Урянхайский край
There are few written sources for the history of Tannu Uriankhai prior to the mid-18th century. Moreover, these sources often do not distinguish between the Tannu Uriankhai, the Altai Uriankhai, and the Altainor Uriankhai. In general, the land has played only a passive role in the history of Inner Asia, passing without much difficulty from one conqueror to another. It was dominated by a series of Turkic khanates of northern Mongolia; Turks, Uighurs and Kirghiz although, it appears that the real Turkification of the region began with the flight of Turkic tribes into this area after the rise of Genghis Khan in the 13th century.
