In this doctoral dissertation I seek to reflect about the problem of war from the standpoint of the Zapatistas communities in first place, and also from the perspective of those who have followed and thought the multiple meanings and manifestation of that war through their labour in defence of Human Rights, in academic and activist engagements. Furthermore, I show how, in the articulation of every-day resistance, in seeking indigenous autonomy, other possible worlds are created. Methodologically, this dissertation approaches a multi-sited ethnography, in which thoughts enrooted in diverse positions and localisations are articulated around the Zapatistas communities presence. Hence, I intend to instigate those meanings about the phenomenon of war, but also about freedom, resistance, the possible ways out from war, solidarity and social networks, among others. In mobilising those articulations between thought and practice, a heuristic tool is generated, as a possibility of comprehension about both war and autonomy, in terms of liberation in the Zapatista territories. That way, to finish, I trace a possible interpretation of International Relations as a scholarly field, and of security as a study object, in decolonial terms.
