The Barga (Mongol: Барга; ) are a subgroup of the Buryats which gave its name to the Baikal region – "Bargujin-Tukum" (Bargujin Tökhöm) – "the land's end", according to the 13th-14th centuries Mongol people's conception. History In the 7–8th centuries, ancestors of Bargas, the Bayirku, a Turkic tribe appeared as tribes near Lake Baikal, named Bargujin. In "Old Tangs Book", it was called "拔野古", "拔野固", "拔曳固". Genghis Khan's ancestor Alan Gua was of Barga ancestry. In the Mongol Empire, they served the Great Khans' armies. One of them named Ambaghai commanded the artillery. Manlaibaatar Damdinsüren and Khorloogiin Choibalsan were the famous military commander from Barga in the early 20th century. Xianbei Period The Barga supported the XianBei invasion of China and provided 8,000 horse cavalry. Second Turkic khaganate Period The Barga (Bayegu) had revolted in 707. These revolts continued until 716 and Qapaghan Qaghan, on his way back from suppressing revolts by the Uyghur, Tongluo, Baixi, Barga (Bayegu) and Pugu, was ambushed and killed by a Barga tribesman named Sijelu on 716 July 22. 14th to 17th centuries After the fall of the Yuan dynasty in 1368, the Barga joined the Oirats against the Genghisids. However, they were scattered among the Mongols and Oirats. The Barga share the same 11 clans into which the Khori-Buryats were divided. The main body of Khori-Barga moved to the area between Ergune river and the Greater Khingan Range where they became subject to the Daurs and Solon Ewenkis. A large body of Barga Khoris fled back east to the Onon river in 1594. While some came under Russian rule, others became tributary to the Khalkha. Qing dynasty Period When the Qing dynasty attacked the Cossacks in the Ergune and Shilka rivers in 1685–89, those Barga Mongols east of the Ergune River were deported to Manchuria. The Qing court dispersed them among the Chahar banners. They predominantly live Hulunbuir since the 17th century. In 1900~1901 Russia-Manchuria Railway conflict, Manchurian commander QuanFu led local defensive force and fought against Russian soldiers at Ongon railway station and Hargantu railway stations. 800 Barga/Solon native soldiers were killed in the event.
