In 740, his mother Sebeg Khatun and grand vizier Yusi Tarkhan conspired together to centralize the state and kill the cousins of Kutluk Tengri Qaghan who were ruling as governors in the west and the east. They wanted child Kutluk Tengri as khagan so they can rule the state how they want. They was afraid of elder princes of Göktürks will rebel against Kutluk Tengri to be khagan. While they succeeded killing the western governor prince, the eastern governor prince Pan Kul Tegin rebelled and marched on the capital Ordu Balıq. He captured Kutluk Tengri Qaghan and executed him, causing his mother and regent Sebeg Khatun to flee. Pan Kul Tegin should not to be confused with Kul-Tigin.
