Sakya is the name of a monastery and of a major tradition of Tibetan Buddhism that originated there during the Later Diffusion of Buddhism. Sakya Monastery was the seat of power during Sakya-Mongol rule in Tibet (1260–1350s), founded on the priest-patron relationship. Notable Sakya figures include Sakya Pandita (1182–1251), who played an instrumental role in establishing Tibetan relations with the Mongols; Drogon Chogyel Pakpa (1234-1280), who served as Qubilai Khan’s imperial preceptor and invented the Pakpa Script; and Buton (1290–1364), who compiled the Tibetan Canon. The Sakya are particularly known for their Lamdre teachings. In the 1350s, Pakmodru replaced the Sakya political prominence.
