Claim: Drogön Chögyal Phagpa (first Imperial Preceptor of Kublai Khan's Yuan dynasty) was named the Bureau of Buddhist and Tibetan Affairs director, which managed Tibet during the Mongolian Empire.
Evidence: He was also the first Imperial Preceptor of Kublai Khan's Yuan dynasty, division of the Mongol Empire, and was concurrently named the director of the Bureau of Buddhist and Tibetan Affairs. In the Mongol Empire, Tibet was managed by the Bureau of Buddhist and Tibetan Affairs, separate from the other provinces of the Yuan dynasty such as those governed the former Song dynasty of China, but still under the administrative rule of the Yuan.
