The military modernization program of the People's Liberation Army (PLA) which began in the late 1970s had three major focuses. First, under the political leadership of 3rd paramount leader Deng Xiaoping, the military became disengaged from civilian politics and, for the most part, resumed the political quiescence that characterized its pre-Cultural Revolution role. Deng reestablished civilian control over the military by appointing his supporters to key military leadership positions, by reducing the scope of the PLA's domestic non-military role, and by revitalizing the party political structure and ideological control system within the PLA.
