Taiping Rebellion, 1850-64, revolt against the Ch'ing (Manchu) dynasty of China. Perhaps the most important event in 19th-century China, it was led by Hung Hsiu-ch'üan, a visionary from Guangdong who evolved a political creed influenced by elements of Christianity. His object was to found a new dynasty, the Taiping [great peace]. Strong discontent with the Chinese government brought him many adherents, especially among the poorer classes, and the movement spread with great violence through the eastern valley of the Chang River. The rebels captured Nanjing in 1853 and made it their capital. The Western powers, who at first sympathized with the movement, soon realized that the Ch'ing dynasty might collapse and with it foreign trade. They offered military help and led the Ever-Victorious Army, which protected Shanghai from the Taipings. The Taipings, weakened by strategic blunders and internal dissension, were finally defeated by new provincial armies led by Tseng Kuo-fan and Li Hung-chang.
