The Mongols invade China from the north, defeat the Song, and establish the Yuan dynasty in 1279, ruling less than one-hundred years, to 1368. Under Khubilai (Kublai) Khan (1215-1294), the supreme leader of the Mongols and a grandson of Chinggis (Genghis) Khan (d. 1227), the Mongols move the Chinese capital to Beijing and establish the capital of their empire there.
