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.
