"Genghis Khan" In the 12th century, Koholen was taken as a bride by Yesukai from the Naiman tribe to the Mongol Qiyang tribe. Amidst the constant warfare and feuds among various tribes, she gave birth to young Temujin. The one who assisted in his birth was from the Tatar tribe, the hereditary enemy of the Mongol Qiyang tribe. It was also a member of this Tatar tribe who later killed Temujin's father.
