Slavs 6th century
By the C6 the Slavs were the largest European race. Their early origin is not known, but from 1AD they were thought to have lived in the marshes east of Russia.
Following the dissolution of the Hun Empire the Slavs made a rapid expansion populating modern Russia, Poland, Czech Republic, Slovakia, Croatia, Serbia, Macedonia, Bulgaria, and Romania. Little remains of Slavic Romania apart from some place names and possibly the voivode, administrative regions, of the Romanians inherited by the Magyars in Transylvania.
