Gyelrong
Gyelrong was a region of Gyalrong chiefdoms in the upper Dadu gorges of northwestern Sichuan. Hereditary chiefs ruled the area.
Bön dominated until Gelug missionaries from central Tibet arrived in the early 15th century and founded monasteries such as Dhe-Tsang despite Bön opposition. In 1747 Slob Dpon of Greater Jinchuan attacked Chakla and surrendered to the Qing in 1749. A second war ended in 1776, when Qing forces defeated Sonom after a five-year campaign.
