Kumo XI - Conflict With The Tang Dynasty

Conflict With The Tang Dynasty

By the early Tang period (around the 7th century AD), the (now named) Xi had become subordinate to the Khitans. After the Khitans' Li-Sun Rebellion (696-697) and Ketuyu revolt (730-734), the Xi regained their position of dominance. The Xi then entered a golden age, lasting from approximately 755 to 847. During this period the Xi were friendly with An Lushan, and supported An in his An Shi Rebellion (756-763), plundering Han territories frequently within this period. This aggressive policy seems to have consumed Xi forces, especially weakening their demographic vitality, allowing the less aggressive Khitans to dominate them. Xi raids into China provoked successive heavy responses from the Tang, resulting in battles in the 760s and in 795 that were disastrous for the Xi. After 795, the Xi became a tributary people to the Tang.

The Uyghur Empire (744-840) collapsed in the 840's. When the Tang dynasty simultaneously displayed signs of division, the Xi rose in rebellion in 847, and were subsequently and disastrously defeated by Zhang Zhongwu, the frontier commander of Lulong. The Xi were never able to recover from their defeat in 847. In the late ninth century AD the Khitans rose to eventually absorb the remnants of Xi people, and established the Liao Dynasty in 907.
