During the following millennium the representatives of the Kurgan Culture made their way into central Europe, the Balkan Peninsula, Transcaucasia, Anatolia, and northern Iran (ca. 3500–3000 B.C.); in the third millennium they reached northern Europe, the Aegean zone (Greece and the coasts of Anatolia), and the eastern Mediterranean. According to Marija Gimbutas, the peoples who developed and disseminated the Kurgan Culture can only have been the Proto-Indo-Europeans and, in the last phases of their dispersal, the Indo-Europeans.
