In the space of 200 hundred years, the Mongols built the greatest empire that the world had ever known and then lost it again. At its greatest extent, the lands they held dwarfed those under the control of Rome at its prime whilst the conquests of its founder, Genghis Khan, outshone those of even Alexander the Great. There were few parts of the known world that were not touched by the Mongols in one way or another: China, India, the Middle East, Europe, Egypt. This was truly a world empire. This is a tale of fiercely fought battles and political intrigue, of unrivalled ferocity and burning ambition. It is a tale not just of military campaigns, though these are of course a vital part of the building of the empire, but also of the many other ways that it grew. The Mongols truly believed that it was their destiny to conquer the world and they came mightily close to doing it. W.B. Bartlett has a longstanding relationship with Mongolia and has used his knowledge of the country and its history to tell this fascinating tale of how a tribe of little known nomads became the most feared warriors that the world has ever seen.
