In 1926, the Fascist government of Benito Mussolini outlawed the Communist Party. Although forced underground, the PCd'I maintained a clandestine presence within Italy during the years of the Fascist regime. Many of its leaders were also active in exile. During its first year as a banned party, Antonio Gramsci defeated the party's left-wing which was led by Amadeo Bordiga, becoming the new Secretary during the party's congress in Lyon and issued a manifesto expressing the programmatic basis of the party. However, Gramsci soon found himself jailed by Mussolini's regime and the leadership of the party passed to Palmiro Togliatti. In 1930, Bordiga was expelled from the party on the charge of Trotskyism. The same fate had already occurred to members of the party's right-wing.
