This research analyzes how truth-finding and truth-telling practices develop in the public sphere during a transition from armed conflict to “peace.” Truth Commissions and their final reports in Latin America (El Salvador (1992), Guatemala (1999), and Colombia (2022)) will be read, contrasted and interpreted, along with their corresponding post-accord contexts, via a hermeneutical-phenomenological approach and in dialogue with Hannah Arendt’s political thought, particularly her interpretations on truth and politics in the public political sphere after mass atrocities. Consequently, Arendt’s theory will be tested over against the experienced truth finding efforts in the cases studied. This research aims to contribute to the ongoing academic and social-political debate around the proposed condition of truth-telling for a sustainable “just peace” and the non repetition of violence, and draw lessons for post peace-accord processes in divided societies by armed conflict and systematic human rights violations.
