Following the increase and generalization of repression throughout the entire extra-parliamentary left during the early 1980s, when thousands of activists were imprisoned in "carceri speciali" (special prisons for terrorist and Mafia prisoners), most of the movement disbanded. At the beginning of the 1980s, a few of them entered "Democrazia Proletaria", a far-left party which in the 1970s and 1980s ran for local, national and European elections, achieving however little success. Nevertheless, the movement began to revive in the second half of the 1980s, when occupied social centres (Italian: centri sociali occupati) started to become widespread in the main Italian cities. However, the new Autonomia is profoundly different from the Autonomia Operaia of the 1970s, although there is some continuity in both movement structures, especially the free radio stations and some long-term squatted social centres, such as the CSO Leoncavallo in Milan, and intellectuals, such as Toni Negri and Oreste Scalzone. They have recently returned from their flight in Paris and elsewhere during the 1980s and 1990s, along with some 200 other autonomists.
