In short: In 1926, the Kuomintang launched the Northern Expedition to dismantle the warlord-dominated Beiyang government. This ambitious military drive aimed to unify a fragmented nation, but it triggered a violent internal collapse, pitting former communist allies against nationalist leaders in a struggle that reshaped the future of the Chinese state.

The Northern Expedition began in July 1926 under Generalissimo Chiang Kai-shek, who commanded the National Revolutionary Army. The campaign sought to end the rule of regional warlords who had controlled China since the 1911 Revolution. Initially, the Kuomintang operated as a fragile coalition, relying on Soviet advisors like Mikhail Borodin and Vasily Blyukher to modernize their military and political strategy. By targeting warlords like Wu Peifu and Sun Chuanfang, the nationalist forces expanded their reach across seven provinces, eventually controlling a population of roughly 170 million people by early 1927.

The expedition’s momentum stalled due to deep ideological rifts. The First United Front, which had united the Kuomintang with the Chinese Communist Party, disintegrated as tensions over influence and foreign policy peaked. Following the capture of Shanghai and Nanjing in March 1927, Chiang Kai-shek launched a violent purge of communists in April, effectively splitting the nationalist movement between his right-leaning faction in Nanjing and the left-leaning government in Wuhan. This internal conflict forced a temporary halt to the northern advance, as both factions vied for control and legitimacy.

Chiang resumed command in January 1928, launching the second phase of the campaign. By aligning with powerful warlords such as Yan Xishan and Feng Yuxiang, the nationalist forces pushed toward the Yellow River and eventually Beijing. The collapse of the Fengtian clique, led by Zhang Zuolin and later his son Zhang Xueliang, signaled the end of the Beiyang government. In December 1928, Manchuria pledged its allegiance to the nationalist government in Nanjing. This final consolidation marked the successful conclusion of the Northern Expedition and the beginning of the Nanjing decade, establishing the Kuomintang as the primary authority in China.
