Partito Comunista Italiano

The Partito Comunista Italiano (PCI) or Italian Communist Party emerged from a secession by the far left from the Italian Socialist Party[?] (PSI) during that body's congress on 21 January 1921 at Leghorn. Amedeo Bordiga and Antonio Gramsci led the split.

The party gained considerable electoral success during the 40 years following 1945.
