"This thesis analyzes reintegration as part of peace construction and state building in Colombia. It enquires how ex-combatants' political identities are transformed within the Colombian reintegration program through micro-level reintegration practices and interpersonal negotiations thereof. Thereby, it seeks to unpack what kind of citizens ex-combatants are to become for the envisioned 'post-conflict' state and what possibilities of agency to shape such normative expectations and practices they have through their participation in the reintegration program.
