Jiuquan, formerly known as Suzhou, is a prefecture-level city in the northwesternmost part of Gansu Province in the People's Republic of China.

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.
