 In 1965, the SIFAR intelligence agency was transformed into the SID following an aborted coup d'état, "Piano Solo", which was to give power to the "Carabinieri", then headed by general De Lorenzo.The difficult equilibrium of Italian society was challenged by a rising left-wing movement, in the wake of 1968 student unrest ("Sessantotto").This movement was characterized by such heterogeneous events as revolts by jobless farm workers (Avola, Battipaglia 1969), occupations of Universities by students, social unrest in the large Northern factories (1969 "autunno caldo", hot autumn).
