The Uighur empire

This new empire comprised many tribes and seems to have been headed by a smaller tribal confederation standing under Uighur leadership. This federation is referred to in Chinese sources as the Nine Clans (Jiuxing), whereas Islamic sources and the Orhon inscriptions call it the Tokuz Oğuz. There are some indications that the Uighur empire stood under dual leadership, the khagan belonging to one tribe and the prime minister, in whose hands much of the effective power rested, to another.

Relations with China were the dominant factor in Uighur foreign affairs. The Uighurs proved somewhat less threatening for the Chinese than had the Xiongnu or the Turks. Their help to the Chinese, plagued by the rebellion of An Lushan (755) and by repeated Tibetan incursions, was appreciated and paid for through trade conducted on terms unfavourable to China. In exchange for Uighur horses, often of dubious quality, the Chinese were expected to provide the Uighurs with much-coveted riches. The third Uighur khagan—Mouyu by his Chinese name (759–780)—visited Luoyang in China, where he was converted to an Iranian religion, Manichaeism. Its adoption brought to the Uighur land many Sogdians, whose growing influence on state affairs was resented by the Turkic Uighurs and led to Mouyu’s assassination.

The Uighur empire was governed from a city on the Orhon River, Karabalghasun, the foundations of which were probably laid by the Turks and can still be seen. A Muslim traveler, Tamīm ibn Baḥr, who visited the city about 821, speaks in admiring terms of this fortified town lying in a cultivated country—a far cry from the traditional picture of the pastoral nomad existence.
