Yesugei

Yesugei (c. 1134–1171), called Baghatur, was a Borjigin chieftain of the Khamag Mongol confederation and father of Genghis Khan. A grandson of Khabul Khan, he ruled the confederation in all but name after Hotula Khan died. He abducted Hö'elün from her Merkit husband; she bore Temüjin, Qasar, Hachiun and Temüge.

In 1171, after betrothing the nine-year-old Temüjin to Börte of the Khongirad, Tatars poisoned him at a wayside feast, and he died at home three days later.
