The Zapatista Army of National Liberation (Ejército Zapatista de Liberación Nacional, EZLN) is an armed revolutionary group based in Chiapas, one of the poorest states of Mexico. Their social base is mostly indigenous but they have supporters in urban areas as well as an international web of support. Their most visible voice, although not their leader, is Subcomandante Marcos (currently a.k.a. Delegate Zero in relation to the "Other Campaign"). Their leader is Comandanta Esther. Unlike the Zapatista comandantes, Subcomandante Marcos is not an indigenous Mayan.

The group takes its name from the Mexican revolutionary Emiliano Zapata; they see themselves as his ideological heirs, and heirs to five hundred years of indigenous resistance against imperialism.

Some consider the Zapatista movement the first "post-modern" revolution: an armed, yet non-violent (despite an uprising in the early 1990s) revolutionary group that incorporates modern technologies like satellite telephones and the internet as a way to obtain domestic and foreign support. They consider themselves part of the wider alter-globalization, anti-neoliberalism movement. -Wikipedia
