Inner Mongolia, officially the Inner Mongolia Autonomous Region (IMAR), is an autonomous region of China. Its border includes two-thirds of the length of China's border with the country of Mongolia, as well as a small section with Russia (Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao and Ordos.

The autonomous region was established in 1947, incorporating the areas of the former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei, and Xing'an, along with the northern parts of Gansu and Ningxia.

Its area makes it the third largest Chinese administrative subdivision, constituting approximately and 12% of China's total land area. Due to its long span from east to west, Inner Mongolia is geographically divided into eastern and western divisions. The eastern division is often included in Northeastern China (Dongbei), with major cities including Tongliao, Chifeng, Hailar, and Ulanhot. The western division is included in North China, with major cities including Baotou and Hohhot. It recorded a population of 24,706,321 in the 2010 census, accounting for 1.84% of Mainland China's total population. Inner Mongolia is the country's 23rd most populous province-level division. Han Chinese make up the majority of the population in the region; Mongols constitute a significant minority with over 4 million people, making it the largest Mongol population in the world (larger than that of the country Mongolia). Inner Mongolia is one of the more economically developed provinces in China with annual GDP per capita at US$14,343 (2022), ranked 8th in the nation. As of 2021, Mandarin is the region's sole official language. In the region, Mongolian is written in the traditional Mongolian script, as opposed to the Mongolian Cyrillic alphabet, which is used alongside the traditional script in the country of Mongolia (formerly described as Outer Mongolia).

Etymology

In Chinese, the region is known as "Inner Mongolia", where the terms of "Inner" and "Outer" are derived from Manchu dorgi and tulergi (cf. Mongolian dotugadu and gadagadu). Inner Mongolia is distinct from Outer Mongolia, which was a term used by the Republic of China and previous governments to refer to what is now the independent state of Mongolia and the Republic of Tuva in Russia.

Due to the perceived Sinocentric nature of the name "Inner Mongolia", some Mongols outside of China, particularly those in the state of Mongolia and separatist groups in the West, prefer the name "Southern Mongolia". However, this name has not been adopted officially by any government bodies.

History

Much of what is known about the history of the Mongolian Plateau is taken from Chinese chronicles and historians. Before the rise of the Mongols in the 13th century, what is now central and western Inner Mongolia, especially the Hetao region, alternated in control between Chinese farming communities in the south, and Xiongnu, Xianbei, Khitan, Jurchen, Tujue, and nomadic Mongol of the north. The historical narrative of what is now Eastern Inner Mongolia mostly consists of alternations between different Tungusic and Mongol tribes, rather than the struggle between nomads and Chinese farmers.

Early history

Slab Grave cultural monuments are found in Northern, Central and Eastern Mongolia, Inner Mongolia, North-Western China, Southern, Central-Eastern and Southern Baikal territory. Mongolian scholars prove that this culture related to the Proto-Mongols.History of Mongolia, Volume I, 2003.

During the Zhou dynasty, Central and Western Inner Mongolia (the Hetao region and surrounding areas) were inhabited by nomadic peoples such as the Loufan, Linhu and Dí, while Eastern Inner Mongolia was inhabited by the Donghu. During the Warring States period, King Wuling (340–295 BC) of the state of Zhao based in what is now Hebei and Shanxi Provinces pursued an expansionist policy towards the region. After destroying the Dí state of Zhongshan in what is now Hebei province, he defeated the Linhu and Loufan and created the Yunzhong Commandery near modern Hohhot. King Wuling of Zhao also built a long wall stretching through the Hetao region. After Qin Shi Huang created the first unified Chinese empire in 221 BC, he sent the general Meng Tian to drive the Xiongnu from the region and incorporated the old Zhao wall into the Qin dynasty Great Wall of China. He also maintained two commanderies in the region: Jiuyuan and Yunzhong and moved 30,000 households there to solidify the region. After the Qin dynasty collapsed in 206 BC, these efforts were abandoned.Records of the Grand Historian by Sima Qian.

During the Western Han dynasty, Emperor Wu sent the general Wei Qing to reconquer the Hetao region from the Xiongnu in 127 BC. After the conquest, Emperor Wu continued the policy of building settlements in Hetao to defend against the Xiong-Nu. In that same year, he established the commanderies of Shuofang and Wuyuan in Hetao. At the same time, what is now Eastern Inner Mongolia was controlled by the Xianbei, who would, later on, eclipse the Xiongnu in power and influence.

During the Eastern Han dynasty (25–220 AD), Xiongnu who surrendered to the Han dynasty began to be settled in Hetao and intermingled with the Han immigrants in the area. Later on, during the Western Jin dynasty, it was a Xiongnu noble from Hetao, Liu Yuan, who established the Han Zhao kingdom in the region, thereby beginning the Sixteen Kingdoms period that saw the disintegration of northern China under a variety of Han and non-Han (including Xiongnu and Xianbei) regimes.

The Sui dynasty (581–618) and Tang dynasty (618–907) re-established a unified Chinese empire and like their predecessors, they conquered and settled people into Hetao, though once again these efforts were aborted when the Tang empire began to collapse. Hetao (along with the rest of what now consists Inner Mongolia) was then taken over by the Liao dynasty founded by the Khitans, a nomadic people originally from what is now the southern part of Manchuria and Eastern Inner Mongolia. They were followed by the Western Xia of the Tanguts, who took control of what is now the western part of Inner Mongolia (including Western Hetao). The Khitans were later replaced by the Jurchens, precursors to the modern Manchus, who established the Jin dynasty over Manchuria and Northern China.

Mongol and Ming periods

After Genghis Khan unified the Mongol tribes in 1206 and founded the Mongol Empire, the Tangut Western Xia empire was ultimately conquered in 1227, and the Jurchen Jin dynasty fell in 1234. In 1271, Kublai Khan, the grandson of Genghis Khan established the Yuan dynasty. Kublai Khan's summer capital Shangdu (aka Xanadu) was located near present-day Dolonnor. During that time Ongud and Khunggirad peoples dominated the area of what is now Inner Mongolia. After the Yuan dynasty was overthrown by the Han-led Ming dynasty in 1368, the Ming captured parts of Inner Mongolia including Shangdu and Yingchang. The Ming rebuilt the Great Wall of China at its present location, which roughly follows the southern border of the modern Inner Mongolia Autonomous Region (though it deviates significantly at the Hebei-Inner Mongolia border). The Ming established the Three Guards composed of the Mongols there. Soon after the Tumu incident in 1449, when the Oirat ruler Esen taishi captured the Chinese emperor, Mongols flooded south from Outer Mongolia to Inner Mongolia. Thus from then on until 1635, Inner Mongolia was the political and cultural centre of the Mongols during the Northern Yuan dynasty.CPAtwood-Encyclopedia of Mongolia and the Mongol Empire, p. 246.

Qing period

The eastern Mongol tribes near and in Manchuria, particularly the Khorchin and Southern Khalkha in today's Inner Mongolia intermarried, formed alliances with, and fought against the Jurchen tribes until Nurhaci, the founder of the new Jin dynasty, consolidated his control over all groups in the area in 1593.Atwood, Christopher. Encyclopedia of Mongolia and the Mongol Empire, p. 449. The Manchus gained far-reaching control of the Inner Mongolian tribes in 1635, when Ligden Khan's son surrendered the Chakhar Mongol tribes to the Manchus. The Manchus subsequently invaded Ming China in 1644, bringing it under the control of their newly established Qing dynasty. Under the Qing dynasty (1644–1912), the Mongolian Plateau was administered in a different way for each region:

"Outer Mongolia": This region corresponds to the modern state of Mongolia, plus the Russian-administered region of Tannu Uriankhai, and modern-day aimag of Bayan-Ölgii which historically was a part of northern Xinjiang under China's Qing Dynasty. It included the four leagues (aimag) of the Khalkha Mongols north of the Gobi Desert, as well as the Tannu Uriankhai which largely corresponds to modern-day Tuva Republic of Russia, and Khovd regions in northwestern Mongolia, which were overseen by the General of Uliastai from the city of Uliastai. "Inner Mongolia": This region corresponded to most of modern Inner Mongolia and some neighbouring areas in Liaoning and Jilin provinces. The banners and tribes in this region came under six leagues (chuulghan): Jirim, Juuuda, Josutu, Xilingol, Ulanqab, and Yekejuu. "Taoxi Mongolia": The Alashan Öölüd and Ejine Torghuud banners were separate from the aimags of Outer Mongolia and the chuulghans of Inner Mongolia. This territory is equivalent to modern-day Alxa League, the westernmost part of what is now Inner Mongolia. The Chahar Banners were controlled by the military commander of Chahar (now Zhangjiakou). Their extent corresponded to southern Ulanqab and Bayannur in modern Inner Mongolia, plus the region around Zhangjiakou in Hebei province. At the same time, the jurisdiction of some border departments of Zhili and Shanxi provinces also belonged to this region. The Guihua Tümed banner was controlled by the military commander of Suiyuan (now Hohhot). This corresponds to the vicinities of the modern city of Hohhot. At the same time, the jurisdiction of some border departments of modern Shanxi province also belonged to this region. The Hulunbuir region in what is now northeastern Inner Mongolia was part of the jurisdiction of the General of Heilongjiang, one of the three generals of Manchuria.

The Inner Mongolian Chahar leader Ligdan Khan, a descendant of Genghis Khan, opposed and fought against the Qing until he died of smallpox in 1634. Thereafter, the Inner Mongols under his son Ejei Khan surrendered to the Qing. Ejei Khan was given the title of Prince (), and Inner Mongolian nobility became closely tied to the Qing royal family and intermarried with them extensively. 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 arrest 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 revolt was put down within two months, the Qing then crushed the rebels in a battle on 20 April 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.
