The title was originally created as the State Preceptor or Guoshi (, lit. "Teacher of the State") in 1260, the first year of Kublai Khan's enthronement. In that year he appointed the Sakya lama Drogön Chögyal Phagpa to this post and soon placed him in charge of all Buddhist clergy. In 1264, he founded the Bureau of Buddhist and Tibetan Affairs and appointed Phagpa as the first director of this important new agency. The lama was offered nominal rule over all Tibet and also supervised Mongol relations with the Buddhist clergy. In 1270, Phagpa became Imperial Preceptor (Dishi) when the title was renamed. As Imperial Preceptor, he was authorized to issue letters and proclamations to the temples and institutions of Tibet, and he advised the Emperor regarding official appointments in Tibet. Kublai Khan dispatched the lama to Tibet in 1264 to help persuade his people to accept Mongol rule.
