#39  Genghis Khan

During his short but expansive reign, he brought millions of souls under the banner of the Mongol Empire. Riding and fighting on horseback, he and his horde advanced into Persia, eastern Europe and China with such ferocity that even long after his reign had ended, the mere mention of his name would make men shudder, women weep, and children hide. Such was the reputation of the great Genghis Khan.
