東スラヴ人
Early East Slavs settled the forested hills of today's Minsk by the 9th century. They had been migrating from further south and pushing the preceding Balts northwards. The valley of "Svislach" river was settlement boundary between two Early East Slavs' tribal unions – Krivichs and Dregovichs. By 980 the area was incorporated into the early medieval Principality of Polatsk, one of the earliest East Slav states along with the principalities of Kiev and Novgorod.
