The 6th National Congress
Date: June 18-July 11, 1928
Number of delegates: 84 (plus 34 alternate delegates)
Party membership: More than 40,000
Major contents: The major tasks of the congress were to sum up the experiences learnt after the failure of the First Great Revolution (June 1923-July 1927), analyze the nature of the revolution and the political situation, work out the lines, guiding principles and policies of the Party during a new period, to unite the whole Party in thought and develop revolutionary forces. The congress affirmed that Chinese society remained in nature a semi-colonial and semi-feudal society, and that the "Chinese revolution at the present stage is by nature a bourgeois democratic revolution". It formulated 10 programs of the democratic revolution. It pointed out that the political situation in China at that time was one between two revolutionary high tides, and that the general task of the Party was, therefore, not to attack and organize uprisings but to win over the masses and prepare for insurrections. The congress criticized both "Right" and "Left" opportunism, especially putschist mistakes.
The congress elected the Sixth Central Committee composed of 23 members and 13 alternate members, which elected Xiang Zhongfa, Zhou Enlai, Su Zhaozheng, Xiang Ying, Qu Qiubai, Zhang Guotao and Cai Hesen into its Political Bureau, with Xiang Zhongfa serving as the general secretary.
