Background

He was the second son of the fourth ruler, Bilge Khagan, and was preceded by his elder brother Yollig Khagan. Tengri was a minor and dominated by his mother Po Beg.

Reign

In 740, Xuanzong sent his envoy Li Zhi (李質) who declared him Tengri Khagan.^[2] His mother El Bilge Khatun and chancellor Yusi Tarkhan (飫斯達幹)^[3] conspired together to centralize the state and kill the cousins who were ruling as governors in the west and the east. While they succeeded in killing the western shad, the eastern shad Pan Kul Tigin rebelled and marched on the capital. He captured Tengri and executed him, causing his mother and regent El Bilge Khatun to flee.

After death

Pan Kul Tigin crowned his son Ozmish as Khagan in 741 and himself as regent. However, he was quickly defeated and executed by Ashina Shi (阿史那施) who marched to the capital and executed both Kutluk Yabghu and Ozmish, declaring himself as Khagan.
