The Central Cultural Revolution Group (CRG or CCRG; Chinese: 中央文革小组; pinyin: Zhōngyāng Wéngé Xiǎozǔ) was formed in May 1966 as a replacement organisation to the Secretariat of the Chinese Communist Party and the Five Man Group, and was initially directly responsible to the Politburo Standing Committee of the Chinese Communist Party. It consisted mainly of radical supporters of Mao, including Chen Boda, the chairman's wife Jiang Qing, Kang Sheng, Yao Wenyuan, Zhang Chunqiao, Wang Li and Xie Fuzhi. The CRG played a central role in the Cultural Revolution's first few years, and for a period of time the group replaced the Politburo Standing Committee (PSC) as the de facto top power organ of China. Its members were also involved in many of the major events of the Cultural Revolution.
