Fourth Qaghan of the Second Turkic Khaganate

Bilge Qaghan (; ; 683 – 25 November 734) was the fourth Qaghan of the Second Turkic Khaganate. His accomplishments were described in the Orkhon inscriptions.

As was the custom, his personal name and the name after assuming the title Qaghan were different. His personal name was recorded in Chinese characters as 阿史那默棘連 His name after assuming the title was Bilgä Qaγan. (,

In 716, Qapaghan Qaghan, the second Qaghan, was killed in his campaign against the Toquz Oghuz alliance and his severed head was sent to Chang'an. Although his son Inel Khagan succeeded him, Bilgä's brother Kul Tigin and Tonyukuk carried out a coup d'état against Inel Qaghan. They killed him and made him Bilgä Qaghan.

In 720, Wang believed that the Pugu (僕固) and Xiedie tribes of the region were planning to defect to Eastern Tujue and attack with Eastern Tujue troops. He thus held a feast and invited the chieftains, and, at the feast, massacred them. He then attacked the Pugu and Xiedie tribes in the area, nearly wiping them out. He then proposed a plan to attack Qaghan along with the Baximi, Xi, and Khitan. In 733, he defeated rebellious Khitan tribes. He did not die immediately and he had time to punish the family of Buyruk Chor with death. He died on 25 November 734, his burial ceremony took place on 22 June 735.

After his death from poisoning, several steles were erected in the capital area by the Orkhon River. These Orkhon inscriptions are the first known texts in the Old Turkic language.

Bilge Qaghan is portrayed by Kang Jae ik in the 2006 2007 KBS TV series Dae Jo yeong.
