Even at an abstract theoretical level, the power configuration in China after the 1969 9th Party Congress was highly unstable. On the one hand, Mao continued to be an active and powerful chairman of the party. On the other hand, Lin Biao, the anointed successor, had a great deal of control over the military. Without the possibility of other powerful factions in the party to check a potential fight between Mao and Lin, both sides had much temptation to eliminate the other if they believed they had sufficient power to do so (Acemoglu et al. 2008: 162). Fortunately for Mao, he had cultivated two disparate groups to help him govern China in the event of a purge of Lin Biao: the Fourth Front Army (FFA) and the surviving scribblers. Mao’s strategy of cultivating the tainted FFA paid off handsomely. Instead of having to concede to Lin Biao’s reluctance to carry out self-criticism or being forced to rely on Lin’s followers, Mao forced Lin’s hand, knowing that he could credibly threaten Lin with replacing the Lin Biao faction with FFA veterans. After Lin Biao fled, Mao carried out his threat and eradicated close associates of Lin Biao wholesale from the military, replacing them with veterans of the FFA. The Lin Biao incident on September 13, 1971, finally led to the full installation of the coalition of the weak.

Zhang Chunqiao helped Mao launch the Cultural Revolution and became a core member of the Central Cultural Revolution Group (CCRG). At the 10th Party Congress in 1973, Mao promoted him into the most powerful institution in the Chinese Communist Party, the Politburo Standing Committee, a rarely seen leap for a pre–Cultural Revolution vice-provincial-level official in the space of seven years. When his daughter asked him right after the congress whether he felt a sense of triumph, Zhang responded, “I don’t feel much. Which revolutionary base area did I build? Which army did I lead? Which battle did I win?” (Zheng 2017: ix) Despite his formal power, Zhang knew that since he was a writer and an ideologue instead of someone with faction followers throughout the party and the military, he had very little informal power. Given their limited political experience and narrow political networks in the party, why did Mao elevate Zhang and others in the scribblers mafia (笔杆子) into senior offices during the Cultural Revolution?
