Gusiluo
Gusiluo was a Tibetan king of Tsongkha, in present-day Qinghai and parts of Hexi Corridor. Claimed to be a descendant of Buddha, Guosiluo laid a foundation to a large Tibetan confederacy centered in Zongge. The Gusiluo regime built a closed relationship with the Khitans to resist the increasing powerful Western Xia.
In 1099, the Northern Song launched a campaign into Xining and Haidong, occupying territory that was controlled by the Tibetan Gusiluo regime since the 10th century.
