 Known as the Years of Lead, this period was characterized by widespread social conflicts and terrorist acts carried out by extra-parliamentary movements.The assassination of the leader of the Christian Democracy (DC), Aldo Moro, led to the end of a "historic compromise" between the DC and the Communist Party (PCI).In the 1980s, for the first time, two governments were managed by a republican (Giovanni Spadolini 1981–82) and a socialist (Bettino Craxi 1983–87) rather than by a Christian-democrat.
