Ilkhan (title)

• "Tribal Chief". Of note is the use of this lesser meaning as the title for the rulers of Hulagu's state, commonly known as the Ilkhanate. Here the lesser "khanship" intended to indicate the initial deference of Khulagu to Möngke Khan and his successor Great Khans of the Mongol empire. The title "Ilkhan", borne by the descendants of Hulagu and later other Borjigin princes in Persia, does not materialize in the sources until after 1260.
• Khan of the nation. The earliest mention of a similar title in the second meaning, namely "Illig Qaghan", refers to Bumin Qaghan and dates by 552 C.E.
