Xianbei confederation for their chief between 283 and 289. The
Rourans were the first people who used the titles
khagan and
khan for their emperors, replacing the
Chanyu of the
Xiongnu, whom Grousset and others assume to be
Turkic. Subsequently the
Ashina adopted the title before the Mongols brought it to the rest of Asia. In the middle of the sixth century the
Iranians knew of a "Kagan – King of the Turks".
