A las Barricadas (To The Barricades) was one of the most popular songs of the Spanish anarchists during the Spanish Civil War. A las Barricadas is sung to the tune of Warszawianka 1905. The lyrics were written by Valeriano Orobón Fernández in 1936. "The Confederation" referred to in the final stanza is the anarcho-syndicalist CNT (Confederación Nacional del Trabajo — "National Confederation of Labour"), which at the time was the largest labour union and main anarchist organisation in Spain, and a major force opposing Francisco Franco's military coup against the Spanish Republic from 1936–1939. Black storms shake the sky Dark clouds blind us Although death and pain await us Duty calls us against the enemy The most precious good is freedom And we have to defend it With courage and faith Raise the revolutionary flag Which carries the people to emancipation Raise the revolutionary flag Which carries the people to emancipation Working people march onwards to the battle We have to smash the reaction To the Barricades! To the Barricades! For the triumph of the Confederation To the Barricades! To the Barricades! For the triumph of the Confederation
