But how did it spread from there to Asia? The aim of this thesis is to uncover the early prehistory of Indo-Iranian by investigating its relationship to the Balto-Slavic languages of Eastern Europe, which have been hypothesized to form a subgroup with Indo-Iranian: Indo-Slavic. By comparing the linguistic data with evidence from archaeology and genetics, this thesis traces the migration path of prehistoric Indo-Iranian speakers from the Pontic-Caspian steppe, via the rivers and forests of Eastern Europe, across the Ural Mountains, and southwards to the steppes of Central Asia.
