Korchak culture
The Korchak culture is an archaeological culture of the sixth and seventh century East Slavs who settled along the southern tributaries of the Pripyat River and from the Dnieper River to the Southern Bug and Dniester rivers, throughout modern-day northwestern Ukraine and southern Belarus. It forms the eastern part of the so-called Prague-Korchak cultural horizon, a term used to encompass the   entirety of postulated early Slavic cultures from the Elbe to the Dniester, as opposed to the eastern Penkovka culture.
