Otchigin

The Otchigin appanage descended from Temüge, Genghis Khan’s youngest brother. In 1337 his descendants grazed around Taizhou in Songnen under Borjigin princes.

After the Yuan fell in 1368, the Ming established the Three Guards in 1389, placing the Taining Guard under Borjigin princes descended from Genghis Khan’s brothers. Most guards fled Esen Tayisi’s invasions in 1446 to 1448, though the Fuyu Guard remained along the Nen and Onon rivers.
