Tensions between Hui and Uyghurs arose because Hui troops and officials often dominated the Uyghurs and crushed Uyghur revolts.[146] Xinjiang's Hui population increased by over 520 per cent between 1940 and 1982, an average annual growth of 4.4 per cent, while the Uyghur population only grew at 1.7 per cent. This dramatic increase in Hui population led inevitably to significant tensions between the Hui and Uyghur populations.
