聯俄容共
In March 1927, Mao Zedong appeared at the Third Plenum of the KMT Central Executive Committee in Wuhan, which sought to strip General Chiang of his power by appointing Wang Jingwei leader. The first phase of the Northern Expedition was interrupted by the political split in the Kuomintang following the formation of the Nanjing faction in April 1927 against the existing faction in Wuhan. Members of the Chinese Communist Party, who had survived the April 12 massacre, met at Wuhan and reelected Chen Duxiu (Ch'en Tu-hsiu) as the Party's Secretary General. The split was partially motivated by the purge of the Communists within the party, which marked the end of the First United Front, and Chiang Kai-shek briefly stepped down as the commander of the National Revolutionary Army.
