The territory of the Mongol empire included four uluses: the Jochi Ulus (Golden Horde), the Chagatai ulus, the Hulagund State and the Yuan Empire. The empire began to form in the early 13th century, when the mongols subjugated the yenisei kyrgyz and other peoples of Southern Siberia and Eastern Kazakhstan. Then the tangut kingdom and China were conquered, and the territories of Southern Siberia, Kazakhstan, and Central Asia were captured. Then the Mongols moved to Afghanistan, India, Iran, invaded the Caucasus and the steppes of southern Eastern Europe.
The Jochi Ulus was one of the largest in the empire, occupying vast areas of Siberia, the Urals, the Volga region, the Black Sea region, the Caspian region, Central Asia, and the Caucasus. The documents of the XIII–XV centuries mention ethnic and tribal formations that lived here: alshyns, argyns, baryns, bashkurts, derbets, dulats, katagans, karakitai, kipchaks, konyrats, kangly, keneges, kerei, kereites, kiyat, mazhar, mangyts, naimans, seyids, oirats, uak, uysuni, uygurs, widths.
During the mongol invasion of the 13th century, the bashkir tribes of the Southern Urals, like most of their neighbors, recognized their dependence on the Mongol empire. Some did it voluntarily, forcibly, while others did it under direct military pressure.
