Genghis Khan (1162? to 1227): Mongol conqueror, born in Temujin. He succeeded his father at 13, and struggled for many years against hostile tribes, subjugating the Naimans, conquering Tangut, and receiving the submission of the Turkish Uigurs. In 1206 he changed his name to the one by which he is now known, which translates as “universal ruler.” By his death the Mongol empire stretched from the Black Sea to the Pacific. He launched the only successful winter invasion of Russia in history.
