Tibet under Yuan rule

Tibet under Yuan rule refers to the Mongol-led Yuan dynasty's rule over Tibet from approximately 1270 to 1354. During the Yuan dynasty, Tibet was administered by an organization that was structurally, militarily and administratively subordinate to the Yuan court. Tibet was conquered by the Mongols led by a general titled doord darkhan in 1240 and Mongol rule was established after Sakya Pandita obtained power over Tibet through the Mongols in 1244. This period and administration has been called the Sakya dynasty (Tibetan: ས་སྐྱ་, Wylie: sa skya, Chinese: 薩迦王朝; pinyin: Sàjiā Wángcháo) after the favored Sakya school of Tibetan Buddhism.

The region retained a degree of political autonomy under the Sakya lama, who was the de jure head of Tibet and a spiritual leader of the Mongol Empire under the priest and patron relationship. However, administrative and military rule of Tibet remained under the auspices of the Yuan government agency known as the Bureau of Buddhist and Tibetan Affairs (Xuanzheng Yuan), a top-level administrative department separate from other Yuan provinces, but still under the administration of the Yuan dynasty. Tibet retained nominal power over religious and political affairs, while the Yuan dynasty managed a structural and administrative rule over the region, reinforced by the rare military intervention. This existed as a "diarchic structure" under the Yuan emperor, with power primarily in favor of the Mongols. One of the department's purposes was to select a dpon-chen, the de facto administrator and imperial representative in Tibet, usually appointed by the lama and confirmed by the Yuan emperor in Dadu (modern-day Beijing).
