Genghis Khan alias Temüjin

Genghis Khan was the official title of a Mongol warrior named Temujin, a 13th century ruler who founded an empire that included parts of China, Central Asia, the Middle East and Europe. After a childhood of violence and enslavement, Temujin became a powerful tribal chieftan. By 1206 he had unified rival clans and taken the title Genghis Khan (or Chinggis Khan), meaning "universal ruler."
“He was a cruel man but he led our country to greatness,” said Toguldur Munkochir, 25, a bank teller unwinding at the Chinggis Khaan bar later that night. “If you look at Hitler and Julius Caesar, it’s kind of the same thing.”
