The Hunan–Hubei–Jiangxi Soviet (Chinese: 湘鄂赣苏维埃; pinyin: Xiāng-È-Gàn Sūwéiāi) was a Comintern and local communist-led liberated zone in the 1930s south of the Yangtze River, comprising parts of counties in what are now the municipal regions of Yueyang in Hunan, Xianning in Hubei and, in Jiangxi, Jiujiang and Yichun.
Before the declaration of the CSR in November 1931, the liberated zone had been known to Communists as the Hunan-Hubei-Jiangxi (Xiang-E-Gan) Revolutionary Base Area (湘鄂赣革命根据地).
The Right-Kuomintang (Nationalist) Government intended to destroy the Soviet by means of one of its broadly unsuccessful Encirclement campaigns.
The 16th launched a pre-emptive strike on Tongcheng, in Hubei, in December 1930, annihilating an entire regiment of the KMT army just before it could begin the first attack of the campaign.
As reinforcement troops from other Nationalist Government regions moved in to avenge the defeat at Tongcheng, it was determined at Red Army central command that a diversionary measure was in order.
