 21 December 1421, Jan Žižka, a successful military commander and mercenary, led his group of forces in the Battle of Kutná Hora, resulting in a victory for the Hussites. He is honoured to this day as a national hero.
After 1526, Bohemia came increasingly under Habsburg control as the Habsburgs became first the elected and then in 1627 the hereditary rulers of Bohemia. Between 1583 and 1611 Prague was the official seat of the Holy Roman Emperor Rudolf II and his court.
The Defenestration of Prague and subsequent revolt against the Habsburgs in 1618 marked the start of the Thirty Years' War. In 1620, the rebellion in Bohemia was crushed at the Battle of White Mountain and the ties between Bohemia and the Habsburgs' hereditary lands in Austria were strengthened. The leaders of the Bohemian Revolt were executed in 1621. The nobility and the middle class Protestants had to either convert to Catholicism or leave the country.
The following era of 1620 to the late 18th century became known as the "Dark Age". During the Thirty Years' War, the population of the Czech lands declined by a third through the expulsion of Czech Protestants as well as due to the war, disease and famine. The Habsburgs prohibited all Christian confessions other than Catholicism. The flowering of Baroque culture shows the ambiguity of this historical period.

Ottoman Turks and Tatars invaded Moravia in 1663. In 1679–1680 the Czech lands faced the Great Plague of Vienna and an uprising of serfs.
There were peasant uprisings influenced by famine. Serfdom was abolished between 1781 and 1848. Several battles of the Napoleonic Wars took place on the current territory of the Czech Republic.
The end of the Holy Roman Empire in 1806 led to degradation of the political status of Bohemia which lost its position of an electorate of the Holy Roman Empire as well as its own political representation in the Imperial Diet. Bohemian lands became part of the Austrian Empire. During the 18th and 19th century the Czech National Revival began its rise, with the purpose to revive Czech language, culture, and national identity. The Revolution of 1848 in Prague, striving for liberal reforms and autonomy of the Bohemian Crown within the Austrian Empire, was suppressed.
It seemed that some concessions would be made also to Bohemia, but in the end, the Emperor Franz Joseph I affected a compromise with Hungary only. The Austro-Hungarian Compromise of 1867 and the never realized coronation of Franz Joseph as King of Bohemia led to a disappointment of some Czech politicians. The Bohemian Crown lands became part of the so-called Cisleithania.

The Czech Social Democratic and progressive politicians started the fight for universal suffrage. The first elections under universal male suffrage were held in 1907.
Czechoslovakia.
In 1918, during the collapse of the Habsburg monarchy at the end of World War I, the independent republic of Czechoslovakia, which joined the winning Allied powers, was created, with Tomáš Garrigue Masaryk in the lead. This new country incorporated the Bohemian Crown.
The First Czechoslovak Republic comprised only 27% of the population of the former Austria-Hungary, but nearly 80% of the industry, which enabled it to compete with Western industrial states. In 1929 compared to 1913, the gross domestic product increased by 52% and industrial production by 41%. In 1938 Czechoslovakia held 10th place in the world industrial production. Czechoslovakia was the only country in Central and Eastern Europe to remain a liberal democracy throughout the entire
interwar period. Although the First Czechoslovak Republic was a unitary state, it provided certain rights to its minorities, the largest being Germans (23.6% in 1921), Hungarians (5.6%) and Ukrainians (3.5%).

Western Czechoslovakia was occupied by Nazi Germany, which placed most of the region into the Protectorate of Bohemia and Moravia. The Protectorate was proclaimed part of the Third Reich, and the president and prime minister were subordinated to Nazi Germany's "Reichsprotektor". One Nazi concentration camp was located within the Czech territory at Terezín, north of Prague. The vast majority of the Protectorate's Jews were murdered in Nazi-run concentration camps. The Nazi called for the extermination, expulsion, Germanization or enslavement of most or all Czechs for the purpose of providing more living space for the German people. There was Czechoslovak resistance to Nazi occupation as well as reprisals against the Czechoslovaks for their anti-Nazi resistance. The German occupation ended on 9 May 1945, with the arrival of the Soviet and American armies and the Prague uprising. Most of Czechoslovakia's German-speakers were forcibly expelled from the country, first as a result of local acts of violence and then under the aegis of an "organized transfer" confirmed by the Soviet Union, the United States, and Great Britain at the Potsdam Conference.

In the 1946 elections, the Communist Party gained 38% of the votes and became the largest party in the Czechoslovak parliament, formed a coalition with other parties, and consolidated power. A coup d'état came in 1948 and a single-party government was formed. For the next 41 years, the Czechoslovak Communist state conformed to Eastern Bloc economic and political features. The Prague Spring political liberalization was stopped by the 1968 Warsaw Pact invasion of Czechoslovakia. Analysts believe that the invasion caused the communist movement to fracture, ultimately leading to the Revolutions of 1989.
Czech Republic.
In November 1989, Czechoslovakia again became a liberal democracy through the Velvet Revolution. However, Slovak national aspirations strengthened (Hyphen War) and on 31 December 1992, the country peacefully split into the independent countries of the Czech Republic and Slovakia. Both countries went through economic reforms and privatizations, with the intention of creating a market economy, as they have been trying to do since 1990, when Czechs and Slovaks still shared the common state. This process was largely successful; in 2006 the Czech Republic was recognized by the World Bank as a "developed country", and in 2009 the Human Development Index ranked it as a nation of "Very High Human Development".
|
From 1991, the Czech Republic, originally as part of Czechoslovakia and since 1993 in its own right, has been a member of the Visegrád Group and from 1995, the OECD. The Czech Republic joined NATO on 12 March 1999 and the European Union on 1 May 2004. On 21 December 2007 the Czech Republic joined the Schengen Area.
Until 2017, either the centre-left Czech Social Democratic Party or the centre-right Civic Democratic Party led the governments of the Czech Republic. In October 2017, the populist movement ANO 2011, led by the country's second-richest man, Andrej Babiš, won the elections with three times more votes than its closest rival, the Civic Democrats. In December 2017, Czech president Miloš Zeman appointed Andrej Babiš as the new prime minister.
In the 2021 elections, ANO 2011 was narrowly defeated and Petr Fiala became the new prime minister. He formed a government coalition of the alliance SPOLU (Civic Democratic Party, KDU-ČSL and TOP 09) and the alliance of Pirates and Mayors. In January 2023, retired general Petr Pavel won the presidential election, becoming new Czech president to succeed Miloš Zeman. Following the 2022 Russian invasion of Ukraine, the country took in half a million Ukrainian refugees, the largest number per capita in the world.

Geography.
The Czech Republic lies mostly between latitudes 48° and 51° N and longitudes 12° and 19° E.
Bohemia, to the west, consists of a basin drained by the Elbe () and the Vltava rivers, surrounded by mostly low mountains, such as the Krkonoše range of the Sudetes. The highest point in the country, Sněžka at , is located here. Moravia, the eastern part of the country, is also hilly. It is drained mainly by the Morava River, but it also contains the source of the Oder River ().
Water from the Czech Republic flows to three different seas: the North Sea, Baltic Sea, and Black Sea. The Czech Republic also leases the Moldauhafen, a lot in the middle of the Hamburg Docks, which was awarded to Czechoslovakia by Article 363 of the Treaty of Versailles, to allow the landlocked country a place where goods transported down river could be transferred to seagoing ships. The territory reverts to Germany in 2028.
Phytogeographically, the Czech Republic belongs to the Central European province of the Circumboreal Region, within the Boreal Kingdom. According to the World Wide Fund for Nature, the territory of the Czech Republic can be subdivided into four ecoregions: the Western European broadleaf forests, Central European mixed forests, Pannonian mixed forests, and Carpathian montane conifer forests.
|
There are four national parks in the Czech Republic. The oldest is Krkonoše National Park (Biosphere Reserve), and the others are Šumava National Park (Biosphere Reserve), Podyjí National Park, and Bohemian Switzerland.
The three historical lands of the Czech Republic (formerly some countries of the Bohemian Crown) correspond with the river basins of the Elbe and the Vltava basin for Bohemia, the Morava one for Moravia, and the Oder river basin for Czech Silesia (in terms of the Czech territory).
Climate.
The Czech Republic has a temperate climate, situated in the transition zone between the oceanic and continental climate types, with warm summers and cold, cloudy and snowy winters. The temperature difference between summer and winter is due to the landlocked geographical position.
Temperatures vary depending on the elevation. In general, at higher altitudes, the temperatures decrease and precipitation increases. The wettest area in the Czech Republic is found around Bílý Potok in Jizera Mountains and the driest region is the Louny District to the northwest of Prague. Another factor is the distribution of the mountains.
|
At the highest peak of Sněžka (), the average temperature is , whereas in the lowlands of the South Moravian Region, the average temperature is as high as . The country's capital, Prague, has a similar average temperature, although this is influenced by urban factors.
The coldest month is usually January, followed by February and December. During these months, there is snow in the mountains and sometimes in the cities and lowlands. During March, April, and May, the temperature usually increases, especially during April, when the temperature and weather tends to vary during the day. Spring is also characterized by higher water levels in the rivers, due to melting snow with occasional flooding.
The warmest month of the year is July, followed by August and June. On average, summer temperatures are about higher than during winter. Summer is also characterized by rain and storms.
Autumn generally begins in September, which is still warm and dry. During October, temperatures usually fall below or and deciduous trees begin to shed their leaves. By the end of November, temperatures usually range around the freezing point.
|
The coldest temperature ever measured was in Litvínovice near České Budějovice in 1929, at and the hottest measured, was at in Dobřichovice in 2012.
Most rain falls during the summer. Sporadic rainfall is throughout the year (in Prague, the average number of days per month experiencing at least of rain varies from 12 in September and October to 16 in November) but concentrated rainfall (days with more than per day) are more frequent in the months of May to August (average around two such days per month). Severe thunderstorms, producing damaging straight-line winds, hail, and occasional tornadoes occur, especially during the summer period.
Biodiversity and conservation.
As of 2020, the Czech Republic ranks as the 21st most environmentally conscious country in the world in Environmental Performance Index. It had a 2018 Forest Landscape Integrity Index mean score of 1.71/10, ranking it 160th globally out of 172 countries. The Czech Republic has four National Parks (Šumava National Park, Krkonoše National Park, České Švýcarsko National Park, Podyjí National Park) and 25 Protected Landscape Areas. The fauna of the Czech Republic includes a wide variety of animal species. Some species (especially endangered ones) are bred in reserves. Among the rare animals are, for example, eagles, ospreys, bustards, and storks.

Government and politics.
The Czech Republic is a pluralist multi-party parliamentary representative democracy. The Parliament ("Parlament České republiky") is bicameral, with the Chamber of Deputies (, 200 members) and the Senate (, 81 members). The members of the Chamber of Deputies are elected for a four-year term by proportional representation, with a 5% election threshold. There are 14 voting districts, identical to the country's administrative regions. The Chamber of Deputies, the successor to the Czech National Council, has the powers and responsibilities of the now defunct federal parliament of the former Czechoslovakia. The members of the Senate are elected in single-seat constituencies by two-round runoff voting for a six-year term, with one-third elected every even year in the autumn. This arrangement is modeled on the U.S. Senate, but each constituency is roughly the same size and the voting system used is a two-round runoff.
The president is a formal head of state with limited and specific powers, who appoints the prime minister, as well the other members of the cabinet on a proposal by the prime minister. From 1993 until 2012, the President of the Czech Republic was selected by a joint session of the parliament for a five-year term, with no more than two consecutive terms (Václav Havel and Václav Klaus were both elected twice). Since 2013, the president has been elected directly. Some commentators have argued that, with the introduction of direct election of the President, the Czech Republic has moved away from the parliamentary system and towards a semi-presidential one. The Government's exercise of executive power derives from the Constitution. The members of the government are the Prime Minister, Deputy prime ministers and other ministers. The Government is responsible to the Chamber of Deputies. The Prime Minister is the head of government and wields powers such as the right to set the agenda for most foreign and domestic policy and choose government ministers.

Law.
The Czech Republic is a unitary state, with a civil law system based on the continental type, rooted in Germanic legal culture. The basis of the legal system is the Constitution of the Czech Republic adopted in 1993. The Penal Code is effective from 2010. A new Civil code became effective in 2014. The court system includes district, county, and supreme courts and is divided into civil, criminal, and administrative branches. The Czech judiciary has a triumvirate of supreme courts. The Constitutional Court consists of 15 constitutional judges and oversees violations of the Constitution by either the legislature or by the government. The Supreme Court is formed of 67 judges and is the court of highest appeal for most legal cases heard in the Czech Republic. The Supreme Administrative Court decides on issues of procedural and administrative propriety. It also has jurisdiction over certain political matters, such as the formation and closure of political parties, jurisdictional boundaries between government entities, and the eligibility of persons to stand for public office. The Supreme Court and the Supreme Administrative Court are both based in Brno, as is the Supreme Public Prosecutor's Office.

The President of the Czech Republic is Commander-in-chief of the armed forces. In 2004 the army transformed itself into a fully professional organization and compulsory military service was abolished. The country has been a member of NATO since 12 March 1999. Defence spending is approximately 1.28% of the GDP (2021). The armed forces are charged with protecting the Czech Republic and its allies, promoting global security interests, and contributing to NATO.

Administrative divisions.
Since 2000, the Czech Republic has been divided into thirteen regions (Czech: "kraje", singular "kraj") and the capital city of Prague. Every region has its own elected regional assembly and a regional governor. In Prague, the assembly and presidential powers are executed by the city council and the mayor.
The older seventy-six districts ("okresy", singular "okres") including three "statutory cities" (without Prague, which had special status) lost most of their importance in 1999 in an administrative reform; they remain as territorial divisions and seats of various branches of state administration.
The smallest administrative units are "obce" (municipalities). As of 2021, the Czech Republic is divided into 6,254 municipalities. Cities and towns are also municipalities. The capital city of Prague is a region and municipality at the same time.
Economy.
The Czech Republic has a developed, high-income export-oriented social market economy based in services, manufacturing and innovation, that maintains a welfare state and the European social model. The Czech Republic participates in the European Single Market as a member of the European Union and is therefore a part of the economy of the European Union, but uses its own currency, the Czech koruna, instead of the euro. It has a per capita GDP rate that is 91% of the EU average and is a member of the OECD. Monetary policy is conducted by the Czech National Bank, whose independence is guaranteed by the Constitution. The Czech Republic ranks 12th in the UN inequality-adjusted human development and 24th in World Bank Human Capital Index. It was described by "The Guardian" as "one of Europe's most flourishing economies".

Energy.
Production of Czech electricity exceeds consumption by about 10 TWh per year, the excess being exported. Nuclear power presently provides about 30 percent of the total power needs, its share is projected to increase to 40 percent. In 2005, 65.4 percent of electricity was produced by steam and combustion power plants (mostly coal); 30 percent by nuclear plants; and 4.6 percent came from renewable sources, including hydropower. The largest Czech power resource is Temelín Nuclear Power Station, with another nuclear power plant in Dukovany.
The Czech Republic is reducing its dependence on highly polluting low-grade brown coal as a source of energy. Natural gas is purchased from Norwegian companies and as liquefied gas LNG from the Netherlands and Belgium. In the past, three-quarters of gas supplies came from Russia, but after the start of the 2022 Russian invasion of Ukraine, the government gradually stopped these supplies. Gas consumption (approx. 100 TWh in 2003–2005) is almost double electricity consumption. South Moravia has small oil and gas deposits.

Communications and IT.
The Czech Republic ranks in the top 10 countries worldwide with the fastest average internet speed. By the beginning of 2008, there were over 800 mostly local WISPs, with about 350,000 subscribers in 2007. Plans based on either GPRS, EDGE, UMTS or CDMA2000 are being offered by all three mobile phone operators (T-Mobile, O2, Vodafone) and internet provider U:fon. Government-owned Český Telecom slowed down broadband penetration. At the beginning of 2004, local-loop unbundling began and alternative operators started to offer ADSL and also SDSL. This and later privatization of Český Telecom helped drive down prices.
On 1 July 2006, Český Telecom was acquired by globalized company (Spain-owned) Telefónica group and adopted the new name Telefónica O2 Czech Republic. , VDSL and ADSL2+ are offered in variants, with download speeds of up to 50 Mbit/s and upload speeds of up to 5 Mbit/s. Cable internet is gaining more popularity with its higher download speeds ranging from 50 Mbit/s to 1 Gbit/s.

The industry employs more than 110,000 people – over 1% of the population.
Guidebooks and tourists reporting overcharging by taxi drivers and pickpocketing problems talk mainly about Prague, though the situation has improved recently. Since 2005, Prague's mayor, Pavel Bém, has worked to improve this reputation by cracking down on petty crime and, aside from these problems, Prague is a "safe" city. The Czech Republic's crime rate is described by the United States State department as "low".

Historically, the Czech lands, especially Prague, have been the seat of scientific discovery going back to early modern times, including Tycho Brahe, Nicolaus Copernicus, and Johannes Kepler. In 1784 the scientific community was first formally organized under the charter of the Royal Czech Society of Sciences. Currently, this organization is known as the Czech Academy of Sciences. Similarly, the Czech lands have a well-established history of scientists, including Nobel laureates biochemists Gerty and Carl Ferdinand Cori, chemists Jaroslav Heyrovský (inventor of polarography, electroanalytical chemistry and recipient of the Nobel Prize) and Otto Wichterle (chemists responsible for the invention of the modern contact lens and silon-synthetic fiber), physicists Ernst Mach (physicist and critic of Newton's theories of space and time, foreshadowing Einstein's theory of relativity) and Peter Grünberg, physiologist Jan Evangelista Purkyně and chemist Antonín Holý (scientist and chemist, in 2009 was involved in creation of the most effective drug in the treatment of AIDS), Sigmund Freud, the founder of psychoanalysis, was born in Příbor, Gregor Mendel, the founder of genetics, was born in Hynčice and spent most of his life in Brno, logician and mathematician Kurt Gödel was born in Brno.

The current important scientific institution is the already mentioned Academy of Sciences of the Czech Republic, the CEITEC Institute in Brno or the HiLASE and Eli Beamlines centers with the most powerful laser in the world in Dolní Břežany. Prague is the seat of the administrative center of the GSA Agency operating the European navigation system Galileo and the European Union Agency for the Space Programme.
Demographics.
The total fertility rate (TFR) in 2020 was estimated at 1.71 children per woman, which is below the replacement rate of 2.1. The Czech Republic's population has an average age of 43.3 years. The life expectancy in 2021 was estimated to be 79.5 years (76.55 years male, 82.61 years female). About 77,000 people immigrate to the Czech Republic annually. Vietnamese immigrants began settling in the country during the Communist period, when they were invited as guest workers by the Czechoslovak government. In 2009, there were about 70,000 Vietnamese in the Czech Republic. Most have decided to stay in the country permanently.

According to results of the 2021 census, the majority of the inhabitants of the Czech Republic are Czechs (57.3%), followed by Moravians (3.4%), Slovaks (0.9%), Ukrainians (0.7%), Viets (0.3%), Poles (0.3%), Russians (0.2%), Silesians (0.1%) and Germans (0.1%). Another 4.0% declared a combination of two nationalities (3.6% combination of Czech and other nationality). As the 'nationality' was an optional item, a number of people left this field blank (31.6%). According to some estimates, there are about 250,000 Romani people in the Czech Republic. The Polish minority resides mainly in the Trans-Olza region.
There were 658,564 foreigners residing in the country in 2021, according to the Czech Statistical Office, with the largest groups being Ukrainian (22%), Slovak (22%), Vietnamese (12%), Russian (7%) and German (4%).

Nationality of residents, who answered the question in the Census 2021:
Religion.
About 75% to 79% of residents of the Czech Republic do not declare having any religion or faith in surveys, and the proportion of convinced atheists (30%) is the third highest in the world behind those of China (47%) and Japan (31%). The Czech people have been historically characterized as "tolerant and even indifferent towards religion". The religious identity of the country has changed drastically since the first half of the 20th century, when more than 90% of Czechs were Christians.
Christianization in the 9th and 10th centuries introduced Christianity. After the Bohemian Reformation, most Czechs became followers of Jan Hus, Petr Chelčický and other regional Protestant Reformers. Taborites and Utraquists were Hussite groups. Towards the end of the Hussite Wars, the Utraquists changed sides and allied with the Roman Catholic Church. Following the joint Utraquist—Roman Catholic victory, Utraquism was accepted as a distinct form of Christianity to be practiced in Bohemia by the Roman Catholic Church while all remaining Hussite groups were prohibited. |
Following the joint Utraquist—Roman Catholic victory, Utraquism was accepted as a distinct form of Christianity to be practiced in Bohemia by the Roman Catholic Church while all remaining Hussite groups were prohibited. After the Reformation, some Bohemians went with the teachings of Martin Luther, especially Sudeten Germans. In the wake of the Reformation, Utraquist Hussites took a renewed increasingly anti-Catholic stance, while some of the defeated Hussite factions were revived. After the Habsburgs regained control of Bohemia, the whole population was forcibly converted to Roman Catholicism—even the Utraquist Hussites. Going forward, Czechs have become more wary and pessimistic of religion as such. A history of resistance to the Roman Catholic Church followed. It suffered a schism with the neo-Hussite Czechoslovak Hussite Church in 1920, lost the bulk of its adherents during the Communist era and continues to lose in the modern, ongoing secularization. |
According to the 2011 census, 34% of the population stated they had no religion, 10.3% were Roman Catholic, 0.8% were Protestant (0.5% Czech Brethren and 0.4% Hussite), and 9% followed other forms of religion both denominational or not (of which 863 people answered they are Pagan). 45% of the population did not answer the question about religion. From 1991 to 2001 and further to 2011 the adherence to Roman Catholicism decreased from 39% to 27% and then to 10%; Protestantism similarly declined from 3.7% to 2% and then to 0.8%. The Muslim population is estimated to be 20,000 representing 0.2% of the population.
The proportion of religious believers varies significantly across the country, from 55% in Zlín Region to 16% in Ústí nad Labem Region.
Education and health care.
Education in the Czech Republic is compulsory for nine years and citizens have access to a free-tuition university education, while the average number of years of education is 13.1. Additionally, the Czech Republic has a "relatively equal" educational system in comparison with other countries in Europe. Founded in 1348, Charles University was the first university in Central Europe. Other major universities in the country are Masaryk University, Czech Technical University, Palacký University, Academy of Performing Arts and University of Economics.
|
The Programme for International Student Assessment, coordinated by the OECD, currently ranks the Czech education system as the 15th most successful in the world, higher than the OECD average. The UN Education Index ranks the Czech Republic 10th (positioned behind Denmark and ahead of South Korea).
Health care in the Czech Republic is similar in quality to that of other developed nations. The Czech universal health care system is based on a compulsory insurance model, with fee-for-service care funded by mandatory employment-related insurance plans. According to the 2016 Euro health consumer index, a comparison of healthcare in Europe, the Czech healthcare is 13th, ranked behind Sweden and two positions ahead of the United Kingdom.
Culture.
Art.
Venus of Dolní Věstonice is an important example of prehistoric art unearthed in the Czech Republic. Theodoric of Prague was a painter in the Gothic era who decorated the castle Karlštejn. In the Baroque era, there were painters Wenceslaus Hollar, Jan Kupecký, Karel Škréta, Anton Raphael Mengs and Petr Brandl and sculptors Matthias Braun and Ferdinand Brokoff.
|
In the first half of the 19th century, Josef Mánes joined the romantic movement. In the second half the so-called "National Theatre generation" rose to prominence: sculptor Josef Václav Myslbek and painters Mikoláš Aleš, Václav Brožík, Vojtěch Hynais and Julius Mařák. At the end of the century came Art Nouveau, with Alfons Mucha becoming its main representative. He is known for his Art Nouveau posters and a cycle of 20 large canvases named the Slav Epic, which depicts the history of Czechs and other Slavs. , it can be seen in the Veletržní Palace of the National Gallery in Prague, which manages the largest collection of art in the Czech Republic. Max Švabinský was another Art Nouveau painter.
The 20th century brought an avant-garde revolution, represented in the Czech lands mainly by expressionists and cubists: Josef Čapek, Emil Filla, Bohumil Kubišta or Jan Zrzavý. Surrealism emerged particularly through the work of Toyen, Josef Šíma and Karel Teige. In the world, however, the most well-known Czech avant-garde artist might be František Kupka, a pioneer of abstract painting. Illustrators and cartoonists to gain fame in the first half of the 20th century include Josef Lada, Zdeněk Burian or Emil Orlík. Art photography became a new field represented by František Drtikol, Josef Sudek, later Jan Saudek and Josef Koudelka.

The Czech Republic is also known for its individually made, mouth-blown, and decorated Bohemian glass.
Architecture.
The earliest preserved stone buildings in Bohemia and Moravia date back to the time of the Christianization in the 9th and 10th centuries. Since the Middle Ages, the Czech lands have been using the same architectural styles as most of Western and Central Europe. The oldest still standing churches were built in the Romanesque style. During the 13th century, it was replaced by the Gothic style. In the 14th century, Emperor Charles IV invited architects from France and Germany, Matthias of Arras and Peter Parler, to his court in Prague. During the Middle Ages, some fortified castles were built by the king and aristocracy, as well as some monasteries.
The Renaissance style penetrated the Bohemian Crown in the late 15th century when the older Gothic style started to be mixed with Renaissance elements. An example of pure Renaissance architecture in Bohemia is the Queen Anne's Summer Palace, which was situated in the garden of Prague Castle. Evidence of the general reception of the Renaissance in Bohemia, involving an influx of Italian architects, can be found in spacious chateaus with arcade courtyards and geometrically arranged gardens. Emphasis was placed on comfort, and buildings that were built for entertainment purposes also appeared.
|
In the 17th century, the Baroque style spread throughout the Crown of Bohemia.
In the 18th century, Bohemia produced an architectural peculiarity – the "Baroque Gothic style", a synthesis of the Gothic and Baroque styles.
During the 19th century stands the revival architectural styles. Some churches were restored to their presumed medieval appearance and there were constructed buildings in the Neo-Romanesque, Neo-Gothic and Neo-Renaissance styles. At the turn of the 19th and 20th centuries, the new art style appeared in the Czech lands – Art Nouveau.
Bohemia contributed an unusual style to the world's architectural heritage when Czech architects attempted to transpose the Cubism of painting and sculpture into architecture.
Between World Wars I and II, Functionalism, with its sober, progressive forms, took over as the main architectural style.
After World War II and the Communist coup in 1948, art in Czechoslovakia became Soviet-influenced. The Czechoslovak avant-garde artistic movement is known as the "Brussels style came up" in the time of political liberalization of Czechoslovakia in the 1960s. Brutalism dominated in the 1970s and 1980s.
|
The Czech Republic is not shying away from the more modern trends of international architecture, an example is the Dancing House (Tančící dům) in Prague, Golden Angel in Prague or Congress Centre in Zlín.
Literature.
The literature from the area of today's Czech Republic was mostly written in Czech, but also in Latin and German or even Old Church Slavonic. Franz Kafka, although a competent user of Czech, wrote in his mother tongue, German. His works include "The Trial" and "The Castle".
In the second half of the 13th century, the royal court in Prague became one of the centers of German Minnesang and courtly literature. The Czech German-language literature can be seen in the first half of the 20th century.
Bible translations played a role in the development of Czech literature. The oldest Czech translation of the Psalms originated in the late 13th century and the first complete Czech translation of the Bible was finished around 1360. The first complete printed Czech Bible was published in 1488. The first complete Czech Bible translation from the original languages was published between 1579 and 1593. The Codex Gigas from the 12th century is the largest extant medieval manuscript in the world.
|
Czech-language literature can be divided into several periods: the Middle Ages; the Hussite period; the Renaissance humanism; the Baroque period; the Enlightenment and Czech reawakening in the first half of the 19th century, modern literature in the second half of the 19th century; the avant-garde of the interwar period; the years under Communism; and the Czech Republic.
The antiwar comedy novel "The Good Soldier Švejk" is the most translated Czech book in history.
The international literary award the Franz Kafka Prize is awarded in the Czech Republic.
The Czech Republic has the densest network of libraries in Europe.
Czech literature and culture played a role on at least two occasions when Czechs lived under oppression and political activity was suppressed. On both of these occasions, in the early 19th century and then again in the 1960s, the Czechs used their cultural and literary effort to strive for political freedom, establishing a confident, politically aware nation.
Music.
The musical tradition of the Czech lands arose from the first church hymns, whose first evidence is suggested at the break of the 10th and 11th centuries. Some pieces of Czech music include two chorales, which in their time performed the function of anthems: "Lord, Have Mercy on Us" and the hymn "Saint Wenceslaus" or "Saint Wenceslaus Chorale". The authorship of the anthem "Lord, Have Mercy on Us" is ascribed by some historians to Saint Adalbert of Prague (sv.Vojtěch), bishop of Prague, living between 956 and 997.
|
The wealth of musical culture lies in the classical music tradition during all historical periods, especially in the Baroque, Classicism, Romantic, modern classical music and in the traditional folk music of Bohemia, Moravia and Silesia. Since the early era of artificial music, Czech musicians and composers have been influenced the folk music of the region and dance.
Czech music can be considered to have been "beneficial" in both the European and worldwide context, several times co-determined or even determined a newly arriving era in musical art, above all of Classical era, as well as by original attitudes in Baroque, Romantic and modern classical music. Some Czech musical works are "The Bartered Bride", "New World Symphony", "Sinfonietta" and "Jenůfa".
A music festival in the country is Prague Spring International Music Festival of classical music, a permanent showcase for performing artists, symphony orchestras and chamber music ensembles of the world.
Theatre.
The roots of Czech theatre can be found in the Middle Ages, especially in the cultural life of the Gothic period. In the 19th century, the theatre played a role in the national awakening movement and later, in the 20th century, it became a part of modern European theatre art. The original Czech cultural phenomenon came into being at the end of the 1950s. This project called Laterna magika, resulting in productions that combined theater, dance, and film in a poetic manner, considered the first multimedia art project in an international context.
|
One drama is Karel Čapek's play "R.U.R.", which introduced the word "robot".
The country has a tradition of puppet theater. In 2016, Czech and Slovak Puppetry was included on the UNESCO Intangible Cultural Heritage Lists.
Film.
The tradition of Czech cinematography started in the second half of the 1890s. Peaks of the production in the era of silent movies include the historical drama "The Builder of the Temple" and the social and erotic drama "Erotikon" directed by Gustav Machatý. The early Czech sound film era was productive, above all in mainstream genres, with the comedies of Martin Frič or Karel Lamač. There were dramatic movies sought internationally.
Hermína Týrlová was a prominent Czech animator, screenwriter, and film director. She was often called the mother of Czech animation. Over the course of her career, she produced over 60 animated children's short films using puppets and the technique of stop motion animation.
Before the German occupation, in 1933, filmmaker and animator established the first Czech animation studio "IRE Film" with her husband Karel Dodal.
|
After the period of Nazi occupation and early communist official dramaturgy of socialist realism in movies at the turn of the 1940s and 1950s with fewer exceptions such as "Krakatit" or "Men without wings" (awarded by in 1946), an era of the Czech film began with animated films, performed in anglophone countries under the name "The Fabulous World of Jules Verne" from 1958, which combined acted drama with animation, and Jiří Trnka, the founder of the modern puppet film. This began a tradition of animated films ("Mole" etc.).
In the 1960s, the hallmark of Czechoslovak New Wave's films were improvised dialogues, black and absurd humor and the occupation of non-actors. Directors are trying to preserve natural atmosphere without refinement and artificial arrangement of scenes. A personality of the 1960s and the beginning of the 1970s with original manuscript and psychological impact is František Vláčil. Another international author is Jan Švankmajer, a filmmaker and artist whose work spans several media. He is a self-labeled surrealist known for animations and features.

Czech beer has a history extending more than a millennium; the earliest known brewery existed in 993. Today, the Czech Republic has the highest beer consumption per capita in the world. The pilsner style beer (pils) originated in Plzeň, where the world's first blond lager Pilsner Urquell is still produced. It has served as the inspiration for more than two-thirds of the beer produced in the world today. The city of České Budějovice has similarly lent its name to its beer, known as Budweiser Budvar.
The South Moravian region has been producing wine since the Middle Ages; about 94% of vineyards in the Czech Republic are Moravian. Aside from beer, slivovitz and wine, the Czech Republic also produces two liquors, Fernet Stock and Becherovka.

The Škoda Motorsport is engaged in competition racing since 1901 and has gained a number of titles with various vehicles around the world. MTX automobile company was formerly engaged in the manufacture of racing and formula cars since 1969.
Hiking is a popular sport. The word for 'tourist' in Czech, "turista", also means 'trekker' or 'hiker'. For hikers, thanks to the more than 120-year-old tradition, there is the Czech Hiking Markers System of trail blazing, that has been adopted by countries worldwide. There is a network of around 40,000 km of marked short- and long-distance trails crossing the whole country and all the Czech mountains. |
Czechoslovakia
Czechoslovakia ( ; Czech and , "Česko-Slovensko") was a landlocked country in Central Europe, created in 1918, when it declared its independence from Austria-Hungary. In 1938, after the Munich Agreement, the Sudetenland became part of Nazi Germany, while the country lost further territories to Hungary and Poland (the territories of southern Slovakia with a predominantly Hungarian population to Hungary and Zaolzie with a predominantly Polish population to Poland). Between 1939 and 1945, the state ceased to exist, as Slovakia proclaimed its independence and Carpathian Ruthenia became part of Hungary, while the German Protectorate of Bohemia and Moravia was proclaimed in the remainder of the Czech Lands. In 1939, after the outbreak of World War II, former Czechoslovak President Edvard Beneš formed a government-in-exile and sought recognition from the Allies.
After World War II, Czechoslovakia was reestablished under its pre-1938 borders, with the exception of Carpathian Ruthenia, which became part of the Ukrainian SSR (a republic of the Soviet Union). The Communist Party seized power in a coup in 1948. From 1948 to 1989, Czechoslovakia was part of the Eastern Bloc with a planned economy. Its economic status was formalized in membership of Comecon from 1949 and its defense status in the Warsaw Pact of 1955. A period of political liberalization in 1968, the Prague Spring, ended when the Soviet Union, assisted by other Warsaw Pact countries, invaded Czechoslovakia. In 1989, as Marxist–Leninist governments and communism were ending all over Central and Eastern Europe, Czechoslovaks peacefully deposed their communist government during the Velvet Revolution, which began on 17 November 1989 and ended 11 days later on 28 November when all of the top Communist leaders and Communist party itself resigned. On 31 December 1992, Czechoslovakia peacefully split into the two sovereign states of the Czech Republic and Slovakia.
|
Characteristics.
The country was of generally irregular terrain. The western area was part of the north-central European uplands. The eastern region was composed of the northern reaches of the Carpathian Mountains and lands of the Danube River basin.
The weather was characterized by mild to cold winters and mild to warm summers, influenced by the Atlantic Ocean from the west, the Baltic Sea from the north, and Mediterranean Sea from the south. The country was situated in the transition zone between the oceanic and continental climate types.
History.
Origins.
The area was part of the Austro-Hungarian Empire until it collapsed at the end of World War I. The new state was founded by Tomáš Garrigue Masaryk, who served as its first president from 14 November 1918 to 14 December 1935. He was succeeded by his close ally Edvard Beneš (1884–1948).
The roots of Czech nationalism go back to the 19th century, when philologists and educators, influenced by Romanticism, promoted the Czech language and pride in the Czech people. Nationalism became a mass movement in the second half of the 19th century. Taking advantage of the limited opportunities for participation in political life under Austrian rule, Czech leaders such as historian František Palacký (1798–1876) founded various patriotic self-help organizations which provided a chance for many of their compatriots to participate in communal life before independence. Palacký supported Austro-Slavism and worked for a reorganized federal Austrian Empire, which would protect the Slavic speaking peoples of Central Europe against Russian and German threats.
|
An advocate of democratic reform and Czech autonomy within Austria-Hungary, Masaryk was elected twice to the "Reichsrat" (Austrian Parliament), from 1891 to 1893 for the Young Czech Party, and from 1907 to 1914 for the Czech Realist Party, which he had founded in 1889 with Karel Kramář and Josef Kaizl.
During World War I a number of Czechs and Slovaks, the Czechoslovak Legions, fought with the Allies in France and Italy, while large numbers deserted to Russia in exchange for its support for the independence of Czechoslovakia from the Austrian Empire. With the outbreak of World War I, Masaryk began working for Czech independence in a union with Slovakia. With Edvard Beneš and Milan Rastislav Štefánik, Masaryk visited several Western countries and won support from influential publicists. The Czechoslovak National Council was the main organization that advanced the claims for a Czechoslovak state.
First Czechoslovak Republic.
Formation.
The Bohemian Kingdom ceased to exist in 1918 when it was incorporated into Czechoslovakia. Czechoslovakia was founded in October 1918, as one of the successor states of the Austro-Hungarian Empire at the end of World War I and as part of the Treaty of Saint-Germain-en-Laye. It consisted of the present-day territories of Bohemia, Moravia, parts of Silesia making up present-day Czech Republic, Slovakia, and a region of present-day Ukraine called Carpathian Ruthenia. Its territory included some of the most industrialized regions of the former Austria-Hungary.
|
Ethnicity.
The new country was a multi-ethnic state, with Czechs and Slovaks as "constituent peoples". The population consisted of Czechs (51%), Slovaks (16%), Germans (22%), Hungarians (5%) and Rusyns (4%). Many of the Germans, Hungarians, Ruthenians and Poles and some Slovaks, felt oppressed because the political elite did not generally allow political autonomy for minority ethnic groups. This policy led to unrest among the non-Czech population, particularly in German-speaking Sudetenland, which initially had proclaimed itself part of the Republic of German-Austria in accordance with the self-determination principle.
The state proclaimed the official ideology that there were no separate Czech and Slovak nations, but only one nation of Czechoslovaks (see Czechoslovakism), to the disagreement of Slovaks and other ethnic groups. Once a unified Czechoslovakia was restored after World War II (after the country had been divided during the war), the conflict between the Czechs and the Slovaks surfaced again. The governments of Czechoslovakia and other Central European nations deported ethnic Germans, reducing the presence of minorities in the nation. Most of the Jews had been killed during the war by the Nazis.
|
Interwar period.
During the period between the two world wars Czechoslovakia was a democratic state. The population was generally literate, and contained fewer alienated groups. The influence of these conditions was augmented by the political values of Czechoslovakia's leaders and the policies they adopted. Under Tomas Masaryk, Czech and Slovak politicians promoted progressive social and economic conditions that served to defuse discontent.
Foreign minister Beneš became the prime architect of the Czechoslovak-Romanian-Yugoslav alliance (the "Little Entente", 1921–38) directed against Hungarian attempts to reclaim lost areas. Beneš worked closely with France. Far more dangerous was the German element, which after 1933 became allied with the Nazis in Germany.
Czech-Slovak relations came to be a central issue in Czechoslovak politics during the 1930s. The increasing feeling of inferiority among the Slovaks, who were hostile to the more numerous Czechs, weakened the country in the late 1930s. Slovakia became autonomous in the fall of 1938, and by mid-1939, Slovakia had become independent, with the First Slovak Republic set up as a satellite state of Nazi Germany and the far-right Slovak People's Party in power .
|
After 1933, Czechoslovakia remained the only democracy in central and eastern Europe.
Munich Agreement, and Two-Step German Occupation.
In September 1938, Adolf Hitler demanded control of the Sudetenland. On 29 September 1938, Britain and France ceded control in the Appeasement at the Munich Conference; France ignored the military alliance it had with Czechoslovakia. During October 1938, Nazi Germany occupied the Sudetenland border region, effectively crippling Czechoslovak defences.
The First Vienna Award assigned a strip of southern Slovakia and Carpathian Ruthenia to Hungary. Poland occupied Zaolzie, an area whose population was majority Polish, in October 1938.
On 14 March 1939, the remainder ("rump") of Czechoslovakia was dismembered by the proclamation of the Slovak State, the next day the rest of Carpathian Ruthenia was occupied and annexed by Hungary, while the following day the German Protectorate of Bohemia and Moravia was proclaimed.
The eventual goal of the German state under Nazi leadership was to eradicate Czech nationality through assimilation, deportation, and extermination of the Czech intelligentsia; the intellectual elites and middle class made up a considerable number of the 200,000 people who passed through concentration camps and the 250,000 who died during German occupation. Under , it was assumed that around 50% of Czechs would be fit for Germanization. The Czech intellectual elites were to be removed not only from Czech territories but from Europe completely. The authors of believed it would be best if they emigrated overseas, as even in Siberia they were considered a threat to German rule. Just like Jews, Poles, Serbs, and several other nations, Czechs were considered to be untermenschen by the Nazi state. In 1940, in a secret Nazi plan for the Germanization of the Protectorate of Bohemia and Moravia it was declared that those considered to be of racially Mongoloid origin and the Czech intelligentsia were not to be Germanized.
|
The deportation of Jews to concentration camps was organized under the direction of Reinhard Heydrich, and the fortress town of Terezín was made into a ghetto way station for Jewish families. On 4 June 1942 Heydrich died after being wounded by an assassin in Operation Anthropoid. Heydrich's successor, Colonel General Kurt Daluege, ordered mass arrests and executions and the destruction of the villages of Lidice and Ležáky. In 1943 the German war effort was accelerated. Under the authority of Karl Hermann Frank, German minister of state for Bohemia and Moravia, some 350,000 Czech laborers were dispatched to the Reich. Within the protectorate, all non-war-related industry was prohibited. Most of the Czech population obeyed quiescently up until the final months preceding the end of the war, while thousands were involved in the resistance movement.
For the Czechs of the Protectorate Bohemia and Moravia, German occupation was a period of brutal oppression. Czech losses resulting from political persecution and deaths in concentration camps totaled between 36,000 and 55,000. The Jewish populations of Bohemia and Moravia (118,000 according to the 1930 census) were virtually annihilated. Many Jews emigrated after 1939; more than 70,000 were killed; 8,000 survived at Terezín. Several thousand Jews managed to live in freedom or in hiding throughout the occupation.
|
Despite the estimated 136,000 deaths at the hands of the Nazi regime, the population in the Reichsprotektorate saw a net increase during the war years of approximately 250,000 in line with an increased birth rate.
On 6 May 1945, the third US Army of General Patton entered Plzeň from the south west. On 9 May 1945, Soviet Red Army troops entered Prague.
Third and Fourth Republics.
After World War II, pre-war Czechoslovakia was reestablished, with the exception of Subcarpathian Ruthenia, which was annexed by the Soviet Union and incorporated into the Ukrainian Soviet Socialist Republic. The Beneš decrees were promulgated concerning ethnic Germans (see Potsdam Agreement) and ethnic Hungarians. Under the decrees, citizenship was abrogated for people of German and Hungarian ethnic origin who had accepted German or Hungarian citizenship during the occupations. In 1948, this provision was cancelled for the Hungarians, but only partially for the Germans. The government then confiscated the property of the Germans and expelled about 90% of the ethnic German population, over 2 million people. Those who remained were collectively accused of supporting the Nazis after the Munich Agreement, as 97.32% of Sudeten Germans had voted for the NSDAP in the December 1938 elections. Almost every decree explicitly stated that the sanctions did not apply to antifascists. Some 250,000 Germans, many married to Czechs, some antifascists, and also those required for the post-war reconstruction of the country, remained in Czechoslovakia. The Beneš Decrees still cause controversy among nationalist groups in the Czech Republic, Germany, Austria and Hungary.
|
Following the expulsion of the ethnic German population from Czechoslovakia, parts of the former Sudetenland, especially around Krnov and the surrounding villages of the Jeseníky mountain region (Nízký Jeseník and Hrubý Jeseník) in northeastern Czechoslovakia, were settled in 1949 by Communist refugees from Northern Greece who had left their homeland as a result of the Greek Civil War. These Greeks made up a large proportion of the town and region's population until the late 1980s/early 1990s. Although defined as "Greeks", the Greek Communist community of Krnov and the Jeseníky region actually consisted of an ethnically diverse population, including Greek Macedonians, Macedonians, Vlachs, Pontic Greeks and Turkish speaking Urums or Caucasus Greeks.
Carpathian Ruthenia (Podkarpatská Rus) was occupied by (and in June 1945 formally ceded to) the Soviet Union. In the 1946 parliamentary election, the Communist Party of Czechoslovakia was the winner in the Czech lands, and the Democratic Party won in Slovakia. In February 1948 the Communists seized power. Although they would maintain the fiction of political pluralism through the existence of the National Front, except for a short period in the late 1960s (the Prague Spring) the country had no liberal democracy. Since citizens lacked significant electoral methods of registering protest against government policies, periodically there were street protests that became violent. For example, there were riots in the town of Plzeň in 1953, reflecting economic discontent. Police and army units put down the rebellion, and hundreds were injured but no one was killed. While its economy remained more advanced than those of its neighbors in Eastern Europe, Czechoslovakia grew increasingly economically weak relative to Western Europe.
|
The currency reform of 1953 caused dissatisfaction among Czechoslovak laborers. To equalize the wage rate, Czechoslovaks had to turn in their old money for new at a decreased value. The banks also confiscated savings and bank deposits to control the amount of money in circulation. In the 1950s, Czechoslovakia experienced high economic growth (averaging 7% per year), which allowed for a substantial increase in wages and living standards, thus promoting the stability of the regime.
In 1968, when the reformer Alexander Dubček was appointed to the key post of First Secretary of the Czechoslovak Communist Party, there was a brief period of liberalization known as the Prague Spring. In response, after failing to persuade the Czechoslovak leaders to change course, five other members of the Warsaw Pact invaded. Soviet tanks rolled into Czechoslovakia on the night of 20–21 August 1968. Soviet Communist Party General Secretary Leonid Brezhnev viewed this intervention as vital for the preservation of the Soviet, socialist system and vowed to intervene in any state that sought to replace Marxism-Leninism with capitalism.
|
In the week after the invasion, there was a spontaneous campaign of civil resistance against the occupation. This resistance involved a wide range of acts of non-cooperation and defiance: this was followed by a period in which the Czechoslovak Communist Party leadership, having been forced in Moscow to make concessions to the Soviet Union, gradually put the brakes on their earlier liberal policies.
Meanwhile, one plank of the reform program had been carried out: in 1968–69, Czechoslovakia was turned into a federation of the Czech Socialist Republic and Slovak Socialist Republic. The theory was that under the federation, social and economic inequities between the Czech and Slovak halves of the state would be largely eliminated. A number of ministries, such as education, now became two formally equal bodies in the two formally equal republics. However, the centralized political control by the Czechoslovak Communist Party severely limited the effects of federalization.
The 1970s saw the rise of the dissident movement in Czechoslovakia, represented among others by Václav Havel. The movement sought greater political participation and expression in the face of official disapproval, manifested in limitations on work activities, which went as far as a ban on professional employment, the refusal of higher education for the dissidents' children, police harassment and prison.

During the 1980s, Czechoslovakia became one of the most tightly controlled Communist regimes in the Warsaw Pact in resistance to the mitigation of controls notified by Soviet president Mikhail Gorbachev.
After 1989.
In 1989, the Velvet Revolution restored democracy. This occurred around the same time as the fall of communism in Romania, Bulgaria, Hungary, East Germany and Poland.
The word "socialist" was removed from the country's full name on 29 March 1990 and replaced by "federal".
Pope John Paul II made a papal visit to Czechoslovakia on 21 April 1990, hailing it as a symbolic step of reviving Christianity in the newly-formed post-communist state.
Czechoslovakia participated in the Gulf War with a small force of 200 troops under the command of the U.S.-led coalition.
In 1992, because of growing nationalist tensions in the government, Czechoslovakia was peacefully dissolved by parliament. On 31 December 1992, it formally separated into two independent countries, the Czech Republic and the Slovak Republic.
Government and politics.
|
After World War II, a political monopoly was held by the Communist Party of Czechoslovakia (KSČ). The leader of the KSČ was "de facto" the most powerful person in the country during this period. Gustáv Husák was elected first secretary of the KSČ in 1969 (changed to general secretary in 1971) and president of Czechoslovakia in 1975. Other parties and organizations existed but functioned in subordinate roles to the KSČ. All political parties, as well as numerous mass organizations, were grouped under umbrella of the National Front. Human rights activists and religious activists were severely repressed.
Constitutional development.
Czechoslovakia had the following constitutions during its history (1918–1992):
Foreign policy.
International agreements and membership.
In the 1930s, the nation formed a military alliance with France, which collapsed in the Munich Agreement of 1938. After World War II, an active participant in Council for Mutual Economic Assistance (Comecon), Warsaw Pact, United Nations and its specialized agencies; signatory of conference on Security and Cooperation in Europe.
|
International relations.
Between 1948 and 1949, Czechoslovakia formed a relationship with Israel through their military support during the War of 1948. Israel bought approximately US$144 million worth of weapons and ammunition.
Economy.
Before World War II, the economy was about the fourth in all industrial countries in Europe. The state was based on strong economy, manufacturing cars (Škoda, Tatra), trams, aircraft (Aero, Avia), ships, ship engines (Škoda), cannons, shoes (Baťa), turbines, guns (Zbrojovka Brno). It was the industrial workshop for the Austro-Hungarian empire. The Slovak lands relied more heavily on agriculture than the Czech lands.
After World War II, the economy was centrally planned, with command links controlled by the communist party, similarly to the Soviet Union. The large metallurgical industry was dependent on imports of iron and non-ferrous ores.
Resource base.
After World War II, the country was short of energy, relying on imported crude oil and natural gas from the Soviet Union, domestic brown coal, and nuclear and hydroelectric energy. Energy constraints were a major factor in the 1980s.
|
Transport and communications.
Slightly after the foundation of Czechoslovakia in 1918, there was a lack of essential infrastructure in many areas – paved roads, railways, bridges, etc. Massive improvement in the following years enabled Czechoslovakia to develop its industry. Prague's civil airport in Ruzyně became one of the most modern terminals in the world when it was finished in 1937. Tomáš Baťa, a Czech entrepreneur and visionary, outlined his ideas in the publication "Budujme stát pro 40 milionů lidí", where he described the future motorway system. Construction of the first motorways in Czechoslovakia begun in 1939, nevertheless, they were stopped after German occupation during World War II.
Education.
Education was free at all levels and compulsory from ages 6 to 15. The vast majority of the population was literate. There was a highly developed system of apprenticeship training and vocational schools supplemented general secondary schools and institutions of higher education.
Religion.
In 1991, 46% of the population were Roman Catholics, 5.3% were Evangelical Lutheran, 30% were Atheist, and other religions made up 17% of the country, but there were huge differences in religious practices between the two constituent republics; see Czech Republic and Slovakia.
|
Health, social welfare and housing.
After World War II, free health care was available to all citizens. National health planning emphasized preventive medicine; factory and local health care centres supplemented hospitals and other inpatient institutions. There was a substantial improvement in rural health care during the 1960s and 1970s.
Mass media.
During the era between the World Wars, Czechoslovak democracy and liberalism facilitated conditions for free publication. The most significant daily newspapers in these times were Lidové noviny, Národní listy, Český deník and Československá Republika.
During Communist rule, the mass media in Czechoslovakia were controlled by the Communist Party. Private ownership of any publication or agency of the mass media was generally forbidden, although churches and other organizations published small periodicals and newspapers. Even with this information monopoly in the hands of organizations under KSČ control, all publications were reviewed by the government's Office for Press and Information.

Sports.
The Czechoslovakia national football team was a consistent performer on the international scene, with eight appearances in the FIFA World Cup Finals, finishing in second place in 1934 and 1962. The team also won the European Football Championship in 1976, came in third in 1980, and won the Olympic gold in 1980.
Well-known football players such as Jan Koller, Pavel Nedvěd, Antonín Panenka, Milan Baroš, Tomáš Rosický, Vladimír Šmicer, Petr Čech, Ladislav Petráš, Marián Masný, Ján Pivarník, Ján Mucha, Róbert Vittek, Peter Pekarík, and Marek Hamšík were all born in Czechoslovakia.
The International Olympic Committee code for Czechoslovakia is TCH, which is still used in historical listings of results.
The Czechoslovak national ice hockey team won many medals from the world championships and Olympic Games. Peter Šťastný, Jaromír Jágr, Dominik Hašek, Peter Bondra, Petr Klíma, Marián Gáborík, Marián Hossa, Miroslav Šatan and Pavol Demitra all come from Czechoslovakia.
Emil Zátopek, winner of four Olympic gold medals in athletics, is considered one of the top athletes in Czechoslovak history.
|
Věra Čáslavská was an Olympic gold medallist in gymnastics, winning seven gold medals and four silver medals. She represented Czechoslovakia in three consecutive Olympics.
Several accomplished professional tennis players including Jaroslav Drobný, Ivan Lendl, Jan Kodeš, Miloslav Mečíř, Hana Mandlíková, Martina Hingis, Martina Navratilova, Jana Novotná, Petra Kvitová, Daniela Hantuchová, Barbora Krejčíková, Markéta Vondroušová and Karolína Muchová were born in Czechoslovakia (or what became the Czech Republic in 1993).

Computer science
Computer science is the study of computation, information, and automation. Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).
Algorithms and data structures are central to computer science.
The theory of computation concerns abstract models of computation and general classes of problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and preventing security vulnerabilities. Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of repositories of data. Human–computer interaction investigates the interfaces through which humans and computers interact, and software engineering focuses on the design and principles behind developing software. Areas such as operating systems, networks and embedded systems investigate the principles and design behind complex systems. Computer architecture describes the construction of computer components and computer-operated equipment. Artificial intelligence and machine learning aim to synthesize goal-orientated processes such as problem-solving, decision-making, environmental adaptation, planning and learning found in humans and animals. Within artificial intelligence, computer vision aims to understand and process image and video data, while natural language processing aims to understand and process textual and linguistic data.

The fundamental concern of computer science is determining what can and cannot be automated. The Turing Award is generally recognized as the highest distinction in computer science.
History.
The earliest foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks such as the abacus have existed since antiquity, aiding in computations such as multiplication and division. Algorithms for performing computations have existed since antiquity, even before the development of sophisticated computing equipment.
Wilhelm Schickard designed and constructed the first working mechanical calculator in 1623. In 1673, Gottfried Leibniz demonstrated a digital mechanical calculator, called the Stepped Reckoner. Leibniz may be considered the first computer scientist and information theorist, because of various reasons, including the fact that he documented the binary number system. In 1820, Thomas de Colmar launched the mechanical calculator industry when he invented his simplified arithmometer, the first calculating machine strong enough and reliable enough to be used daily in an office environment. |
In 1820, Thomas de Colmar launched the mechanical calculator industry when he invented his simplified arithmometer, the first calculating machine strong enough and reliable enough to be used daily in an office environment. Charles Babbage started the design of the first "automatic mechanical calculator", his Difference Engine, in 1822, which eventually gave him the idea of the first "programmable mechanical calculator", his Analytical Engine. He started developing this machine in 1834, and "in less than two years, he had sketched out many of the salient features of the modern computer". "A crucial step was the adoption of a punched card system derived from the Jacquard loom" making it infinitely programmable. In 1843, during the translation of a French article on the Analytical Engine, Ada Lovelace wrote, in one of the many notes she included, an algorithm to compute the Bernoulli numbers, which is considered to be the first published algorithm ever specifically tailored for implementation on a computer. Around 1885, Herman Hollerith invented the tabulator, which used punched cards to process statistical information; eventually his company became part of IBM. |
Around 1885, Herman Hollerith invented the tabulator, which used punched cards to process statistical information; eventually his company became part of IBM. Following Babbage, although unaware of his earlier work, Percy Ludgate in 1909 published the 2nd of the only two designs for mechanical analytical engines in history. In 1914, the Spanish engineer Leonardo Torres Quevedo published his "Essays on Automatics", and designed, inspired by Babbage, a theoretical electromechanical calculating machine which was to be controlled by a read-only program. The paper also introduced the idea of floating-point arithmetic. In 1920, to celebrate the 100th anniversary of the invention of the arithmometer, Torres presented in Paris the Electromechanical Arithmometer, a prototype that demonstrated the feasibility of an electromechanical analytical engine, on which commands could be typed and the results printed automatically.

During the 1940s, with the development of new and more powerful computing machines such as the Atanasoff–Berry computer and ENIAC, the term "computer" came to refer to the machines rather than their human predecessors. As it became clear that computers could be used for more than just mathematical calculations, the field of computer science broadened to study computation in general. In 1945, IBM founded the Watson Scientific Computing Laboratory at Columbia University in New York City. The renovated fraternity house on Manhattan's West Side was IBM's first laboratory devoted to pure science. The lab is the forerunner of IBM's Research Division, which today operates research facilities around the world. Ultimately, the close relationship between IBM and Columbia University was instrumental in the emergence of a new scientific discipline, with Columbia offering one of the first academic-credit courses in computer science in 1946. Computer science began to be established as a distinct academic discipline in the 1950s and early 1960s. The world's first computer science degree program, the Cambridge Diploma in Computer Science, began at the University of Cambridge Computer Laboratory in 1953. The first computer science department in the United States was formed at Purdue University in 1962. Since practical computers became available, many applications of computing have become distinct areas of study in their own rights.

Etymology and scope.
Although first proposed in 1956, the term "computer science" appears in a 1959 article in "Communications of the ACM",
in which Louis Fein argues for the creation of a "Graduate School in Computer Sciences" analogous to the creation of Harvard Business School in 1921. Louis justifies the name by arguing that, like management science, the subject is applied and interdisciplinary in nature, while having the characteristics typical of an academic discipline.
His efforts, and those of others such as numerical analyst George Forsythe, were rewarded: universities went on to create such departments, starting with Purdue in 1962. Despite its name, a significant amount of computer science does not involve the study of computers themselves. Because of this, several alternative names have been proposed. Certain departments of major universities prefer the term "computing science", to emphasize precisely that difference. Danish scientist Peter Naur suggested the term "datalogy", to reflect the fact that the scientific discipline revolves around data and data treatment, while not necessarily involving computers. The first scientific institution to use the term was the Department of Datalogy at the University of Copenhagen, founded in 1969, with Peter Naur being the first professor in datalogy. The term is used mainly in the Scandinavian countries. An alternative term, also proposed by Naur, is data science; this is now used for a multi-disciplinary field of data analysis, including statistics and databases.

In the early days of computing, a number of terms for the practitioners of the field of computing were suggested (albeit facetiously) in the "Communications of the ACM"—"turingineer", "turologist", "flow-charts-man", "applied meta-mathematician", and "applied epistemologist". Three months later in the same journal, "comptologist" was suggested, followed next year by "hypologist". The term "computics" has also been suggested. In Europe, terms derived from contracted translations of the expression "automatic information" (e.g. "" in Italian) or "information and mathematics" are often used, e.g. (French), (German), (Italian, Dutch), (Spanish, Portuguese), (Slavic languages and Hungarian) or (, which means informatics) in Greek. Similar words have also been adopted in the UK (as in the School of Informatics, University of Edinburgh). "In the U.S., however, informatics is linked with applied computing, or computing in the context of another domain."
A folkloric quotation, often attributed to—but almost certainly not first formulated by—Edsger Dijkstra, states that "computer science is no more about computers than astronomy is about telescopes." The design and deployment of computers and computer systems is generally considered the province of disciplines other than computer science. For example, the study of computer hardware is usually considered part of computer engineering, while the study of commercial computer systems and their deployment is often called information technology or information systems. However, there has been exchange of ideas between the various computer-related disciplines. Computer science research also often intersects other disciplines, such as cognitive science, linguistics, mathematics, physics, biology, Earth science, statistics, philosophy, and logic.

Computer science is considered by some to have a much closer relationship with mathematics than many scientific disciplines, with some observers saying that computing is a mathematical science. Early computer science was strongly influenced by the work of mathematicians such as Kurt Gödel, Alan Turing, John von Neumann, Rózsa Péter and Alonzo Church and there continues to be a useful interchange of ideas between the two fields in areas such as mathematical logic, category theory, domain theory, and algebra.
The relationship between computer science and software engineering is a contentious issue, which is further muddied by disputes over what the term "software engineering" means, and how computer science is defined. David Parnas, taking a cue from the relationship between other engineering and science disciplines, has claimed that the principal focus of computer science is studying the properties of computation in general, while the principal focus of software engineering is the design of specific computations to achieve practical goals, making the two separate but complementary disciplines.

The academic, political, and funding aspects of computer science tend to depend on whether a department is formed with a mathematical emphasis or with an engineering emphasis. Computer science departments with a mathematics emphasis and with a numerical orientation consider alignment with computational science. Both types of departments tend to make efforts to bridge the field educationally if not across all research.
Philosophy.
Epistemology of computer science.
Despite the word "science" in its name, there is debate over whether or not computer science is a discipline of science, mathematics, or engineering. Allen Newell and Herbert A. Simon argued in 1975, It has since been argued that computer science can be classified as an empirical science since it makes use of empirical testing to evaluate the correctness of programs, but a problem remains in defining the laws and theorems of computer science (if any exist) and defining the nature of experiments in computer science. Proponents of classifying computer science as an engineering discipline argue that the reliability of computational systems is investigated in the same way as bridges in civil engineering and airplanes in aerospace engineering. They also argue that while empirical sciences observe what presently exists, computer science observes what is possible to exist and while scientists discover laws from observation, no proper laws have been found in computer science and it is instead concerned with creating phenomena.
|
Proponents of classifying computer science as a mathematical discipline argue that computer programs are physical realizations of mathematical entities and programs that can be deductively reasoned through mathematical formal methods. Computer scientists Edsger W. Dijkstra and Tony Hoare regard instructions for computer programs as mathematical sentences and interpret formal semantics for programming languages as mathematical axiomatic systems.
Paradigms of computer science.
A number of computer scientists have argued for the distinction of three separate paradigms in computer science. Peter Wegner argued that those paradigms are science, technology, and mathematics. Peter Denning's working group argued that they are theory, abstraction (modeling), and design. Amnon H. Eden described them as the "rationalist paradigm" (which treats computer science as a branch of mathematics, which is prevalent in theoretical computer science, and mainly employs deductive reasoning), the "technocratic paradigm" (which might be found in engineering approaches, most prominently in software engineering), and the "scientific paradigm" (which approaches computer-related artifacts from the empirical perspective of natural sciences, identifiable in some branches of artificial intelligence).
