The Mongolian Revolution of 1921, locally known as the People's Revolution of 1921, was a military and political event by which Mongolian revolutionaries, with the assistance of the Soviet Red Army, expelled Russian White Guards from the country, and founded the Mongolian People's Republic in 1924. Although nominally independent, the Mongolian People's Republic was a satellite state of the Soviet Union until the democratic revolution in January 1990. The revolution also ended the Chinese Beiyang government's occupation of Mongolia, which had begun in 1919.

Prelude

National Liberation Revolution of 1911

For about three centuries, the Qing dynasty had enforced—albeit with mixed success—a policy of segregating the non-Han peoples on the frontier from the Han people. By the end of the 19th century, however, China faced the prospect of being parcelled out among the Western powers and Japan, each competing for its own sphere of influence in the country. On the northern frontier, the Russian Empire was viewed by the Qing court as posing the greatest threat to its territorial integrity. In response, the Qing government adopted a different policy, the "New Administration" or "New Policies" (), which called for the sinification of Mongolia through Han colonisation, the exploitation of Mongolia's natural resources (mining, timber, fishing), military training, and education.Thomas E. Ewing, Ch'ing Policies in Outer Mongolia 1900–1911, Modern Asian Studies (Cambridge, Eng., 1980), pp. 145–157.

Many Mongols regarded the "New Policies" as a major threat to their traditional way of life, as was agreed to be preserved when they recognised authority of the Qing emperors, and began to seek independence. In July 1911, a group of Khalkha nobles persuaded the Jebtsundamba Khutuktu, the head of Mongolian Buddhism, that Mongolia must declare its independence from the Qing dynasty. They agreed to send a small delegation to Russia to obtain its assistance in this undertaking.

In October 1911, the Xinhai Revolution broke out, with one province after another declaring its independence from the Qing government. On 1 December 1911, Outer Mongolia declared independence, and established a theocracy under the Khutuktu. On 29 December, he was installed as the Bogd Khan (Great Khan, or Emperor) of Mongolia.See Thomas E. Ewing, "Revolution on the Chinese Frontier: Outer Mongolia in 1911", Journal of Asian History (Bloomington, Indiana, 1978), pp. 101–19. This ushered in the Bogd Khan era, which lasted from 1911 to 1919.

Bogd Khanate

The new Mongolian government was a fusion of Buddhist theocracy, Qing imperial usages, and 20th century Western political practices. The Bogd Khan assumed the same powers—symbolic and real—of Qing emperors in the past. He adopted a reign title, "Elevated by the Many"; the Mongolian nobility now owed their tribute to him instead of to the Qing emperor; and the Bogd Khan assumed the right of conferring upon the lay nobles their ranks and seals of office. This new state also reflected the Mongols' desire to reshape their country into a modern state—they formed a national parliament composed of two chambers, a government with five ministries, and a national army.

The Buddhist religious establishment discovered new opportunities for political gain and financial profit. Despite the presence of a state government, real power lay in the Bogd Khan's court. The religious establishment appropriated revenues for its own purposes. For example, it enlarged its financial holdings by transferring to the religious estate (Ikh shav''') wealthy herdsmen who traditionally had owed their services and taxes to lay princes. There is a commonly held misconception that, over time, the greed of the Buddhist religious establishment so disaffected the lay nobility that it came to reject the very principles of theocracy upon which the new country had been founded.Thomas E. Ewing, Between the Hammer and the Anvil. Chinese and Russian Policies in Outer Mongolia, 1911–1921, (Bloomington, Indiana, 1980), pp. 34–43. According to Mongolian and Russian sources, the Mongolian society was generally satisfied with the theocracy but there were different views on future development of the country.Kuzmin, S.L. 2011. The History of Baron Ungern. An Experience of Reconstruction. Moscow: KMK Sci. Press,

On the diplomatic front, the Mongols worked tirelessly between 1912 and 1915 to win international recognition of a new pan-Mongolian state that would include Inner Mongolia, Western Mongolia, Upper Mongolia, Barga, and Tannu Uriankhai. The Republic of China, for its part, did all it could to re-establish Chinese sovereignty over the country. Russia refused to support full independence for Mongolia; nor would it agree to the restoration of Chinese sovereignty. The matter was settled in 1915 by the tripartite Treaty of Kyakhta (1915), which provided for Mongolian autonomy within the Chinese state and forbade China from sending troops to Mongolia. Both the Chinese and Mongols found the treaty equally dissatisfying, although for different reasons.

Abolition of autonomy

The outbreak of the Russian Revolution in 1917 and the Russian Civil War a year later changed the Mongolian-Chinese dynamic. In response to rumors of an imminent Bolshevik invasion, the Mongolians, very reluctantly and only after much encouragement by the Chinese High Commissioner Chen Yi at Urga (modern Ulaanbaatar), requested in the summer of 1918 military assistance from China (approximately 200 to 250 troops arrived in September). The invasion in fact did not occur, and so the Bogd Khan's government requested that the troops be recalled. The Beijing government refused, seeing this violation of the Kyakhta Treaty as the first step in restoring Chinese sovereignty over Mongolia.Ewing, Between the Hammer and the Anvil, p. 113.

Early in 1919, Grigori Semyonov, a White Guard general, had assembled a group of Buryats and Inner Mongols in Siberia for the formation of a pan-Mongolian state. The Khalkhas were invited to join, but they refused. Semyonov threatened an invasion to force them to participate. This threat galvanized the lay princes, who now saw a larger opportunity: the end of theocratic rule. In August, the Mongolian Foreign Minister approached Chen Yi with a message from the "representatives of the four aimags" (i.e., the Khalkhas) with a request for military assistance against Semyonov. More importantly, perhaps, it contained a declaration that the Khalkhas were unanimous in their desire to abolish autonomy and restore the previous Qing system. Negotiations, with participation of the Bogd Khan's representatives, began immediately. By October, Chen Yi and the Mongolian princes had agreed upon a set of conditions, the "Sixty-four Points", effectively recreating the political and administrative system. The "Points" were submitted to the Parliament. The upper house consented to it; the lower house did not.Ts. Puntsagnorov, Mongolyn avtonomit üyeiin tüükh [The history of Mongolian in the autonomous period], (Ulaanbaatar, 1955), p. 195. However, in this as in all other matters submitted to the Parliament in the past, the upper house prevailed. Chen Yi sent the draft Articles to Beijing. The Bogd Khan dispatched a delegation of lamas to Beijing with a letter stating that the people of Mongolia did not want to abolish autonomy. He wrote that this was all a contrivance of Chen Yi, and he asked that Chen be recalled.Zhung-O guanxi shiliao: Wai Menggu [Sources on Chinese-Russian relations: Outer Mongolia], (Taipei, 1959), no. 386, pp. 573–574. However, the Chinese government was not interested in esoteric arguments on whether or not a consensus existed in Mongolia for the abolition of autonomy. The "Points" were submitted to the Chinese National Assembly, which approved them on October 28.Zhung-O, app. 1, pp. 28–29. Political events then unfolding in China were to fundamentally alter Mongolian history. The Beijing government was controlled by a group of warlords nicknamed the "Anhui clique" headed by Duan Qirui. The government had come under severe public criticism for its failure at the Paris Peace Conference to obtain a just settlement of the Shandong Problem. There was criticism also of Duan's "War-participation army", which ostensibly had been formed for service in Europe in the First World War but in fact was used to maintain Duan's internal control. To divert criticism, he simply rechristened his office the "Bureau of Frontier Defense" and his army the "Frontier Defense Army". In June 1919, Xu Shuzheng, a prominent member of Duan's clique, was named "Northwest Frontier Commissioner", making him the senior Chinese military and civilian officer of Outer Mongolia.Li Yushu, Waimeng zhengjiao chidu kao [Study of the Outer Mongolian political system], (Taipei, 1962), p. 237.

Earlier, in April, Xu had submitted a plan to the Beijing government for the total social and economic reconstruction of Mongolia, proposing, among other things, that Chinese colonisation and intermarriage between Chinese and Mongolians be encouraged in order to "transform the customs of the Mongols".Zhung-O, no. 108, pp. 380–384. In short, Xu appeared to want nothing less than the total sinification of Mongolia under his authority.

Chen Yi's Sixty-four Points, which guaranteed Mongolia a kind of autonomy, would have compelled Xu to abandon his plans. This may explain the timing of his personal intervention. Xu arrived in Urga in October accompanied by a military contingent. He informed Chen that the Sixty-four Points would have to be renegotiated based upon a new set of proposals, his "Eight Articles", which called for an increase in population (presumably through Chinese colonisation) and economic development. Xu presented the Articles to the Bogd Khan with a threat that refusal to ratify them would result in his deportation. The Bogd Khan submitted the Articles to the Mongolian Parliament. As before, the upper house accepted them, while the lower house did not; some members of the lower house even threatened to expel Xu by force. Lamas resisted Xu's plans most of all. But again, the upper house prevailed.L Dendev, Mongolyn tovch tüükh [A short history of Mongolia], (Ulaanbaatar, 1934), pp. 175–176. On 17 November 1919, Xu accepted a petition—signed by the ministers and deputy ministers but not by the Bogd Khan himself—for the abolition of autonomy.Zhung-O, no. 414, p. 589.

Xu returned to Beijing, where he received a hero's welcome arranged by the Anhui clique. By December, he was back in Urga to organise a formal ceremony for the transfer of authority: soldiers were lined up on either side of the road to the Bogd Khan's palace; the portrait of the President of China was borne on a palanquin; the flag of the Chinese republic followed, and after it a marching band. Mongols were required to prostrate themselves repeatedly before these symbols of Chinese sovereignty.Chen Chungzu, Wai menggu jinshi shi [A modern history of Mongolia], (Shanghai, 1926), bien 3, p. 11. That night, some Mongolian herdsmen and lamas gathered outside the palace and tore down the flags of the Chinese Republic hanging from the gate.A. Kallinikov, U istokov mongol'skoi revolyutsii [Sources of the Mongolian revolution], Khozyaistvo Mongolii, pt. 1, p. 74.

Resistance

Between 1919 and early 1920 a few Mongolians came to form what were known later as the "Consular Hill" (Konsulyn denj) and East Urga (Züün khüree'') groups.Thomas E. Ewing chronicled the history of these two groups in "The Origin of the Mongolian People's Revolutionary Party: 1920", Mongolian Studies (Bloomington, Ind., 1978–79), pp. 79–105. This was the beginning of resistance to Xu and the abolition of autonomy.
