Partit dels Socialistes de Catalunya

The Partit dels Socialistes de Catalunya is a Socialist party with its own organisation in Catalonia. Its foundation united the Partit Socialista de Catalunya (Congrés), the Catalan federation of PSOE and the Partit Socialista de Catalunya (Reagrupament). The merger brought together political currents that had previously competed within Catalan socialism.

The resulting party retained its own legal personality and finances while establishing a unity protocol with PSOE. That agreement provides participation in PSOE's federal bodies alongside autonomy in Catalan politics. The relationship therefore joins two distinct organisations. A PSC councillor's municipal vote, a decision by the Catalan party and an action by Spain's national government belong to different institutions. The party's history and organisational agreement explain its place in Spanish socialism more fully than any single local housing vote.
