Cause

Following the end of the Northern Expedition in 1928, a demilitarization conference in 1929 strained relations between Chiang Kai-shek's Nanjing government and several regional warlords. Yan Xishan, Feng Yuxiang, Li Zongren, and Zhang Fakui broke with Chiang and formed an anti-Chiang coalition, openly contesting the legitimacy of the Nanjing government.

Event

The Central Plains War was a series of military campaigns fought across Henan, Shandong, Anhui, and adjoining areas of the Central Plains. The Nationalist Kuomintang government in Nanjing, led by Chiang Kai-shek with roughly 300,000 troops, faced a coalition of former allies commanding approximately 700,000 soldiers in the largest conflict of the Warlord Era.

Consequence

The war ultimately tested and affirmed the relative military authority of Chiang Kai-shek's Nanjing government against the warlord coalition, though the prolonged fighting across multiple provinces underscored the fragility of Chinese national unification achieved after the Northern Expedition and the persistent challenge of regional military power.
