The Dungan Revolt (1862–1877), also known as the Tongzhi Hui Revolt or Hui (Muslim) Minorities War, was a war fought in 19th-century western China, mostly during the reign of the Tongzhi Emperor of the Qing dynasty. The term sometimes includes the Panthay Rebellion in Yunnan, which occurred during the same period. However, this article refers specifically to two waves of uprising by various Chinese Muslims, mostly Hui people, in Shaanxi, Gansu and Ningxia provinces in the first wave, and then in Xinjiang in the second wave, between 1862 and 1877. The uprising was eventually suppressed by Qing forces led by Zuo Zongtang.

Dungan is a Sinitic language spoken primarily in Kazakhstan, Russia and Kyrgyzstan by the Dungan people, an ethnic group related to the Hui people of China. Although it is derived from the Central Plains Mandarin of Gansu and Shaanxi, it is written in Cyrillic and contains loanwords and archaisms not found in other modern varieties of Mandarin.
