Catalan State Proletarian Party

Catalan State-Proletarian Party (Catalan: Estat Català-Partit Proletari, EC-PP) was a communist political party in Catalonia, Spain. It was formed in 1932 by the left-wing sector of Estat Català (EC), those who did not approve of group merging into the Republican Left of Catalonia.

Leaders of EC-PP were Jaume Compte, Ramon Fabregat, Pere Aznar and Artur Cussó. EC-PP published L'Insurgent.

EC-PP made fruitless attempts to rally other forces to join a united party, and, in the end, it launched the Proletarian Catalan Party (January 1934).
