Mongolia under Qing rule was the rule of the Manchu-led Qing dynasty of China over the Mongolian Plateau, including the four Outer Mongolian aimags (tribes), the six Inner Mongolian leagues, and other Mongol territories, from the 17th century to the end of the dynasty. The term "Mongolia" is used here in the broader historical sense, and includes an area much larger than the modern-day state of Mongolia. By the early 1630s Ligdan Khan saw much of his power weakened due to the disunity of the Mongol tribes. He was subsequently defeated by the Later Jin dynasty and died soon afterwards. His son Ejei handed the Yuan imperial seal over to Hong Taiji in 1635, thus ending the rule of the Northern Yuan dynasty in Inner Mongolia. However, the Khalkha Mongols in Outer Mongolia continued to rule until they were overrun by the Dzungar Khanate in 1690, and they submitted to the Qing dynasty in 1691.

The Qing dynasty ruled Inner and Outer Mongolia for over 200 years. During this period, Qing rulers established separate administrative structures to govern each region. While the empire maintained firm control in both Inner and Outer Mongolia, the Mongols in Outer Mongolia (which is further from the capital Beijing) enjoyed a higher degree of autonomy,The Cambridge History of China, vol10, pg49 and also retained their own language and culture during this period.Paula L. W. Sabloff- Modern mongolia: reclaiming Genghis Khan, p. 32.

Some scholars point out the Qing Empire's multiethnic makeup as support for the argument that Mongolia was not ruled by a Chinese state since the Qing was ruled by Manchus instead of Han Chinese. Education in Mongolia portrays the period of Qing rule as the period of Manchu rule. Other scholars point out that the Qing dynasty considered itself to be the Middle Kingdom or Zhongguo, translated as "China", regardless of ethnicity and even expanded on the definition of "Chinese" to include its multi-ethnic population, including the Manchus and Mongols.

History

The Khorchin Mongols allied with Nurhaci and the Jurchens in 1626, submitting to his rule for protection against the Khalkha Mongols and Chahar Mongols. 7 Khorchin nobles died at the hands of Khalkha and Chahars in 1625. This started the Khorchin alliance with the Qing.

During the course of the 17th and 18th centuries, most regions inhabited by ethnic Mongols, notably Outer and Inner Mongolia became part of the Qing Empire. Even before the dynasty began to take control of China proper in 1644, the escapades of Ligden Khan had driven a number of Mongol tribes to ally with the Later Jin. The Later Jin conquered a Mongol tribe in the process of war against the Ming. Nurhaci's early relations with the Mongols tribes was mainly an alliance.Marriage and inequality in Chinese society By Rubie Sharon Watson, Patricia Buckley Ebrey, p.177Tumen jalafun jecen akū: Manchu studies in honour of Giovanni Stary By Giovanni Stary, Alessandra Pozzi, Juha Antero Janhunen, Michael Weiers After Ligden's defeat and death his son had to submit to the Later Jin, and when the Qing dynasty was founded the following year, most of what is now called Inner Mongolia already belonged to the new state. The Khalkha Mongols in Outer Mongolia joined in 1691 when their defeat by the Dzungars left them without a chance to remain independent. The Khoshud in Qinghai were conquered in 1723/24. The Dzungars were finally destroyed, and their territory conquered, in 1756/57 during the Dzungar genocide. The last Mongols to join the empire were the returning Torgud Kalmyks at the Ili in 1771.

After conquering the Ming, the Qing identified their state as Zhongguo (中國, the term for "China" in modern Chinese), and referred to it as "Dulimbai Gurun" in the Manchu language. When the Qing conquered Dzungaria in 1759, they proclaimed that the new land which formerly belonged to the Dzungar Mongols was now absorbed into "China" (Dulimbai Gurun) in a Manchu language memorial.Dunnell 2004, p. 77.Dunnell 2004, p. 83.Elliott 2001, p. 503. The Qing expounded on their ideology that they were bringing together the "outer" non-Han peoples like the Inner Mongols, Eastern Mongols, Oirat Mongols, and Tibetans together with the "inner" Han people, into "one family" united in the Qing state.Dunnell 2004, pp. 76-77. The Manchu language version of the Convention of Kyakhta (1768), a treaty with the Russian Empire concerning criminal jurisdiction over bandits, referred to people from the Qing as "people from the Central Kingdom (Dulimbai Gurun)",Cassel 2011, p. 205.Cassel 2012, p. 205.Cassel 2011, p. 44.Cassel 2012, p. 44. and the usage of "Chinese" (Dulimbai gurun i niyalma) in the convention certainly referred to the Mongols.Zhao 2006, pp. 14. In the Manchu official Tulisen's Manchu language account of his meeting with the Torghut Mongol leader Ayuki Khan, it was mentioned that the Torghut Mongols were unlike the Russians but were instead like the "people of the Central Kingdom" (中國之人; Dulimbai gurun i niyalma) such as the Manchus.Perdue 2009, p. 218.

From the early years, the Manchus' relations with the neighboring Mongol tribes had been crucial in the dynasty development. Nurhaci had exchanged wives and concubines with the Khalkha Mongols since 1594, and also received titles from them in the early 17th century. He also consolidated his relationship with portions of the Khorchin and Kharachin populations of eastern Mongols. They recognized Nurhaci as Khan, and in return leading lineages of those groups were titled by Nurhaci and married with his extended family. Nurhaci chose to variously emphasize either differences or similarities in lifestyles with the Mongols for political reasons.Perdue 2009, p. 127. Nurhaci said to the Mongols that "The languages of the Han and Koreans are different, but their clothing and way of life is the same. It is the same with us Manchus (Jušen) and Mongols. Our languages are different, but our clothing and way of life is the same." Later Nurhaci indicated that the bond with the Mongols was not based in any real shared culture, rather it was for pragmatic reasons of "mutual opportunism", when he said to the Mongols: "You Mongols raise livestock, eat meat and wear pelts. My people till the fields and live on grain. We two are not one country and we have different languages."Peterson 2002, p. 31. As Nurhaci formally declared independence from the Ming dynasty and proclaimed the Later Jin in 1616, he gave himself a Mongolian-style title, consolidating his claim to the Mongolian traditions of leadership. The banners and other Manchu institutions are examples of productive hybridity, combining "pure" Mongolian elements (such as the script) and Han Chinese elements. Intermarriage with Mongolian noble families had significantly cemented the alliance between the two peoples. Hong Taiji further expanded the marriage alliance policy; he used the marriage ties to draw in more of the twenty-one Inner Mongolian tribes that joined the alliance with the Manchus. Despite the growing intimacy of Manchu-Mongol ties, Ligdan Khan, the last Khan from the Chakhar, resolutely opposed the growing Manchu power and viewed himself as the legitimate representative of the Mongolian imperial tradition. But after his repeated losses in battle to the Manchus in the 1620s and early 1630s, as well as his own death in 1634, his son Ejei Khan eventually submitted to Hong Taiji in 1635 and the Yuan seal is also said to be handed in to latter, ending the Northern Yuan. Ejei Khan was given the title of Prince (Qin Wang, 親王). The surrendered Inner Mongols were divided into separate administrative banners. Soon afterwards the Manchus founded the Qing dynasty and became the ruler of China proper.

Ejei Khan died in 1661 and was succeeded by his brother Abunai. After Abunai showed disaffection with Manchu Qing rule, he was placed under house arrested in 1669 in Shenyang and the Kangxi Emperor gave his title to his son Borni. Abunai then bid his time and then he and his brother Lubuzung revolted against the Qing in 1675 during the Revolt of the Three Feudatories, with 3,000 Chahar Mongol followers joining in on the revolt. The Qing then crushed the rebels in a battle on April 20, 1675, killing Abunai and all his followers. Their title was abolished, all Chahar Mongol royal males were executed even if they were born to Manchu Qing princesses, and all Chahar Mongol royal females were sold into slavery except the Manchu Qing princesses. The Chahar Mongols were then reorganized into the Eight Banners of Chahar under the direct control of the Qing Emperor unlike the other Inner Mongol leagues which maintained their autonomy.

The Khalkha Mongols were more reluctant to come under Qing rule, only submitting to the Kangxi Emperor after they came under an invasion from the Oirat Mongol Dzungar Khanate under its leader Galdan.

The three khans of Khalkha in Outer Mongolia had established close ties with the Qing dynasty since the reign of Hong Taiji, but had remained effectively self-governing. While Qing rulers had attempted to achieve control over this region, the Oyirods to the west of Khalkha under the leadership of Galdan were also actively making such attempts. After the end of the war against the Three Feudatories, the Kangxi Emperor was able to turn his attentions to this problem and tried diplomatic negotiations. But Galdan ended up with attacking the Khalkha lands, and Kangxi's responded by personally leading Eight Banner contingents with heavy guns into the field against Galdan's forces, eventually defeating the latter. In the meantime Kangxi organized a congress of the rulers of Khalkha and Inner Mongolia in Duolun in 1691, at which the Khalkha khans formally declared allegiance to him. The war against Galdan essentially brought the Khalkhas to the empire, and the three khans of the Khalkha were formally inducted into the inner circles of the Qing aristocracy by 1694. Thus, by the end of the 17th century the Qing dynasty had put both Inner and Outer Mongolia under its control.

The Oirat Khoshut Upper Mongols in Qinghai rebelled against the Qing during the reign of the Yongzheng Emperor but were crushed and defeated.

Khalkha Mongol rebels under Prince Chingünjav had plotted with the Dzungar leader Amursana and led a rebellion against the Qing at the same time as the Dzungars. The Qing crushed the rebellion and executed Chingünjav and his entire family.

Once brought under Qing control, the traditional clan structures of Inner and Outer Mongolia were replaced with the Manchu Banner system.Black 1991, p. 47. This new administrative structure had drastic consequences for Mongolian culture, as the leader (Jasagh) of each banner was chosen by Qing authorities, although existing Mongol princes were often picked for the position. Rawski 1998, p. 67. This had the impact of weakening relations between different Mongol clans, while also increasing ties between Mongol culture and the Qing court. Additionally, the Banner structure heightened the influence of Chinese culture over the Mongol clans, especially within Inner Mongolia, where Mongol princes used Chinese architecture to build their palaces.

Furthermore, Mongols were forbidden by the Qing from crossing the borders of their banners, even into other Mongol Banners, and from crossing into neidi (the Han Chinese 18 provinces). Doing so would result in serious punishment, thereby keeping the Mongol clans isolated and disconnected, preventing the formation of united Khanate and maintaining Qing control in these regions.Bulag 2012, p. 41. Mongol pilgrims wanting to leave their banner's borders for religious reasons such as pilgrimage had to apply for passports to give them permission.
