固始汗
Dayan Khan was the son of Güshi Khan of the Khoshut tribe who allied with the Gelug faction (the Yellow Church) in Tibet and was victorious in 1642. Güshi had offered the earth, tribes and people of the three "cholka" of Tibet to the Gelug leader, the 5th Dalai Lama. The Dalai Lama, in return, named him Dharma king, Protector of the Faith. The Khoshut khan did not normally interfere in political matters, but rather managed the Mongol forces that backed up the dharma regime of Dalai Lama. Güshi Khan and his sons were known as "the father and son kings of the Mongolian government".
