Czechs · Lablypedia

Ethnic Czechs were called Bohemians in English until the early 20th century, referring to the former name of their country, Bohemia, which in turn was adapted from the late Iron Age tribe of Celtic Boii. During the migration period, West Slavs of Bohemia settled in the area, assimilated the remaining population, and formed a principality which in the late 9th century, initially part of Great Moravia, became known as the Duchy of Bohemia and later Kingdom of Bohemia, the predecessors of the modern republic.

The Czech diaspora is found in notable numbers in the United States, Germany, Canada, Slovakia, Austria, the United Kingdom, Argentina, Australia, Switzerland, France, Russia, Italy, Israel, Brazil, and Romania among others.

Ethnology

The Czech ethnic group is part of the West Slavic subgroup of the larger Slavic ethno-linguistical group. The West Slavs have their origin in early Slavic tribes which settled in Central Europe after East Germanic tribes had left this area during the migration period. The West Slavic tribe of Czechs settled in the area of Bohemia during the migration period, and assimilated the remaining Celtic and Germanic populations. In the 9th century the Duchy of Bohemia, under the Přemyslid dynasty, was formed, which had been part of Great Moravia under Svatopluk I. According to mythology, the founding father of the Czech people was Forefather Čech, who according to legend brought the tribe of Czechs into its land.

The Czechs are closely related to the neighbouring Slovaks (with whom they constituted Czechoslovakia 1918–1939, 1945–1992). The Czech–Slovak languages form a dialect continuum rather than being two clearly distinct languages. Czech cultural influence in Slovak culture is noted as having been much higher than the other way around. Czech (Slavic) people have a long history of coexistence with the Germanic people. In the 17th century, German replaced Czech in central and local administration; upper classes in Bohemia and Moravia were Germanized, and espoused a political identity (Landespatriotismus), while Czech ethnic identity survived among the lower and lower-middle classes. The Czech National Revival took place in the 18th and 19th centuries aiming to revive Czech language, culture and national identity. The Czechs were the initiators of Pan-Slavism.

The Czech ethnonym (archaic Čechové) was the name of a Slavic tribe in central Bohemia that subdued the surrounding tribes in the late 9th century and created the Czech/Bohemian state. The origin of the name of the tribe itself is unknown. According to legend, it comes from their leader Čech, who brought them to Bohemia. The exact etymology of Čech is uncertain, with most common derivation relating it to the root čel- (member of the people, kinsman). The Czech ethnonym was adopted by the Moravians in the 19th century.

Genetics

Czechs, like most Europeans, largely descend from three distinct lineages: Mesolithic hunter-gatherers, descended from a Cro-Magnon population that arrived in Europe about 45,000 years ago, Neolithic farmers who migrated from Anatolia during the Neolithic Revolution 9,000 years ago, and Yamnaya steppe pastoralists who expanded into Europe from the Pontic–Caspian steppe in the context of Indo-European migrations 5000 years ago.

The population of the Czech lands has been influenced by different human migrations that wide-crossed Europe over time. In their Y-DNA haplogroups, which are inherited along the male line, Czechs have shown a mix of Eastern and Western European traits. Studies on 1750 and 257 samples found out frequenices of R1a (34.2-36.94%), R1b (24.78%-28.0%), I2 (11.3%), I1 (8.33%), E (5.1-6.63%), G (5.1%), J2 (3.5%), J1 (0-2%), and N (1.6%). The haplogroup R1a is predominantly represented by its more Western Slavic clade R1a-M458 (>30%) as more Eastern Slavic clade R-M558 is in a small minority (<6%). Based on haplotype similarity, Czechs are most similar to neighboring Slovaks, but although "a sharp genetic border was found between Poland and Germany, the frequency distribution of haplotypes in the Czech Republic and its neighbours resembles far more a smooth cline than a sharp border". A mtDNA study of 179 individuals from Western Bohemia showed that 3% had East Eurasian lineages that perhaps entered the gene pool through admixture with Central Asian nomadic tribes in the early Middle Ages.

History

The population of the Czech Republic descends from diverse peoples of Slavic, Celtic and Germanic origin. Presence of West Slavs in the 6th century during the Migration Period has been documented on the Czech territory. Slavs settled in Bohemia, Moravia and Austria sometime during the 6th or 7th centuries, and "assimilated the remaining Celtic and Germanic populations". According to a popular myth, the Slavs came with Forefather Čech who settled at the Říp Mountain.

During the 7th century, the Frankish merchant Samo, supporting the Slavs fighting against nearby settled Avars, became the ruler of the first known Slav state in Central Europe, Samo's Empire. The principality Great Moravia, controlled by the Moymir dynasty, arose in the 8th century and reached its zenith in the 9th (during the reign of Svatopluk I of Moravia) when it held off the influence of the Franks. Great Moravia was Christianized, the crucial role played Byzantine mission of Cyril and Methodius. The Duchy of Bohemia emerged in the late 9th century. In 880, Prague Castle was constructed by Prince Bořivoj, founder of the Přemyslid dynasty and the city of Prague was established. Vratislav II was the first Czech king in 1085 and the duchy was raised to a hereditary kingdom under Ottokar I in 1198.

The second half of the 13th century was a period of advancing German immigration into the Czech lands. The number of Czechs who have at least partly German ancestry today probably runs into hundreds of thousands. The Habsburg Monarchy focused much of its power on religious wars against the Protestants. While these religious wars were taking place, the Czech estates revolted against Habsburg from 1546 to 1547 but were ultimately defeated.

Defenestrations of Prague in 1618, signaled an open revolt by the Bohemian estates against the Habsburgs and started the Thirty Years' War. After the Battle of White Mountain in 1620, all Czech lands were declared hereditary property of the Habsburg family. The German language was made equal to the Czech language.

Czech patriotic authors tend to call the following period, from 1620 to 1648 until the late 18th century, the "Dark Age". It is characterized by devastation by foreign troops; Germanization; and economic and political decline. It is estimated that the population of the Czech lands declined by a third.

The 18th and 19th century is characterized by the Czech National Revival, focusing to revive Czech culture and national identity.

Since the turn of the 20th century, Chicago is the city with the third largest Czech population, after Prague and Vienna.

During World War I, Czechoslovak Legions fought in France, Italy and Russia against the Central Powers. In 1918 the independent state of Czechoslovakia was proclaimed. Czechs formed the leading class in the new state emerging from the remnants of the Austrian-Hungarian Monarchy.

After 1933, Czechoslovakia remained the only democracy in central and eastern Europe. However, in 1938 the Munich Agreement severed the Sudetenland, with a considerable Czech minority, from Czechoslovakia, and in 1939 the German Nazi regime established the Protectorate of Bohemia and Moravia for Resttschechei (the rump Czech state). Emil Hácha became president of the protectorate under Nazi domination, which only allowed pro-Nazi Czech associations and tended to stress ties of the Czechs with the Bohemian Germans and other parts of the German people, in order to facilitate assimilation by Germanization. In Lidice, Ležáky and Javoříčko the Nazi authorities committed war crimes against the local Czech population. On 2 May 1945, the Prague Uprising reached its peak, supported by the Russian Liberation Army. The post-war expulsion of Germans from Czechoslovakia and the immediate reprisals against Germans and Nazi collaborators by Czech resistance and the Czechoslovak state authorities, made Czechs—especially in the early 1950s—settle alongside Slovaks and Romani people in the former lands of the Sudeten Germans, who had been deported to East Germany, West Germany and Austria according to the Potsdam Conference and Yalta Conference.

The Warsaw Pact invasion of Czechoslovakia in 1968 was followed by a wave of emigration, unseen before and stopped shortly after in 1969 (estimate: 70,000 immediately, 300,000 in total), typically of highly qualified people.

Tens of thousands of Czechs had repatriated from Volhynia and Banat after World War II. Since the 1990s, the Czech Republic has been working to repatriate Romania and Kazakhstan's ethnic Czechs.

Jan Palach committed self-immolation as a political protest against the end of the Prague Spring resulting from the 1968 invasion of Czechoslovakia by the Warsaw Pact armies.

Another notable politician after the fall of the communist regime is Václav Havel, last President of Czechoslovakia and first President of the Czech Republic. The first directly elected president is Miloš Zeman.

The Czech Republic has had multiple Prime Ministers, the first of which were future presidents Václav Klaus and Miloš Zeman. Other Prime Ministers of the Czech Republic were conservative politicians, such as Mirek Topolánek, Petr Nečas, and social democratic such as Vladimír Špidla, Jiří Paroubek, Bohuslav Sobotka.

The arts

Music

Czech music had its first significant pieces created in the 11th century. The great progress of Czech artificial music began with the end of the Renaissance and the early Baroque era, concretely in works of Adam Václav Michna z Otradovic, where the specific character of Czech music was rising up by using the influence of genuine folk music. This tradition determined the development of Czech music and has remained the main sign in the works of great Czech composers of almost all eras – Jan Dismas Zelenka and Josef Mysliveček in Baroque, Bedřich Smetana and Antonín Dvořák in Romanticism, Leoš Janáček, Bohuslav Martinů and Josef Suk in modern classical or Petr Eben and Miloslav Kabeláč in contemporary classical music.

Czech musicians also played an important role in the development of European music. Jan Václav Antonín Stamic in 18th-century contributed to the creation of Classicism in music by innovations of compositional forms and the founding of the Mannheim school. Similarly, Antonín Rejcha's experiments prefigured new compositional techniques in the 19th century. The influence of Czech musicians expanded beyond the borders of the European continent, when Antonín Dvořák created a new American classical music style, using the richness of ethnic music of that country during his mission in the US. The contribution of Alois Hába to microtonal music in the 20th century must be also mentioned.

Czech music reached as far as Qing China. Karel Slavíček was a Jesuit missionary, scientist and sinologist who was introduced to the Kangxi Emperor on 3 February 1717, in Beijing. The emperor favored him and employed him as court musician. (Slavíček was a Spinet player).

Some notable modern Czech musicians are US-based composer and guitarist Ivan Král, musician and composer Jan Hammer and the rock band The Plastic People of the Universe which played an important part in the underground movement during the communist regime.

The Czech Republic first entered the Eurovision Song Contest in 2007. Czech performer qualified for the grand final for the first time in 2016 when singer Gabriela Gunčíková finished in 25th place. In 2018 the singer Mikolas Josef reached the 6th place in the contest being the best result of the Czech Republic until today.

The first Czech models have made a breakthrough in the international modeling were Paulina Porizkova or Ivana Trump. After the fall of communism in Czechoslovakia many other models succeeded: Karolína Kurková, Eva Herzigová, Taťána Kuchařová, Petra Němcová and Daniela Peštová.

Saints

Czech culture involves many saints, most notably St. Wenceslaus (Václav), patron of the Czech nation, St. John of Nepomuk (Jan Nepomucký), St. Adalbert (Vojtěch), Saint Procopius or St. Agnes of Bohemia (Anežka Česká). Although not a Christian, rabbi Judah Loew ben Bezalel of Prague, a 16th Century scholar and one of the most influential figures of Jewish history, is considered to be part of the country's religious legacy as well.

Natives

The modern Czech nation was formed through the process of the Czech national revival. Through this was created the linguistic concept of the Czech nation (particularly promoted by Jungmann), i.e. "a Czech=one who has the Czech language as their first language; naturally or by choice" (that is why Slovaks who have chosen Czech as their literary language, such as Ján Kollár or Pavel Jozef Šafařík, are often considered to be Czechs). Like other nations, Czechs also speak of two alternative concepts: the landed concept (a Czech is someone who was born in the historic Czech territory), which in Jungmann's time primarily denoted nobility, and the ethnic concept. Definition by territory is still discussed alternative, from time to time is indicated for Czechs number of natives (speaking mostly German, English or otherwise) – these include US Secretary of State Madeleine Albright, film director Karel Reisz, actor Herbert Lom, the founder of psychoanalysis Sigmund Freud, the founder of genetics Gregor Mendel, logician and mathematician Kurt Gödel, the philosopher Edmund Husserl, scientists Gerty Cori, Carl Cori and Peter Grünberg (all Nobel Prize winners) and Ernst Mach, economists Joseph Schumpeter and Eugen Böhm von Bawerk, philosophers Bernard Bolzano, Ernest Gellner, Vilém Flusser and Herbert Feigl, Marxist theoretician Karl Kautsky, astronomer Johann Palisa, legal theorist Hans Kelsen, inventors Alois Senefelder and Viktor Kaplan, automotive designer Ferdinand Porsche, psychologist Max Wertheimer, a geologist Karl von Terzaghi, musicologists Eduard Hanslick and Guido Adler, chemist Johann Josef Loschmidt, biologists Heinrich Wilhelm Schott and Georg Joseph Kamel, the founder of the dermatology Ferdinand Ritter von Hebra, peace activist Bertha von Suttner (Nobel Peace Prize), the composers Gustav Mahler, Heinrich Biber, Viktor Ullmann, Ervin Schulhoff, Pavel Haas, Erich Wolfgang Korngold and Ralph Benatzky, writers Franz Kafka, Reiner Maria Rilke, Max Brod, Karl Kraus, Franz Werfel, Marie von Ebner-Eschenbach, Leo Perutz, Tom Stoppard and Egon Erwin Kisch, painters Anton Raphael Mengs and Emil Orlik, architects Adolf Loos, Peter Parler, Josef Hoffmann, Jan Santini Aichel and Kilian Ignaz Dientzenhofer, cellist David Popper, violist Heinrich Wilhelm Ernst, pianists Alice Herz-Sommer and Rudolf Serkin, president of Austria Karl Renner, Prime Minister of Poland Jerzy Buzek, industrialist Oskar Schindler, or chess player Wilhelm Steinitz.

Geography

The Czechs live in three historical lands: Bohemia, Moravia, and Czech Silesia; these regions make up the modern Czech Republic. However, the country is now divided into 14 administrative regions. The local culture varies somewhat in each of the historical regions. Moravians are usually more nationalistic regional patriots of Moravia, but they also speak Czech. Local dialects (such as Central Bohemian, the Chod dialect, Moravian dialects, Cieszyn Silesian, etc.) are found in various parts of the country.

Czech language

The Czech language is spoken by approximately 12 million people around the world, but the vast majority are in the Czech Republic. It developed from the Proto-Slavic language in the 10th century and is mutually intelligible with the Slovak language.

Religion

In 1977, Richard Felix Staar described Czechs as "tolerant and even indifferent towards religion as a rule".

After the Bohemian Reformation, most Czechs (about 85%) became followers of Jan Hus, Petr Chelčický and other regional Protestant Reformers. Bohemian Estates' defeat in the Battle of White Mountain brought radical religious changes and started a series of intense actions taken by the Habsburgs in order to bring the Czech population back to the Roman Catholic Church. After the Habsburgs regained control of Bohemia, Czech people were forcibly converted to Roman Catholicism. All kinds of Protestant communities including the various branches of Hussites, Lutherans and Reformed were either expelled, killed, or converted to Catholicism. The Catholic Church lost the bulk of its adherents during the Communist era.

As of 2015, Pew Research Center found in that 72% of the population of Czech Republic declared to be irreligious, a category which includes atheists, agnostics and those who describe their religion as "nothing in particular", 26% were Christians (vast majority Catholics), while 2% belonged to other faiths.

Demographics

In the Czech Republic, the nation state of the Czech people, 6,732,104 (63.7%) declared as ethnic Czech according to the 2011 census. Notably, another 2,742,669 (26%) were undeclared, and 522,474 (4.9%) declared as Moravians. There is a large Czech diaspora, which includes 1,703,930 Americans of Czech/Czechoslovak ancestry, 94,805 Canadians of Czech ancestry, an estimated 45,000 Czech-born residents in the United Kingdom, and ca. 31,000 in Australia. There are smaller communities throughout Europe. Number of Israelis of Czech-Jewish ancestry is estimated to be about 50,000 to 100,000.
