The Regional Defence Council of Aragon (Spanish: Consejo Regional de Defensa de Aragón (CRDA), Aragonese: Consello Rechional d'Esfensa d'Aragón), was an administrative entity created by the Confederación Nacional del Trabajo (CNT) in the context of the Spanish Revolution, during the Spanish Civil War. Until its dissolution, the CRDA controlled and administered the eastern half of Aragon. Its economy was based on the communities, the productive engine of the region, as well as the exchange between them and other regions. The price of goods was controlled and inflation was avoided.
