Chen Duxiu (simplified Chinese: 陈独秀; traditional Chinese: 陳獨秀; pinyin: Chén Dúxiù; Wade–Giles: Chʻên Tu-hsiu; 9 October 1879 – 27 May 1942) was a Chinese revolutionary, writer, educator, and political philosopher who co-founded the Chinese Communist Party (CCP) with Li Dazhao in 1921, serving as its first General Secretary from 1921 to 1927. Chen was a leading figure in the New Culture Movement and May Fourth Movement of 1919, which significantly influenced China's intellectual and political landscape in the early 20th century.
Born in Anhui, Chen was raised in a traditional gentry family but became involved in revolutionary activities from a young age. He studied in Japan, where he was exposed to Western ideas and became involved with Chinese student activist groups. Returning to China, he played a key role in local revolutionary movements in Anhui, notably through journalism and education, advocating for a vernacular literary revolution and the preservation of China's "national essence". During the New Culture Movement (c. 1915–1922), Chen rose to national prominence as the editor of the influential magazine New Youth (Xin Qingnian) and as Dean of Arts and Letters at Peking University. He championed science, democracy, and vernacular literature, while launching trenchant critiques of traditional Confucianism and Chinese society. His writings and leadership were instrumental in shaping the May Fourth generation of intellectuals and activists.
