Bayanchur Khan

His Tang dynasty invested title was Yingwu Weiyuan Pijia Qaghan[1] (Chinese: 英武威遠毗伽闕可汗; lit.

[5] At time of his birth, clan chief Yaoluoge Dujiezhi (藥羅葛獨解支) had recently moved near the Tang border, avoiding expansion of the Second Turkic Qaghanate.

As a result, Wang Junchuo did not dare to counterattack, and subsequently blamed the defeat on a number of tribal chiefs in the area and had them exiled.

Emperor Suzong of Tang appealed to Bayanchur in 756 for help against An Lushan, sending his second cousin Li Chengcai (李承寀) the Prince of Dunhuang and Pugu Huai'en as emissaries.

Uyghur forces led by Uyghur Prince Ulu Bilge Yabgu and general Dide arrived at Emperor Suzong's then-headquarters at Fengxiang (鳳翔, in modern Baoji) to join the elite Tang forces recalled from the Anxi Circuit and the Western Regions (Xiyu).

Chinese chancellor Li Mi suggested that these forces be used to attack An Lushan's power base at Fanyang first, to root out the possibility of a recovery.

[2] Bayanchur was married to a Uyghur who was created El Bilge Khatun (Old Turkic: 𐰠𐰋𐰠𐰏𐰀𐰴𐱃𐰆𐰣) in 747 and Princess Xiaoguo (蕭公主) on 25 August 758, daughter of Suzong.
