BayadsThe Bayad (Mongol: Баяд/Bayad, lit. "the Riches") is the third largest subgroup of Mongol people in modern Mongolia and they are a tribe in Four Oirats. Baya'ud were a prominent clan within the Mongol Empire. Baya'ud can be found in both Mongolic and Turkic peoples. Within Mongols, the clan is spread through Khalkha, Inner Mongolians, Buryats and Oirats. The clan name Baya'ud appears among the Mongols, while the ethnonym Bayid appears in Central Siberia. Only the latter appears to be connected to the modern Bayad people of western Mongolia.
Khalkha MongolsThe Khalkha or Kalka (Halh, Mongolian script: ˈχɑɮχ, Kè-ěr-kè) have been the largest subgroup of Mongol people in modern Mongolia since the 15th century. The Khalkha, together with Chahars, Ordos and Tumed, were directly ruled by Borjigin khans until the 20th century; unlike the Oirats, who were ruled by Dzungar nobles or the Khorchins, who were ruled by Qasar's descendants. The two original major Khalkha groups were ruled by the direct male line descendants of Dayan Khan.
BuryatsThe Buryats (Buryaad, ᠪᠣᠷᠢᠶᠠᠳ; Buriad) 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.
KalmykiaKalmykia, officially the Republic of Kalmykia, is a republic of Russia, located in the North Caucasus region of Southern Russia. The republic is part of the Southern Federal District, and borders Dagestan to the south and Stavropol Krai to the southwest; Volgograd Oblast to the northwest and north and Astrakhan Oblast to the north and east; Rostov Oblast to the west and the Caspian Sea to the east. Kalmykia is the only region in Europe where Buddhism is the predominant religion.
KalmyksThe Kalmyks (Kalmyk: Хальмгуд, Xaľmgud; Halimaguud; Калмыки; archaically anglicised as Calmucks) are a Mongolic ethnic group living mainly in Russia, whose ancestors migrated from Dzungaria. They created the Kalmyk Khanate from 1635 to 1779 in the south of the European part of Russia territory. Today they form a majority in Kalmykia, located in the Kalmyk Steppe, on the western shore of the Caspian Sea. They are the only traditionally Buddhist people who are located within Europe.
