an lushan (安祿山) or kang yaluoshan (康軋犖山) or ܪܘܚܫܐܢ (roxsan) in sogdian or göktütk was a general and military governor in the tang army, and he rebelled against the tang and formed his own yan dynasty. millions of tang chinese died in the rebellion. after 6.9 years his dynasty collapsed, and tang regained control. after that no chinese dynasties trusted nor promoted any officials and generals of göktürk or turkic descent to high office. and turkic cultural influence died at the uyghur border as ironically the uyghur khaganate assisted the tang in putting down the göktürk rebellion. even the abbasid caliphate allied with the tang to eliminate the göktürk threat in central asia. it would be almost impossible for turks to stage a cumback in tiongcock as there’s more than a thousand years of animosity and vengeance.
