Using the Dalai Lama's behaviour as an excuse and with the approval of his ally, China's Kangxi Emperor, Lha-bzang Khan, khan of the Khoshut, killed the regent and kidnapped the Sixth Dalai Lama. On 28 June 1706, Lha-bzang Khan deposed Tsangyang; he later installed a 21-year-old lama, Ngawang Yeshey Gyatso, as the "true" 6th Dalai Lama in 1707, claiming that he, not Tsangyang, was the true rebirth of the 5th Dalai Lama. The Gelugpa dignitaries and the Tibetan people rejected Lha-bzang Khan's installation of Ngawang Yeshey Gyatso and continued to recognise Tsangyang's title. However, Ngawang Yeshey Gyatso is considered by Tibetans to have been an incarnation of Avalokiteśvara.
