The Rebellion of Nine-Oguzs and the Death of Khan Kapagan (716)     

        But the kingdom was boiling like a boiler. The conditions can be understood from the words written in the inscriptions, such as "when my khan uncle's administration is under the disorder, and there is duality between the people…". The Azs and then İzgis were severely defeated (715). But, the rebellion of Oguzs resulted in the big wounds in the social structure of Gok-Turks, since Oguzs were constituted the basic group of the kingdom; so their rebellion shocked the state fundamentally. And the biggest consequence of the rebellion was the independence of the west )the country of On-oks, namely Karluks, Turgişs and Transoxiana).

 

        It can be perceived from the inscriptions that the rebellion of Oguzs which began in the autumn of the year of 714 -for the relationship of Oguzs with the state- was received with surprise. " -Nine-Oguz clan was my clan, because of the disorder of the sky and the land, it became enemy". In the spring of 715, the animals of Oguzs, who were defeated during the Khan's Nine-Oguzs attack. In the year of 716, the Bayirkus from the clan of Oguzs were severely repressed. However, this was the last one of the victories of Khan Kapagan, who had a bad-tempered nature. He was trapped by Bayirkus while he was turning back to Ötüken sure of himself, and he was killed by one of Bayirkus who jumped upon Khan (716, July 22). Bayirkus' relations with China can be understood from the presence of a Chinese envoy at that time. According to a rumour, the Kapagan's head was cut and brought to China by this envoy.
