Khan was the name given to male rulers of the Mongols, Tartars, or Turkic/Altaic peoples of Central Asia, with female rulers called khatun or khanum. Though the term seems to have originated with the Turkic peoples of the high inner steppes, it spread to Pakistan, India, Afghanistan and Persia through the expansion of the Mongols and other tribes.
