Guominjun
The Guominjun, also known as the Kuominchun, abbreviated as GMJ and KMC, was a military faction founded by Feng Yuxiang, Hu Jingyi and Sun Yue during China's Warlord Era. The KMC had control of much of Northwest China, including Shaanxi, Chahar and Suiyuan, hence its other name, the Northwest Army.
History
The Guominjun was formed when Feng betrayed the Zhili clique during the Second Zhili–Fengtian War with the Fengtian clique in 1924. The Guominjun occupied Beijing, captured Zhili leader Cao Kun and expelled former Qing dynasty emperor Puyi from the Forbidden City.In late 1925, Fengtian general Guo Songling defected to the KMC; this sparked the Anti-Fengtian War against Zhang Zuolin.
The Guominjun was incorporated into the Kuomintang's National Revolutionary Army as the "Second Collective Army" in 1928 during the Northern Expedition, and fought alongside the KMT to defeat Fengtian forces and capture Beijing.
In 1929, Feng grew increasingly dissatisfied with Chiang Kai-shek's regime; the Guominjun launched a full rebellion with Yan Xishan and Li Zongren’s army, the Central Plains War, in 1930. However, Feng was defeated and what was left of the faction was absorbed into the KMT.
