Rouran Khaganate
A the time of its conquest by the Rouran Khaganate, there were more than ten thousand Han Chinese households in Gaochang. The Rouran Khaganate, which was based in Mongolia, appointed a Han Chinese named Kan Bozhou to rule as King of Gaochang in 460, and it became a separate vassal kingdom of the Khaganate. Kan was dependent on Rouran backing. Yicheng and Shougui were the last two kings of the Chinese Kan family to rule Gaochang.
