Expropriative anarchism (Spanish: anarquismo expropiador) is the name given to a practice carried out by certain anarchist affinity groups in Argentina and Spain which involved theft, robbery, scams and counterfeiting currency. The robberies done were called "expropriations on the bourgeoisie". It had its major peak between 1920 and 1935 and some of its most famous practitioners were Buenaventura Durruti, Francisco Ascaso, Severino Di Giovanni, Miguel Arcángel Roscigna, and Lucio Urtubia.
