“ In the year 1156 was born their greatest chieftain, Temujin, afterwards named Genghis Khan, or "Universal Sovereign," the most terrible scourge that ever afflicted the human race. At the head of vast armies, made up of numerous Turanian hordes, he traversed with sword and torch a great part of Asia. It is estimated that his enormous empire was built up at the cost of fifty thousand cities and towns and five millions of lives,—a greater waste, probably, than resulted from all the Crusades. ”
