固始汗
Tibet was invaded by Mongols during the Yuan dynasty. In 1642, the Khoshut local government was established by Güshi Khan, a Khoshut prince and leader of the Upper Mongols. He reunified Tibet under the political and spiritual authority of the 5th Dalai Lama as leader of Tibet. With Güshi Khan as a largely uninvolved overlord, the Dalai Lama and his colleagues established a civil governmental body referred to as the Ganden Phodrang.
