During the Spanish Civil War, in the Republican side, a social revolution broke out, led by the workers and their unions ending in many places in a business collectivization process. In the city of Alcoi, the anarchist union took control over more than 100 textile family firms, going through a rationalization process which unified the production of all textile firms overcoming a previous production crisis and attending the war demand. Does the Alcoi case during the Civil War prove the possibility of a successful anarchist business organization? This article tries to understand the development of business without a capitalist organization and the role of business networks in such a development. The organizational design and the administration of the collectivization process is an example of how socialization of the property and democratization of the decision-making process in the company were not opposed with rationality and efficiency, at least during a war context.
