The influence of the Iranian culture on Eastern Europe is undisputable. Scholars write of the Southern-Iranian road which stretched from the south, from the Parthians, Persia, and the Transcaucasia, to the north Iranian way through Khwarezm and as far as the Volga. The extent of the Iranian influence on the tribes populating southern Siberia prior to the Common Era however, is much less clear. It is believed that the Savirs/Suvars were the ancestors of the Chuvash. Although this theory has not yet been proven fully, it has served as a theme for historical and philological research. Drawing on geographic, religious, and linguistic materials this study attempts to trace the relationship between Iranian tribes and the Savir ancestors of the Chuvash.
