In 1703 Güshi Khan's ruling grandson Tenzin Wangchuk Khan was murdered by his brother Lhazang Khan who usurped the Khoshut's Tibetan throne, but unlike his four predecessors he started interfering directly in Tibetan affairs in Lhasa; he opposed the Fifth Dalai Lama's regent, Desi Sangye Gyatso for his deceptions and in the same year, with the support of the Kangxi Emperor, he forced him out of office. Then in 1705, he used the Sixth's escapades as an excuse to seize full control of Tibet. Most Tibetans, though, still supported their Dalai Lama despite his behaviour and deeply resented Lhazang Khan's interference. When Lhazang was requested by the Tibetans to leave Lhasa politics to them and to retire to Kokonor like his predecessors, he quit the city, but only to gather his armies in order to return, capture Lhasa militarily and assume full political control of Tibet. The regent was then murdered by Lhazang or his wife, and, in 1706 with the compliance of the Kangxi Emperor the Sixth Dalai Lama was deposed and arrested by Lhazang who considered him to be an impostor set up by the regent. Lhazang Khan, now acting as the only outright foreign ruler that Tibet had ever had, then sent him to Beijing under escort to appear before the emperor but he died mysteriously on the way near Lake Qinghai, ostensibly from illness.
