The ancestors of modern Evenki groups inhabited areas adjacent to the Sayan Mountains, and it is highly likely that they took part in the process of reindeer domestication along with the Samoyedic population." The local indigenous groups that have retained their traditional lifestyle nowadays live almost exclusively in the area of the Eastern Sayan mountains. However, the local reindeer herding communities were greatly affected by russification and sovietization, with many Evenks losing their traditional lifestyle and groups like the Mator and Kamas peoples being assimilated altogether.
