The story behind the mythic brutality of Genghis Kahn, one of the most successful leaders in human history. A new title in the series created for the modern reader, introducing the heroes, cultures, myths and religions of the world. The tale of the legendary Mongol General Genghis Khan is as phenomenal as the man himself. Probably the greatest conqueror in history, he ruled vast swathes of land in the early 1200s, vanquishing people across Asia and Europe, so that by the mid-1200s the Mongol Empire covered over 12 million square miles of land.
