If you want to understand the #SpanishCivilWar's complexities, I strongly recommend Revolution and the State, by Danny Evans. He describes the large #anarchist #movement centered in #Catalonia, and how a multitude of organizations & strategic tendencies existed during the #CivilWar. While #anarchism struggled due to a lack of assistance from Western countries, and attacks by both fascists & Stalinists, compromises (e.g., joining the gov't) also forestalled the #SocialRevolution.
