固始汗
The "Ganden Phodrang" was the Tibetan regime or government that was established by the 5th Dalai Lama with the help of the Güshi Khan of the Khoshut in 1642. After the civil war in the 17th century and the Mongol intervention, the Gelugpa school dominated Tibetan Buddhism, and successive Dalai Lamas ruled Tibet from the mid-17th to mid-20th centuries.
