In the 7–8th centuries, ancestors of Bargas, the Bayirku, a tribe of
Tiele confederation appeared as tribes near
Lake Baikal, named Bargujin. The
Old Book of Tang recorded various names, including "拔野古", "拔野固", and "拔曳固". With regard to the Bayirku, alongside the
Turkic version there are also hypotheses suggesting that they represented
Mongolic elements within the Tiele confederation. The hypothesis of the Turkic origin of the Bayirku is shared by a number of researchers, such as N. A. Aristov, É. Chavannes, A. N. Bernshtam, B. R. Zoriktuev. The version of the Ancient Mongolic origin of the Bayegu/Bayïrku was first put forward in detail by G. N. Rumyantsev. The Mongolic hypothesis of the origin of the Bayegu/Bayïrku was supported by scholars Ts. B. Tsydendambaev, A. Ochir, P. B. Konovalov, S. B. Miyagasheva, G. Tubshinima. 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 famous military commanders 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 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 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 in
Hulunbuir since the 17th century. In 1900~1901 Russia-Manchuria Railway conflict, Manchurian commander Quan Fu 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.
Relocation - Old Barga ("Huuchin Barga" in Mongolian) After the
Treaty of Nerchinsk, Qing dynasty decided to increase the defensive line of
Hulunbuir against Russian influence. In 1732, under the command of Qing commander Tabhan and Bulbantsa, total 3000 (1636 Solon soldiers, 730 Dagur soldiers, 275 Barga soldiers and 359 Orqon soldiers) were selected and stationed in Hulunbuir mostly from non Muren area. After 2000 soldiers were forced to join
Dzungar-Qing wars in 1733, mostly Barga soldiers were left to protect this area. They became "Old Barga", since they arrived before New Barga.
Relocation - New Barga ("Shine Barga" in Mongolian) In order to support
Dzungar–Qing Wars, 2000 Solon Barga soldiers were selected by
Qing commander Jorhai in 1733 to fight against Dzungar and local defence was left with merely 1,100 soldiers. Thus it became extremely important to increase local defense against Russian
Cossack. In 1734, the Barga Mongols who had been left under the Khalkha
noyans complained of the mistreatment of their lords and the Qing authority selected 2,984 Barga Mongolian soldiers in Khalkha and stationed them with their families in
Khölönbuir, Dornod. They became "New Barga", since they arrived after Old Barga.
Military Support to Qing dynasty In 1733, 2000 soldiers (mostly Solon Barga soldiers from the forest tribes) were forced to join
Dzungar-Qing Wars. They never returned. In 1755, 3000 Barga soldiers were forced to join
Dzungar-Qing Wars. They never returned. In 1758, 3000 Barga teenagers were forced to join
Dzungar-Qing Wars, since there were not enough adults. They never returned. In 1840, some Barga soldiers (numbers unknown) joined
First Opium War, and some of them returned home in 1841. In other occasions, 750~50 Barga soldiers were selected to support
Qing dynasty campaigns for around 20 times. In 1901, 800 local Barga soldiers were killed in
Chinese Eastern Railway construction.
Japanese occupation period In 1939, local Barga people were forced to join the
Soviet–Japanese border conflicts. The unclear border definition between New Barga Left Banner and
Dornod (where Barga originally lived) was the major excuse for the start of
Battles of Khalkhin Gol.
