Guominjun in the context of Warlord era

Feng Yuxiang (simplified Chinese: 冯玉祥; traditional Chinese: 馮玉祥; pinyin: Féng Yùxiáng; IPA: [fə́ŋ ỳɕi̯ɑ́ŋ]; 6 November 1882 – 1 September 1948), courtesy name Huanzhang (焕章), was a Chinese warlord and later general in the National Revolutionary Army. He served as Vice Premier of China from 1928 to 1930.

At the start of the 1911 Revolution, Feng was an officer in the ranks of Yuan Shikai's Beiyang Army. He initially joined forces with the revolutionaries, but came to support Yuan's regime. In 1914, he converted to Christianity, earning him the nickname the "Christian General". He became a warlord in Northwest China, based in Shaanxi, and rose to a high rank within the Zhili clique, a powerful warlord faction. In 1924, during the Second Zhili-Fengtian war, Feng launched the Beijing Coup, which knocked the Zhili out of power, and re-organised his troops as the Guominjun. He brought Sun Yat-sen to Beijing for negotiations on re-unification, but this was not realized. In 1926, Feng was defeated by the Zhili and Fengtian cliques in the Anti-Fengtian War, and he retreated to the northwest. In 1926, Feng joined the Kuomintang's successful Northern Expedition. He later resisted Chiang's consolidation of power in the Central Plains War and was forced to retire, but in 1933 organized a new army which successfully drove the Japanese Army out of Chahar. In the 1930s, Feng held positions in the Nationalist government, including brief army commands at the start of the Second Sino-Japanese War in 1937. He spent his later years supporting the anti-Chiang Revolutionary Committee of the Kuomintang before his death in 1948.

The Anti-Fengtian War (Chinese: 反奉战争; pinyin: Fǎnfèng zhànzhēng) was the last major civil war within the Republic of China's northern Beiyang government prior to the Northern Expedition. It lasted from November 1925 to April 1926 and was waged by the Guominjun against the Fengtian clique and their Zhili clique allies. The war ended with the defeat of the Guominjun and the end of the provisional executive government. The war is also known as either Guominjun-Fengtian War (Guófèng zhànzhēng, 国奉战争), or the Third Zhili–Fengtian War (Dì sān cì zhífèng zhànzhēng, 第三次直奉战争).
