固始汗
The 5th Dalai Lama (r. 1642–1682) is known for unifying the Tibetan heartland under the control of the Gelug school of Tibetan Buddhism, after defeating the rival Kagyu and Jonang sects and the secular ruler, the Tsangpa prince, in a prolonged civil war. His efforts were successful in part because of aid from Güshi Khan, the Oirat leader who established the Khoshut Khanate. With Güshi Khan as a completely uninvolved patron, who had conferred supreme authority on the Dalai Lama for the whole of Tibet at a ceremony at Tashilhunpo Monastery in Shigatse, the 5th Dalai Lama and his intimates established a civil administration which is referred to by historians as the "Lhasa state". All power and authority lay in the hands of the Dalai Lama right up to his death and Güshi Khan did not interfere in the administration nor tried to control its policies. The core leadership of this government is also referred to as the "Ganden Phodrang" or "Ganden Podrang", derived from the name of the estate of the Dalai Lamas at Drepung Monastery.
