What is the black and red flag all about?
The flag originated in the 1930s in Spain where members of the anarcho-syndicalist CNT (our Spanish sister-section in the International Workers’ Association – IWA) combined the red flag of the workers’ movement with the black flag of anarchism, mirroring the application of anarchist politics to the workers’ movement represented by anarcho-syndicalism. After it was made famous by the CNT in the Spanish Revolution of 1936, all sorts of other anarchists also adopted the flag but those are its origins.
