Kitan and Jurchen

Free of Uighur restraint, the Kitan expanded in all directions in the latter half of the ninth century and the early years of the tenth century. By 925 the Kitan ruled eastern Mongolia, most of Manchuria, and much of China north of the Huang He. In the recurrent process of sinicization, by the middle of the tenth century Kitan chieftains had established themselves as emperors of northern China; their rule was known as the Liao Dynasty (916-1125).

The people of Mongolia at this time were predominantly spirit worshipers, with shamans providing spiritual and religious guidance to the people and tribal leaders. There had been some infusion of Buddhism, which had spread from Xinjiang, but it did not yet have a strong influence (see The Yuan Dynasty; Return to Nomadic Patterns). Nestorian Christianity also had penetrated Inner Asia.

In the eleventh century, the Kitan completed the conquest of China north of the Huang He. Despite close cultural ties between the Kitan and Western Xia that led the latter to become increasingly sinicized, during the remainder of that century and the early years of the twelfth century, the two Mongol groups were frequently at war with each other and with the Song Dynasty (A.D. 960-1279) of China. The Uighurs of the Turpan region often were involved in these wars, usually aiding the Chinese against Western Xia.

A Tungusic people, the Jurchen, ancestors of the Manchu, formed an alliance with the Song and reduced the Kitan Empire to vassal status in a seven-year war (1115-1122; see Caught Between the Russians and the Manchus). The Jurchen leader proclaimed himself the founder of a new era, the Jin Dynasty (1115-1234). Scarcely pausing in their conquests, the Jurchen subdued neighboring Koryo (Korea) in 1226 and invaded the territory of their former allies, the Song, to precipitate a series of wars with China that continued through the remainder of the century. Meanwhile, the defeated Kitan Liao ruler had fled with the small remnant of his army to the Tarim Basin, where he allied himself with the Uighurs and established the Karakitai state (known also as the Western Liao Dynasty, 1124-1234), which soon controlled both sides of the Pamir Mountains. The Jurchen turned their attention to the Mongols who, in 1139 and in 1147, warded them off.
