Tolui
Tolui (c.1191–1232) was the fourth son of Genghis Khan by his chief khatun Börte. His ulus, or territorial inheritance, at his father's death in 1227 was the homelands in Mongolia, and it was he who served as civil administrator until 1229, the time it took to confirm Ögedei as second Great Khan of the Mongol Empire (1206–1368). Before that he had served with distinction in the campaigns against the Jin dynasty, the Western Xia and the Khwarezmid Empire, where he was instrumental in the capture and massacre at Merv and Nishapur. He is a direct ancestor of most of the Ilkhanids.
