The Popular Front (Spanish: Frente Popular) was an electoral alliance and pact formed in January 1936 to contest that year's general election by various left-wing political organizations during the Second Spanish Republic. The alliance was led by Manuel Azaña. In Catalonia and the modern-day Valencian Community, the coalition was known as the Front of the Lefts (Catalan: Front d'Esquerres).
The Popular Front included the Spanish Socialist Workers' Party (PSOE), Communist Party of Spain (PCE), and the republicans: Republican Left (IR), (led by Azaña) and Republican Union (UR), led by Diego Martínez Barrio. This pact was supported by Galician (PG) and Catalan nationalists (ERC), the POUM, socialist union Workers' General Union (UGT), and the anarchist trade union, the Confederación Nacional del Trabajo (CNT). Many anarchists who would later fight alongside Popular Front forces during the Spanish Civil War did not support them in the election, urging abstention instead.
