The Dnieper Balts were a subgroup of the Eastern Balts, that lived in the Dnieper river basin for millennia until the Late Middle Ages, when they were partly destroyed and partly assimilated by the Slavs by the 13th century.[1] To the north and northeast of the Dnieper Balts were the Volga Finns, and to the southeast and south were the ancient Iranians, the Scythians.[1]
