Emerging out of the vast steppe grasslands of Central Asia in the early 1200s, the Mongols, under their ferocious leader, Genghis Khan, quickly carved out an empire that by the late thirteenth century covered almost one-sixth of the Earth's landmass—from Eastern Europe to the eastern shore of Asia—and encompassed 110 million people. Far larger than the much more famous domains of Alexander the Great and ancient Rome, it has since been surpassed in overall size and reach only by the British Empire.
