Yuan Dynasty, a Mongol dynasty, was founded by the Mongol leader Kublai Khan. He ruled most of present-day China, and all of modern Mongolia and its surrounding areas from 1271 to 1368. It was considered a division of the Mongol Empire and at the same time an imperial dynasty of China. Although he established the Yuan dynasty, he put his grandfather Genghis Khan’s name on the official record as the founder of the dynasty. Kublai Khan introduced many administrative and economic reforms during his reign.
