He not only managed to unite many disparate tribes, but his invasions culminated in the conquest of northern China, leaving him with a kingdom the size of Africa. His ruthless military campaigns certainly earned him the title he gave himself: "barbarian from the North." While he could be brutal . he also brought about a time of peace and prosperity for the Mongols.
