The Central Plains War was a series of military campaigns in 1929 and 1930 that constituted a Chinese civil war between the Nationalist Kuomintang government in Nanjing led by Generalissimo Chiang Kai-shek and several regional military commanders and warlords who were former allies of Chiang.

Feng Yuxiang, courtesy name Huanzhang (焕章), was a Chinese warlord and a leader of the Republic of China from Chaohu, Anhui. He served as Vice Premier of the Republic of China from 1928 to 1930. He was also known as the "Christian General" for his zeal to convert his troops and the "Traitorous General" for his penchant to break with the establishment. In 1911 he was an officer in the ranks of Yuan Shikai's Beiyang Army but joined forces with revolutionaries against the Qing dynasty. He rose to high rank within Wu Peifu's Zhili warlord faction but launched the Beijing Coup in 1924 that knocked Zhili out of power and brought Sun Yat-sen to Beijing. He joined the Nationalist Party (KMT), supported the Northern Expedition and became blood brothers with Chiang Kai-shek, but resisted Chiang's consolidation of power in the Central Plains War and broke with him again in resisting Japanese incursions in 1933. He spent his later years supporting the Revolutionary Committee of the Kuomintang.
