The Yuan dynasty (1271–1368) is the branch of the Mongol Empire in Asia. In 1260 when Qubilai Khan declared himself Great Khan, his realm included Mongolian, Chinese, Tangut, and Tibetan regions. In 1271 emperor Qubilai Khan proclaimed the Yuan dynasty on a Chinese model, employing Tibetan and Tangut monks. Tibetan Buddhism played an important role in the state, establishing a political model that would be emulated by later dynasties, including the Chinese Ming and Manchu Qing dynasties. The Mongols were major patrons of Tibetan institutions, and many Mongols converted to Tibetan Buddhism, though their interest declined with the fall of the empire.
