Hu Hanmin
In 1931, Hu Hanmin attempted to block Chiang's provisional constitution and was put under house arrest. This caused another uprising by Chen Jitang, Li Zongren, Sun Fo and other anti-Chiang factions who converged on Guangzhou to set up a rival government. War was averted due to the Japanese invasion of Manchuria but it did cause Chiang to release Hu and resign as president and premier. Chiang's influence was restored when he was made chairman of the Military Affairs Commission at the start of the Battle of Shanghai (1932). Hu moved to Guangzhou and led an autonomous government in Liangguang.
