中央文化革命小组
Concerned that the group was stifling the development of the Cultural Revolution, Mao engineered the dissolution of the Five Man Group in the May 16th Circular. The same document condemned Peng Zhen for obstructing the Cultural Revolution, and replaced the group with the Cultural Revolution Group, an organisation of Maoist supporters that would bring a significantly more radical thrust to the Cultural Revolution. 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.
