"...Large numbers of Sogdian refugees came to Ordu Baliq (Karabalghasun) to escape the Islamic conquest of their homeland. They converted the Uyghur nobility from Buddhism to Manichaeism. Thus, the Uyghurs inherited the legacy of Sogdian Culture. Sogdians ran the civil administration of the empire. They were helpful in outflanking the Chinese diplomatic policies which had destabilized the Göktürk Khaganate. In AD 840, following a famine and civil war, the Uyghur Khaganate was overrun by the Kirghiz, another Turkic people. As a result the majority of tribal groups formerly under Uyghur control migrated to what is now northwestern China, especially to the modern Xinjiang Uyghur Autonomous region.".....http://en.wikipedia.org/wiki/History_of_the_Uyghur_people
