After democracy was restored in Argentina in 1983, the government set up the National Commission for Forced Disappearances (CONADEP), led by writer Ernesto Sabato. It collected testimony from hundreds of witnesses about victims of the regime and known abuses, documenting hundreds of secret prisons and detention centers, and identifying leaders of the torture and death squads. Two years later, the "Juicio a las Juntas" (Trial of the Juntas) largely succeeded in proving the crimes of the top officers of the various "juntas" that had formed the self-styled National Reorganization Process. Most of the top officers put on trial were convicted and sentenced to life imprisonment, including Jorge Rafael Videla, Emilio Eduardo Massera, Roberto Eduardo Viola, Armando Lambruschini, Raúl Agosti, Rubén Graffigna, Leopoldo Galtieri, Jorge Anaya and Basilio Lami Dozo.
