Revolutionary Catalonia (21 July 1936 – 1939) was the part of Catalonia (autonomous region in northeast Spain) controlled by various anarchist, communist, and socialist trade unions, parties, and militias of the Spanish Civil War period. Although the Generalitat of Catalonia was nominally in power, the trade unions were "de facto" in command of most of the economy and military forces, which includes the Confederación Nacional del Trabajo (CNT, National Confederation of Labor) which was the dominant labor union at the time and the closely associated Federación Anarquista Ibérica (FAI, Iberian Anarchist Federation). The Unión General de Trabajadores (UGT, General Worker's Union), the POUM (Workers' Party of Marxist Unification) and the Unified Socialist Party of Catalonia (PSUC, which included the Communist Party of Catalonia) were also prominent.
