The Revolt of the Three Feudatories was a rebellion in China lasting from 1673 to 1681, during the early reign of the Kangxi Emperor (r. 1661–1722) of the Qing dynasty (1644–1912). The revolt was led by the three lords of the fiefdoms in Yunnan, Guangdong and Fujian provinces against the Qing central government. These hereditary titles had been given to prominent Han Chinese defectors who had helped the Manchu conquer China during the transition from Ming to Qing. The feudatories were supported by Zheng Jing's Kingdom of Tungning in Taiwan, which sent forces to invade Mainland China. Additionally, minor Han military figures, such as Wang Fuchen and the Chahar Mongols, also revolted against Qing rule. After the last remaining Han resistance had been put down, the former princely titles were abolished.
