From January to November 1965, the Five Man Group was essentially dormant, playing little part in the events that were to precede the
Cultural Revolution. However, the publication of
Yao Wenyuan's criticism of Wu Han's play
Hai Rui Dismissed From Office spurred the group into action. and Yao's failure to do this displeased Peng. He was not prepared to allow the academic criticism of Wu Han's play to develop into a political debate, and so he moved to block the distribution of Yao Wenyuan's politically motivated article. In the subsequent months, Peng and his supporters were dismissed from their offices, with the mayor of Beijing becoming the first major casualty of the movement. Lu Dingyi, the head of the party's propaganda department, was also purged. ==Notes==
