The Spanish Revolution was a workers' social revolution that began during the outbreak of the Spanish Civil War in 1936 and resulted in the widespread implementation of anarchist and more broadly libertarian socialist organizational principles throughout various portions of the country for two to three years, 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 like hotels, barber shops, and restaurants were also collectivized and managed by their workers.
