The Ongud, ( Mongol: Онгуд, untouchables) were Mongols active in Mongolia around the time of Genghis Khan (1162–1227). Many members were members of the Church of the East. They lived in an area lining the Great Wall in the northern part of the Ordos Loop 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 the province Shanxi.
The ancestors of the Ongud were the Yueban who later intermixed with Turkic peoples, forming the Shatuo of the Western Turkic Khaganate. In the 7th century they moved to eastern Xinjiang under the protection of the Tang Dynasty. By the 9th century the Shato were scattered over North China and modern Inner Mongolia. A Shato warlord, Li, mobilized 10,000 Shato cavalrymen and served the Tang as ally. In 923 his son defeated the rebellious dynasty and became emperor of the Later Tang. After the overthrow of the Li family, Shatuo commanders established the Later Jin, the Later Han and the Northern Han.
In the 13th century a part of Shato probably included in the Mongol Empire as an Ongut tribe, another part as White Tatars. During Mongolian time, a part of the Chuy Onguts were resettled in Khorazm, to eventually become a part of Kazakhs, and another fraction remained in Mongolia, in the 15th century they became part of the Tumed.
The Ongud chief Alakush tegin revealed the Naimans plan to attack Genghis in 1205 and allied with the Mongols. When Genghis Khan invaded the Jin Dynasty in 1211, Alagush tegin (Alakush tegin) supported him. Genghis bestowed his daughter Alaga bekhi (Alaqai beki) on his son. However, the political opponents killed Alagush. Genghis put down the rebellion and took the family under his protection. Genghis Khan's daughter Alaga ruled the Ongud people as regent for several underage princes until the reign of Güyük Khan (1246–48).
Many famous post-Genghis Mongols are of Ongud descent, including the well-known monk, traveler, and diplomat, Rabban Bar Sauma (1220–1294). The Ongud proved good allies to Kublai. For example, the Ongud ruler Korgiz (George) married Kublai's two granddaughters and fought against Kaidu, whose protégé Duwa captured and killed him later in 1298. A number of Öngüd were said to have been converted to Catholicism by John of Montecorvino (1246–1328).
After 1221 many Onguds were resettled in Khwarezm where they served as governors for the Golden Horde. They formed part of the Argyns and the Mughal tribe. Onguds in Mongolia became an otog of the Tumed in the 15th century.
The University of Hong Kong possesses a collection of around a thousand 13th- and 14th-century bronze Nestorian crosses from the Ongud region collected during the 1920s by F. A. Nixon, a British postal official working in northern China. Although their designs vary, Maltese crosses with a square central panel displaying a swastika, the Buddhist good luck symbol, predominate.
The Ongud Monument Ensemble was constructed by the Turkic tribes during the 6th-8th centuries for their noblemen. This consists of over 30 man-like figures, a lion and a sheep, and about 550 standing stones in alignments reminiscent of Carnac or Avebury. There is also a large tomb made of 4 sculptured slabs. Each slab has the front face decorated with a trellis-pattern like the walls of a ger, and a simple frieze on top.
