Tashan

Tashan was a Haixi Jurchen polity in the Hulan and Songhua river country, where southward-moving Weji groups formed the Hulun.

Under the Ming, its clans were registered as the Tashan Guard and later the Tashan Left Guard. After its Nara commander Keshina was killed by his own people, his son Wangji Wailan led the clan south and founded Hada near Kaiyuan; another Nara branch founded Ula. Hada weakened after Chief Wan died in 1582, and Nurhaci took it in 1599 and annexed it in 1601. Ula fell to the Jianzhou in 1613.
