Drogön Chögyal Phagpa was the spiritual advisor and guru to Kublai Khan. In 1260, Kublai appointed Chögyal Phagpa as "Guoshi", or State Preceptor, in 1260, the year when he became Khagan. Phagpa was the first "to initiate the political theology of the relationship between state and religion in the Tibeto-Mongolian Buddhist world". With the support of Kublai Khan, Chögyal Phagpa established himself and his sect as the preeminent spiritual leader in Tibet, and in the wider Mongol Empire. In 1265 Drogön Chögyal Phagpa returned to Tibet and for the first time made an attempt to impose Sakya hegemony with the appointment of Shakya Bzang-po, a long time servant and ally of the Sakyas, as the Mongol approved dpon-chen, or great administrator, over Tibet in 1267. A census was conducted in 1268 and Tibet was divided into thirteen myriarchies. While maintaining administrative control through the dpon-chen, Kublai's relationship with the Sakya Lama became known in the Tibetan tradition as the patron and priest relationship. Subsequently, each Yuan emperor had a Lama as a spiritual guide.
