[Q]: Question: How long did the Eurasian empire that rose in the thirteenth century last? Passage:Vajrayana had also become the major religion of Tibet and the Western Xia by the time of the rise of the Mongol Empire in the thirteenth century. As the Tibetan and Tangut peoples came under the rule of Mongol leaders during the reign of Mongke Khan (12091259), they increased their missionary activity in Mongolian lands, eventually converting the leadership and much of the population as well aiding in the translation of Buddhist texts into Mongolian. So it is no surprise that after the Mongol conquest of China and their establishment of the Yuan dynasty (12711368), the Yuan emperors made Tibetan Buddhism the official religion of China, and Tibetan monks (or, as they were called in Chinese, "barbarian monks from the West", ) were given patronage at the court. Lamas of the Sakya school like Sakya Pandita and also of the Kagyu became imperial preceptors of the Mongol Khans. The tantric deity Mahakala was used in military campaign to protect the armies during their war against China and became the protector deity of the Yuan state. They were granted unprecedented status and privileges such as temple offerings and shrines.
