After the communist victory of 1949, Wu De briefly served as Vice Minister of Fuel Industry of the newly established People's Republic of China. He became the Communist Party Chief of Pingyuan Province in 1950, replacing Pan Fusheng, who had been demoted. After Pingyuan Province was abolished in 1952, Wu De was transferred to Tianjin, where he served as Vice Mayor and then Mayor from 1952 to 1955. Afterwards he was appointed the party chief of Jilin Province.
Cultural Revolution
Wu served in this position until the Cultural Revolution started in 1966. As Mao Zedong insisted that the Beijing Municipal Committee needed to be reorganized without Peng Zhen, who contested the policies of the Cultural Revolution, on June 4 the Central Committee transferred Wu De to the capital as second secretary of the CPC Municipal Committee, ranking immediately beneath First SecretaryLi Xuefeng. During their leadership, the two of them ordered the suspension of classes of Beijing universities to allow students to fully concentrate on the Cultural Revolution. In 1967 he became a vice-chairman of the Beijing Revolutionary Committee, and was elected member of the CPC Central Committee in 1969. As Mao Zedong clashed with Lin Biao and Chen Boda at the Central Committee plenum held in Lushan in 1970, Wu De advised him to act swiftly in order to avoid trouble within the People's Liberation Army. He said: "The Chairman must act personally... believing in the possibility to enlighten a lot of people united under the great leader Chairman Mao." From this moment on, Mao praised Wu De, calling him "virtuous". Lin's death in the air crash following his attempted coup in 1971 enforced Wu's position. He was proclaimed head of the Cultural Group Under the State Council, a sort of temporary Minister of Culture. After Xie Fuzhi's death in 1972, Wu De took over as chairman of the Beijing Revolutionary Committee and concurrently first secretary of the CPC Beijing Committee. In 1973 he was admitted into the CPC Politburo. He took active part at the "Criticize Lin Biao, Criticize Confucius" campaign, but Jiang Qing, believing he wanted to mislead the movement, criticized him, bringing forth his hostility towards the Gang of Four. In 1975, he was a vice-chairman of the Standing Committee of the National People's Congress. Wu De actively struggled against a rehabilitated Deng Xiaoping and worked to promote Hua Guofeng as Mao's successor. He advocated repression of the 1976 Tiananmen Incident, earning the ironic nickname of "no virtue". In October of the same year, he played a role in the arrest of the Gang of Four.
Downfall under Deng Xiaoping
The rise of Deng Xiaoping and the ouster of the Gang of Four marked the beginning of a repudiation of the Cultural Revolution. Though initially an important part of Hua Guofeng's leadership, Wu De was openly criticized at the Third Plenary Session of the 11th CPC Central Committee and lost his Politburo seat. In 1980, along with Chen Xilian and other Maoists, he was purged and resigned his post in the NPC Standing Committee. Despite his participation to the Cultural Revolution, his role in removing the Gang of Four earned him a powerless position in the Central Advisory Commission. He died in Beijing in 1995.
