It may also be translated as "Khan of Khans", equivalent to King of Kings. In Bulgarian, the designation became requested as "Khan" as in the "Nominalia of the Bulgarian Khans," Именник на българските ханове, while in innovative Turkic, the names became Khaan with the "g" sound becoming nearly silent or non-existent i.e. a very light voiceless velar fricative; the ğ in modern Turkish Kağan is also silent. Since the division of the Mongol Empire, monarchs of the Yuan dynasty and the Northern Yuan held the title of Khagan. Kağan, Hakan and Kaan, Turkish equivalents of the title are common Turkish names in Turkey.
The common western rendering as Great Khan or Grand Khan, notably in the issue of the Mongol Empire, is a translation of Yekhe Khagan Great Emperor or Их Хаан.
