The Khoshut Khanate was conquered by the troops of the Dzungar Khanate in 1717, who deposed Yeshe Gyatso, a pretender to the position of the Dalai Lama promoted by Lha-bzang Khan, the last ruler of the Khoshut Khanate. The Dzungars were in turn expelled by the expedition forces of the Qing dynasty from Tibet in 1720, and Tibet was unified with Qing China. (See Qing conquest of Tibet.)
