Socialist Organisation of National Liberation

More moderate members of these organizations wanted to enter the mainstream political scene, while more radical factions pointed to the failure of the new regime to persecute former Francoist and move away from their legacy of centralization.

The first PSAN (Socialist Party of National Liberation), incorporated into the anti-Francoist struggle and was one of such organizations to experience two significant splits in this period.

The IPC had a more stabilised organisation after overcoming the serious problems suffered by both OSAN and PSAN-P, and allowed it to attract new militants from other groups such as the Comunistes Catalans Independents.
