The Revolt of the Three Feudatories, () also known as the Rebellion of Wu Sangui, 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. Background In the early years of the Qing Dynasty, during the reign of the Shunzhi Emperor, central government authority was not strong and the rulers were unable to control the provinces in southern China directly. The government initiated a policy of "letting the Han Chinese govern the Han Chinese" (以漢制漢). Some generals of the former Ming Dynasty who had surrendered the Qing were allowed to help govern the provinces in the south. That was the result of the crucial contributions those generals had made at decisive moments during the Qing conquest of China. For instance, the navy of Geng Zhongming and Shang Kexi brought about the quick capitulation of Joseon in 1636, allowing rapid advance into Ming territories without worrying about what was behind. The defection and subsequent cooperation of Wu Sangui allowed swift capture and settlement of the Ming capital Beijing. In return, the Qing government had to reward their achievements, and acknowledge their military and political influence. In 1655, Wu Sangui was granted the title of "Pingxi Prince" (平西王; "West Pacifying Prince") and granted governorship of the provinces of Yunnan and Guizhou. Shang Kexi and Geng Zhongming were granted the titles of "Pingnan Prince" and "Jingnan Prince" (both mean "South Pacifying Prince") respectively, and were put in charge of the provinces of Guangdong and Fujian. The three lords had great influence over their lands and wielded far greater power than any other regional or provincial governors. They had their own military forces and had the authority to alter tax rates in their fiefs. The Three Feudatories In Yunnan
