This pocket biography examines the life of the 13th-century emperor, Genghis Khan, infamous for his bloodthirsty, ruthless campaigns, but also one of the great commanders of history. Khan sought to become the ruler of all Mongol peoples. He began the conquest of China in 1213 and invaded India, while his subordinates took land as far as Crimea. When he died in 1227, his empire ranged from the Caspian Sea to northern China.
