Hachiun

The Hachiun horde was the eastern appanage of Genghis Khan's brother Hachiun and his descendants. In 1337 a Borjigin prince, Munanzi, ruled around Qingzhou in the Songnen region under the Yuan great khan.

After the Yuan fell in 1368, Ming power reached the eastern Mongol borderlands. In 1389 the Ming established the Three Guards and gave Borjigin princes descended from Genghis Khan's brothers command of the Taining Guard.
