Tsakho

Tsakho, or Zagunao, was a hereditary Gyalrong chiefdom in the valleys of present-day Sichuan, with its seat at Zagunao.

In 1407 its headman Apiao submitted to the Ming. Muping invaded in 1449, but Tsakho recovered its lands by 1469. Under Sangjipeng and his son Liang'erji it absorbed smaller chiefdoms and by 1683 ruled over ten thousand households. The Qing separated Somang in 1721 and Choktse and Tangpa in 1748. In 1752 Cangwang revolted, was captured and executed; the court replaced the chiefdom with Zagu Subprefecture.
