Ongud

thumb|Mongol Empire c.1207, Ongud and their neighbours The Ongud (also spelled Ongut or Öngüt; Mongolian: Онгуд, Онход; Chinese: 汪古, Wanggu; from Old Turkic öng "desolate, uninhabited; desert" plus güt "class marker") were a Turkic tribe that later became part of various Turkic and Mongolic peoples. They were active in what is now Inner Mongolia in northern China around the time of Genghis Khan (1162–1227). Many Ongud were members of the Church of the East. They lived in an area lining the Great Wall in the northern part of the Ordos Plateau and territories to the northeast of it. They appear to have had two capitals, a northern one at the ruin known as Olon Süme and another a bit to the south at a place called Koshang or Dongsheng. They acted as wardens of the marches for the Jin dynasty (1115–1234) to the north of Shanxi.

==History== ===Origin=== The ancestors of the Ongud were the Shatuo Turks, who, in turn, descended mainly from the two remnant tribes of Western Turkic Khaganate: namely, the Chuyue, the Türgesh-associated Suoge, and the Anqing of Sogdian origins. In the seventh century they moved to east of modern Dzungaria, then under the rule of the Tang dynasty. By the ninth century, the Shatuo were scattered over north Shanxi and modern Inner Mongolia. In 808, 30,000 Shatuo under Zhuye Jinzhong defected from the Tibetans to Tang China and the Tibetans punished them by killing Zhuye Jinzhong as they were chasing them. The Uyghurs also fought against an alliance of Shatuo and Tibetans at Beshbalik. The Shatuo Turks under Zhuye Chixin (Li Guochang) served the Tang dynasty in fighting against their fellow Turkic people in the Uyghur Khaganate. In 839, when the Uyghur khaganate (Huihu) general Jueluowu (掘羅勿) rose against the rule of then-reigning Zhangxin Khan, he elicited the help from Zhuye Chixin by giving Zhuye 300 horses, and together, they defeated Zhangxin Khan, who then committed suicide, precipitating the subsequent collapse of the Uyghur Khaganate. In the next few years, when Uyghur Khaganate remnants tried to raid Tang borders, the Shatuo participated extensively in counterattacking the Uyghur Khaganate with other tribes loyal to Tang. In 843, Zhuye Chixin, under the command of the Han Chinese officer Shi Xiong with Tuyuhun, Tangut and Han Chinese troops, participated in a raid against the Uyghur khaganate that led to the slaughter of Uyghur forces at Shahu mountain. A Shatuo warlord, Li Keyong, mobilized 10,000 Shatuo cavalrymen and served the Tang dynasty as an ally. In 923, his son Li Cunxu defeated the Later Liang dynasty and became emperor of the Later Tang dynasty.
