Powo
Powo, or Poyul, was a kingdom in the forested gorges of southeastern Tibet, centred on Kanam. Founded in the thirteenth century, its rulers claimed descent from the early Yarlung king Drigum Tsenpo.
In 1717 a Dzungar army burned the palace at Kanam; the Kashag later imposed governors and corvée in the lower valleys. When the king died without an heir in 1821, local chiefs divided the land. After a revolt in 1835, Qing troops intervened and confirmed a new Kanam Depa in 1836.
