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 border 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. Traditionally, they formed the major northern subgroup of the Mongols.
