After coming to power in 744, Kutlug Bilge Khagan moved his court to Khar Balgas (Ordu-Baliq) in the Orkhon valley.
For the next two years, the Uighur power continuously expanded, although its control did not reach the size of the Turkic Khaganate.
Nine tribes included Dokuz Oghuz (nine Oghuz tribes), which were the Khaganal clan/sub-tribe Yaglakar (simplified Chinese: 药罗葛; traditional Chinese: 藥羅葛; pinyin: Yàoluógé) and eight Uighur clans/sub-tribes known in Chinese rendering: According to Edwin Pulleybank six Tiele tribes in the confederation - Bugu (僕固), Hun (渾), Bayegu (拔野古), Tongluo (同羅), Sijie (思結) and Qibi (契苾) had an equal status with the Uighurs (迴紇); the reduced Basmyls numbered eight sub-tribes, and Karluks had three sub-tribes, thus the collective appellation Üç-Karluk (Three Karluks).
Basmyls and Karluks were defeated by the Jiu Xing and forcibly incorporated, had a lower status, and were staged as vanguard of the Uighur army, thus bringing the total number of tribes to eleven.
[9] In contrast, Golden (1992) proposed that Toquz Oğuz consisted of Uygur-led group comprising nine tribes: Bugu, Hun, Bayegu, Tongluo, Sijie, Qibi, A-Busi, Gulunwugusi and the Uyghur proper, which comprised the nine clans of Yaglakar, Huduoge, Guluowu, Mogexiqi, AWudi, Gesa, Huwasu, Yaowuge, and Xiyawu.
