The origins of this organization go back to the 1950s, when some former partisans of GAAP (Anarchist Groups of Proletarian Action) who supported the FCL (Libertarian Communist Federation), and who were subsequently expelled from FAI (Italian Anarchist Federation) because they became Leninists, subsequently joined the group called "Azione Comunista." It had been expelled from the Italian Communist Party (PCI) as a result of the position it had taken in favor of the 1956 Hungarian insurgents, who were harshly repressed by the Soviets. Stalinism was defined as the reactionary policy of the counterrevolution after the death of Lenin. The group also protested against the positions of the Italian Communist Party, considered dependent on the Communist Party of the Soviet Union (CPSU) and dominated by the foreign policy of the USSR. It was also considered in collusion with Italian capitalism. This situation would have strengthened the geopolitical structure that was emerging and so that would have prevented emergence and development of Marxist and internationalist forces.
