Chiang Kai-shek National Revolutionary Army Northern Expedition Sun Yat-sen
When party leader Sun Yat-sen died in May 1925, he was succeeded by Chiang Kai-shek, who moved to marginalise the left-KMT and the Communists. Mao nevertheless supported Chiang's National Revolutionary Army, who embarked on the Northern Expedition attack in 1926 on warlords. In the wake of this expedition, peasants rose up, appropriating the land of the wealthy landowners, who were in many cases killed. Such uprisings angered senior KMT figures, who were themselves landowners, emphasising the growing class and ideological divide within the revolutionary movement.
