The Control Patrols of the Central Committee of Anti-fascist Militias of Catalonia was an anarchist militia controlled by the CNT-FAI and operating in Catalonia during the first year of the Spanish Civil War.
The organization was created in the August 1936 with the mission of prosecuting collaborators of the military revolt. After a very violent phase followed by a progressive control of the Generalitat of Catalonia, the patrols were dissolved in June 1937 due to the military and political control taken by the Communist Party of Spain and other pro-Soviet forces. During their short period of existence, these groups detained and executed thousands of members of The Church, Carlists, and other people against the revolution in Barcelona and the surrounding areas.
