Genghis Khan is considered the world's greatest conquerer. Why was he so successful? In this talk to his Chinese high school students, Jiang Xueqin argues that Genghis Khan had the same characteristics as other great conquerors, such as Sargon of Akkad, Philip of Macedon, and Julius Caesar. Genghis Khan believed that he had a divine mission to re-make the world. In overcoming hardship and defeat, Genghis Khan came to recognize his mission, and committed himself to completing it. He united the warring Mongol tribes into a professional, meritocratic, and innovative army that would go on to conquer most of the Asian continent.
