The PSUC (Partit Socialista Unificat de Catalunya, Unified Socialist Party of Catalonia), was formed through the unification four left groups, namely the Catalan Federation of PSOE, Partit Comunista Català (Catalan Communist Party, the Catalan branch of PCE), Unió Socialista de Catalunya (Socialist Union of Catalonia) an Partit Català Proletari (Proletarian Catalan Party), in Catalonia on July 23 1936. The PSUC played a major role during the days of the Second Spanish Republic and the Spanish Civil War.

PSUC was the only "regional" party affiliated to ComIntern. The Communist Party of Spain (PCE) did not organize in Catalonia, but saw PSUC as its Catalan referent.

During the Franco regime PSUC was outlawed and worked clandestinely and in exile. PSUC was the largest opposition party in Catalonia, and at the fall of the regime it became a mass party.

In 1977 PSUC was legalized.

Gradually PCE and PSUC started going in separate ways. PSUC became involved in Iniciativa per Catalunya, and gradually ceased functioning as a separate party. When PSUC was completely submerged into IC in 1997, a group of hardliners refounded the party as PSUC viu (Living PSUC). PSUC viu became the new referent of PCE in Catalonia.
