It comes from the name of the West Slavic ethnic group originating from the Czech lands - the Czechs, who settled in these areas in the 6th or 7th century. It means the westernmost and largest historical region of the Czech lands and the modern Czech Republic.
The Latin, medieval name of the Czech Republic - Bohemia (Boiohaemum) comes from the Boii, a Celtic tribe inhabiting this area before the arrival of the early Slavs. Bohemus - a resident of the Czech Republic, was later used to describe Gypsies who, as it was believed, came from the Czech Republic
