The Mongols are an East Asian ethnic group native to Mongolia, China, as well as Buryatia and Kalmykia of Russia. The Mongols are the principal member of the large family of Mongolic peoples. The Oirats in Western Mongolia as well as the Buryats and Kalmyks of Russia are classified either as distinct ethno-linguistic groups or subgroups of Mongols.

The Buryats are a Mongolic ethnic group native to southeastern Siberia who speak the Buryat language. They are one of the two largest indigenous groups in Siberia, the other being the Yakuts. The majority of the Buryats today live in their titular homeland, the Republic of Buryatia, a federal subject of Russia which sprawls along the southern coast and partially straddles Lake Baikal. Smaller groups of Buryats also inhabit Ust-Orda Buryat Okrug and the Agin-Buryat Okrug which are to the west and east of Buryatia respectively as well as northeastern Mongolia and Inner Mongolia, China. They traditionally formed the major northern subgroup of the Mongols.
