With support from his allies and his father's former followers, Temüjin becomes the leader of the Borjigin tribe and emerges as one of the most powerful warlords in Mongolia. After spending decades on the battlefield, Temüjin eventually succeeds in uniting all the Mongol tribes under his rule and adopts the honorific title "Genghis Khan" (means "supreme ruler" in the Mongol language). Genghis Khan continues to lead his armies to attack the Khwarezmid Empire in the west and the Jurchen-led Jin Empire in the south before dying from illness during a campaign against the Western Xia kingdom.
