Pan-Mongolism is an irredentist idea that advocates cultural and political solidarity of Mongols. The proposed territory, called "Greater Mongolia" (Mongolian: Даяар Монгол, Dayaar Mongol), usually includes the independent state of Mongolia, the Chinese regions of Inner Mongolia and Dzungaria (in Xinjiang), and the Russian subjects of Buryatia. Sometimes Tuva, and the Altai Republic and parts of Zabaykalsky Krai and Irkutsk Oblast are included as well. As of 2006[update], all areas in Greater Mongolia except Mongolia have non-Mongol majorities.
The nationalist movement emerged in the 20th century in response to the collapse of the Qing dynasty and the possibility of an independent Mongolian state. After the Red Army helped to establish a Mongolian People's Republic, Mongolian foreign policy prioritized seeking recognition of independence over territorial expansion. After the 1990 Mongolian Revolution ended Communist rule in Mongolia, a number of organizations have emerged that promote pan-Mongolism, but they have little popular support.
The Qing dynasty (1644–1912) controlled modern-day Mongolia, Tuva, Western Mongolia, and Inner Mongolia. However, before the People's Republic of China (1949–present) greatly expanded the territory of Inner Mongolia to its present shape, Inner Mongolia only referred to the Mongol areas within the Chinese provinces of Ningxia, Suiyuan, and Chahar. The Mongols in Manchuria, known then as Xing'an but now as Hulunbuir, were considered to be ethnically distinct from both the Inner and Outer Mongol tribes, and this region was called "Eastern Mongolia". Inner Mongolia, which had joined the Qing in 1636 as allies rather than conquered subjects, were directly administered and taxed by the Qing, and given access to the Qing aristocracy.Outer Mongolia was given more autonomy, nomadic rights, and its own Buddhist center. Having colonized Buryatia in the 17th century, and the Amur Basin in 1862, the Imperial Russian government pursued policies in support of a "long-range expansionist policy intended to one day strip control of Mongolia away from China".
