Kul

Kültigin (Prince Kül) was the brother of Bilge Khan and co-administrator of the Kokturk empire.

He was killed in a war against a branch of Oguz Turks (a tribe of Turkic people that gave way to the establishment of Seljuks and Ottoman Empire several centuries later) on 732 AD. His life story and advices on state administration are carved on one of the monuments named as Orhon inscriptions.
