[5] The party was founded on 3 July 2009 by Marco Rizzo as Communists – Popular Left (Comunisti – Sinistra Popolare).

[12] Exactly one month after the Conte II Cabinet took office, the party organized a protest in Rome involving hundreds of people.

[14] In November 2021 senator Emanuele Dessì, elected with the Five Star Movement, joined the party, giving it representation in the Italian Parliament.

It assumes a political line openly revolutionary, supporting the need for the overthrow of the capitalist system and the transformation of Italy into a socialist country,[4] rejecting both reformist and revisionist theories.

[22] With regards to the history of the communist movement in Italy, the PC recognizes as leading figures Antonio Gramsci[23] and Pietro Secchia[24] while it takes a highly critical stand on Palmiro Togliatti[25] and Enrico Berlinguer.

It considers such a definition politically meaningless since during Stalin's leadership there is no trace of elements of discontinuity or attempts of overcoming the Marxist–Leninist theory.

Indeed, the PC reckons the instrumental use of the term Stalinism as a functional anti-communist definition developed following the 20th Congress of the Communist Party of the Soviet Union.

The PC underlines that the role of those communist fighters in the partisan armed struggle has been progressively diminished and concealed in contemporary historiography.
