The article discusses the cultural situation within a broadly understood borderland of Western and Eastern Europe spanning the interfluve of the Vistula and the Dnieper. The period selected for the study, i.e. the 3rd millennium B.C. was characterized, in the light of current knowledge, by varied forms of cultural contacts that brought together the societies of the Western and Eastern European cultural realm. The socio-cultural transformations that took place in those times resulted at the end of the 3rd millennium B.C. in a new landscape of this cultural borderland.
