I just want to make sure that some other flaired members see this question, since I focus on the military and ideological aspects of the war and they may have more on the anarchist side of things.

/u/Georgy_K_Zhukov, /u/tobbinator, /u/k1990.

I also have a clarifying question: do you mean to inquire about the influence of the Anarchists on the Spanish Civil War and Revolutionary Catalonia, or how influential the Anarchists that participated in the Spanish Civil War and Revolutionary Catalonia were on other subjects/people/movements?
