Nubhor

Nubhor, or Western Hor, comprised Tibetanised Mongol pastoral tribes on the upper Salween grasslands, around Biru, Sog, Tengchen and Riwoche. Their highland pastures lay between Chamdo and the Nagchu plateau, under Lhasa's loose overlordship.

Under the Qing these groups were registered as the Thirty-nine Hor Tribes, with four thousand eight hundred and eighty-nine households recorded in 1731. By the late eighteenth century a supreme Thousand-Household chief oversaw thirteen Hundred-Household chiefs and fifty-three headmen; an official under the Lhasa amban managed horse tribute and disputes.
