Qu Qiubai (1899-1935), a native of Changzhou, Jiangsu Province, joined the Communist Party of China in 1922 and was one of the leaders of the Party in its early years. In 1927, at the crucial juncture after the failure of the Great Revolution (1924-27), he and Li Weihan presided over the ``August 7th'' emergency meeting of the Central Committee. After this he took charge of the day-to-day work of the central leading body as a Standing Committee member of the Political Bureau of the Party's Provisional Central Committee. Qu committed the error of ``Left'' putschism in the period from November 1927 to April 1928. In September 1930, he presided over the Third Plenary Session of the Sixth CPC Central Committee, which put an end to Li Lisan's ``Left'' adventurist mistakes. Later, at the Fourth Plenary Session of the Sixth CPC Central Committee held in 1931, he was attacked by the dogmatists and sectarians under the influence of Wang Ming's ``Left'' line, and was pushed out of the central leading body of the Party. Arrested by the Kuomintang in February 1935 on his way from Jiangxi to Fujian, Qu Qiubai died a martyr's death in Changting, Fujian, on June 18 of that year. During the ``cultural revolution'' he was slandered as a ``renegade''. The Central Committee restored his good name in October 1980.
