The Fifth Encirclement Campaign against Jiangxi Soviet was a series of battles fought during the Chinese Civil War from September 25, 1933 to October 1934 between Chiang Kai-shek's Kuomintang (nationalist) and the Chinese communists. During this campaign, the Kuomintang successfully overran the communist Chinese Soviet Republic and forced the communists on the run, an event later known as the Long March. Chiang Kai-shek and the Kuomintang called this campaign the Fifth Encirclement Campaign () at the time, while the Chinese communists call it the Fifth Counter Encirclement Campaign at the Central Soviet (), also known as the Fifth Counter-Encirclement Campaign at the Central Revolutionary Base () or Fifth Extermination Campaign.
