By the end of 1968, the last vestiges of the radical popular uprising had been suppressed by the PLA, with revolutionary committees finally coming to dominate the country. In its place, Mao Zedong's cult of personality grew to a more totalizing position and the Cleansing the Class Ranks campaign consolidated the power of the Communist Party over China. During the early 1970s, many of the radical changes brought by the Cultural Revolution were rolled back. China–United States relations were normalized, party officials that had been attacked during the revolution were rehabilitated and managerial authority was strengthened, with calls for labor discipline, further rules and regulations, as well as an industrial struggle against the forces of "anarchism" and "ultra-leftism". After the death of Mao Zedong and the end of the first generation of Chinese leadership, Deng Xiaoping established himself as the country's paramount leader and began to repress the leftist elements of the Cultural Revolution, such as the Gang of Four.
