The Rebel Zapatista Autonomous Municipalities (Municipios Autónomos Rebeldes Zapatistas) (MARZ) are an apparently anarchist structure of government in rural Chiapas, Mexico. I can find very little information about them; the Wikipedia paged (linked above) cites no sources and the Chiapas Support Committee website is not very well updated.
I'm also confused because Wikipedia mentions that in the Rebel Zapatista Autonomous Municipalities (Municipios Autónomos Rebeldes Zapatistas), the Zapatista Army of National Liberation (Ejército Zapatista de Liberación Nacional) “does not hold any power”, yet it also describes that “the councils of good government providing low-interest loans, free education, radio stations and health-care to communities”, where the “councils of good govenment” page redirects to the Zapatista Army page.
There have historically been very few anarcho-socialist government areas. The POUM during the Spanish Civil War was apparently libertarian Marxist, the POUM was suppressed first by Stalinists and then by Fascists. Rojava is more recent and ongoing, but operates within the context of the Syrian Civil War, which is a severe confounding factor for any form of development. Therefore, social, environmental, and economic development within the MARZ would seem to provide a unique opportunity to study anarcho-socialism in action.
Are there any independent studies?
