Yesugei

Yesugei Baghatur led the Borjigin family as a major chief of the Khamag Mongol confederation in the mid-12th century. His name meant "like nine" — the Mongols considered nine a lucky number, and he was thought to carry its auspicious qualities. He died in 1171, when his son Temüjin was still a boy. What followed that early death — the empire Temüjin would build — rewrote the map of Asia, but Yesugei himself never saw it.
