context_page_description: The Czechs, or the Czech people, are a West Slavic ethnic group and a nation native to the Czech Republic in Central Europe, who share a common ancestry, culture, history, and Czech language.
  Ethnic Czechs were called Bohemians in English until the early 20th century, referring to the medieval land of Bohemia which in turn was adapted from late Iron Age tribe of Celtic Boii. During the Migration Period, West Slavic tribes of Bohemians settled in the area, "assimilated the remaining Celtic and Germanic populations", and formed a principality in the 9th century, which was part of Great Moravia, in form of 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, Canada, Israel, Austria, Germany, Slovakia, Switzerland, Italy, the United Kingdom, Australia, Chile, Russia, Argentina and Brazil, among others.
context_section_description: 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. According to a 2007 study, 34.2% of Czech men belong to R1a. Within the Czech Republic, the proportion of R1a seems to gradually increase from west to east  According to a 2000 study, 35.6% of Czech men have haplogroup R1b, which is very common in Western Europe among Germanic and Celtic nations, but rare among Slavic nations. 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. A group of scientists suggested that the high frequency of a gene mutation causing cystic fibrosis in Central European (including Czech R.) and Celtic populations supports the theory of some Celtic ancestry among the Czech population.
