Anarchist Aragon (July 21, 1936 – 1939) was a period in Aragon's history, within the larger context of the Spanish Revolution, characterised by collective land ownership reform, social redistribution, communalisation of agrarian areas, attempt to eliminate the social influence of the Catholic Church, and worker economic and political management largely without the direction of a state. The period is generally agreed to have started at the Siege of the Alcázar, a highly symbolic Nationalist victory in Toledo in the opening stages of the Spanish Civil War, although anarchist communist thought was widely prevalent in such areas as Andalusia, the Levante, most of Aragon, as well as in Anarchist Catalonia. Mass collectivisation and the broad implementation of libertarian communist ideas occurred very quickly, largely voluntarily.
