The Karluk Yabghu () was a polity ruled by Karluk tribes, estimated to have existed between the 5th-8th centuries CE.
The first information about the tribes of Karluks that occupied the territory between Altai and the Eastern coast of Lake Balkhash dates back to the 5th century. The Karluks were part of the First Turkic and Uyghur khaganates. Karluk leaders held the title Kül-Erkin as vassals of Göktürks, a rank of medium importance in the First Turkic Khaganate.
They were composed of three tribes, therefore their ruler was mostly called ÃÂç Karluk Bey () in the 8th century (Although Bey and Yabghu are different.). At least one Kül Erkin held the title Yabghu while still acknowledging the suzerainty of Gokturk Khagan.
In 742, they were named "Saã Yabghu ( ð°Âð°Âð°Âð°Âð°Âð° ð°½ð°Âð°Â, tr. Right Yabghu) " by Basmyl khagan Ashina Shi. Like Basmyls, they were ruled by a branch of the Ashina tribe. However, the reign of Basmyl was cut short when they were defeated by a Karluk-Uyghur coalition. Uyghur Khagan gave the Saã Yabghu a new and higher title: 'Sol Yabghu (ð°½ð°Âð° ð°Âð°Âð°Âð°Âð°Âð°Â, tr. Left Yabghu)'.
At the same time a group of Karluks elected Bilge Yabghu Tun Apa Yigen Chor (Old Turkic:ð°Âð°Âð°Âð°Âð° ð°Âð°Âð°Âð°Âð°Âð° ð±Âð°Âð°£ ð°Âð°¯ð° ð°Âð°Âð°Âð° ð°£ ð°Âð°Âð°Âð°º; Bilgä Yabãu Toà Âa Apa Yigen ÃÂor, ) who submitted to the Uyghur Khaganate in 746. He may be same person as Yigen Chor (ð°Âð°Âð°Âð°¤ð°²ð°Âð°º) mentioned in Kul-Chor stele.
He was succeeded by Tun Bilge Yabghu () in 753. A ruler of Karluks were mentioned in Turco-Manichean book "Sacred Book of Two Fundamentals" (Iki Jïltïz Nom), fragments of which were found in 1907 at Kara-Khoja in the Turpan oasis by Albert von Le Coq. The book was dedicated to the ruler of the Chigil tribes, named Alp Burguchan, Alp Tarhan, Alp ðl Tirgüg. He probably was the one who conquered Turgesh state and resettled Karluks in Zhetysu basin, making Suyab their capital.
Another ruler was Köbäk, whose coins were found in modern Kyrgyzstan. He used the title 'Khagan' in his coins.
When the Yenisei Kyrgyz destroyed the Uyghur Khaganate in 840, Karluk yabghu declared himself khagan with title Bilge Kul Qadir Khan, forming the Kara-Khanid Khanate.
The Anikova dish is a Nestorian Christian plate with decoration of a besieged Jericho, by Sogdian artists under Karluk dominion, in Semirechye. It is dated to the 8th century, of which an ast silver of the 9th-10th century is known, copied from an original.
