On the evening of 24 April 1974, the song E Depois do Adeus (After the Farewell) was broadcast on Portuguese radio as a signal to start the military coup against the dictatorship. It was the end of the fascist regime, which had lasted for 48 years. New legislation put an end to censorship and the press constantly reported on the work carried out by the committees. However, the members of these committees were soon accused of carrying out political persecutions and new laws were enforced to avoid this type of abuse, but these in fact facilitated impunity. The purpose of this article is to analyse the laws and procedures which marked the revolutionary period and the development of Portuguese society in the years immediately after 1974.
