六胡州的变迁与六州胡的种族

至德元年（７５６年），六胡州受安史叛军招诱东出投奔叛军，被以原经略军的建制安置在范阳。由于这种变故，唐在宝应（７６２—７６３年）后废除宥州。贞元二年（７８６年）六州胡从石州被迁往云、朔。元和九年唐复置宥州经略军，居民却是神策军行营兵士及家属。至于迁往云、朔的六胡州，由于沙陀东迁进入其中之故，六胡州内已是沙陀与六州残胡杂处，且六州胡处干沙陀押领之下。六胡州是唐为管理突厥降户中的中亚昭武九姓而设置，其居民六州胡主体是昭武九姓，且是昭武九姓中柘羯类

Abstract In the first year of Zhide period (756A.D.) the Liuhu (six barbarians) were populated in Fanyang when they went for shelter to the rebel army led by An Lushan and Shi Siming. Later they were moved to Yun and Shuo prefectures and lived together with the Shatuo and other barbarians. The Liuhu prefecture was set up by the Tang government in order to control the nine clans of Zhao and Wu coming from the Central Asia.
