John Man visits Google's London, UK office to discuss his book "The Leadership Secrets of Genghis Khan." This event took place on April 9, 2009, as part of the [email protected] series. John Man re-examines the life of Genghis Khan to discover the qualities, characteristics and strategies that made him the great leader that he was. The answers are sometimes surprising. Genghis was far from just the tyrant that history records, but rather a leader of exceptional vision and modernity. And many of the secrets of his success are as valuable and applicable in todays competitive business world as they were in rallying the Mongol hordes. John is a historian and travel writer with a special interest in Mongolia and China. He is the author of Alpha Beta on the roots of the Roman alphabet, The Gutenberg Revolution on the origins and impact of printing, the international bestseller Genghis Khan as well as Attila the Hun, Kublai Khan, The Terracotta Army and The Great Wall.
