Before Balasagun  Kashgar was the capitol of the Kara khanid confederation. It was populated primarily by Karluk who were part of the Kara khanid confederation. Of course the Kara Khanids were vassal to the Turkmen Seljuk.

By 1934 Kashgar was majority Uygur.  There was a significant Hui Hui minority and when the British tried to steal West China the Hui Hui who in the west were called Tongans or Dongans sacked the British Consulate killing many of the British provocateurs.
