The Spanish Revolution was a workers' social revolution that began at the outbreak of the Spanish Civil War in 1936 and for two to three years resulted in the widespread implementation of anarchist and, more broadly, libertarian socialist organizational principles throughout various portions of the country, primarily Catalonia, Aragon, Andalusia, and parts of the Valencian Community. Much of the economy of Spain was put under worker control; in anarchist strongholds like Catalonia, the figure was as high as 75%. Factories were run through worker committees, and agrarian areas became collectivized and run as libertarian socialist communes. Many small businesses, such as hotels, barber shops, and restaurants, were also collectivized and managed by their workers.

Named after Buenaventura Durruti, it was founded on 15 March 1937 by Jaume Balius i Mir and Félix Martínez, who had become disillusioned with the policies of the CNT-FAI's leadership. During the May Days in Barcelona, they actively agitated among the anti-government forces, advocating for the formation of a "revolutionary junta", in close collaboration with Spanish Trotskyists. Following the suppression of the uprising, the group began published the newspaper El Amigo del Pueblo, in which they denounced the CNT-FAI for "collaborationism", resulting in their expulsion from the organisation. Their 1938 pamphlet Towards a Fresh revolution, which reaffirmed their proposals for a revolutionary junta, became an influential text within the anarchist current of platformism. But the group ultimately failed to make a broader impact within the Spanish movement and collapsed by the end of the war.
