Amdo

Amdo was the northeastern Tibetan region, extending from Lake Qinghai to the Yangtze headwaters. The Mongols conquered it in the thirteenth century.

Mongol authority weakened, and in 1347 rebellion broke out across eastern Tibet. The Ming later controlled parts of Amdo's eastern border, while Mongols regained power in the grasslands. In 1642 Gushri Khan established the Fifth Dalai Lama's rule in Tibet while his Kokonor base remained Mongol. In the 1720s the Qing seized Amdo and governed much of it through local Tibetan rulers.
