陈独秀对共产国际将大革命失败的责任推到他身上的做法极其不满,继而接受托洛茨基的观点,加入托派。在随后的中东路事件中,他反对中共中央提出的“保卫苏联”的口号,与中共中央进行了反复的辩论,最后被开除出党。本文根据共产国际档案文献,对共产国际与陈独秀被开除出党的前后历史作一初步考察。 Chen Duxiu was extremely unhappy about the Communist International’s responsibility to push the failure of the Great Revolution to him, and accepted Trotsky’s point of view and joined the Trotskyites. In the ensuing Middle East incident, he opposed the slogan of “defending the Soviet Union” put forward by the CPC Central Committee, held repeated debates with the Central Committee of the Communist Party of China, and was eventually expelled from the party. Based on the archives of the Communist International, this article makes a preliminary study of the history before and after Comvind and Chen Duxiu were expelled from the party.
