Genghis Khan (1162-1227) was the founder of the Mongol Empire, which later became the largest contiguous land empire in history 1. He rose from humble beginnings to establish this empire by uniting the nomadic tribes of the Mongolian plateau 2. After uniting these tribes, he conquered huge chunks of central Asia and China 2. His descendants expanded the empire even further, advancing to such far-off places as Poland, Vietnam, Syria and Korea.
