This paper seeks to uncover the roles played by truth commissions in Latin America in establishing transitional justice, in a comparative study that draws upon three main experiences: Argentina, Chile, and Peru. It highlights the contexts that allowed these experiences to adhere to the democratic transformation and absorb its complexities, by questioning the dynamics that accompanied the establishment of truth commissions, and identifying the roles of actors in managing tension between the demands of victims and the requirements of reconciliation and civil peace. The paper demonstrates that the establishment of truth commissions was linked to the nature of the challenges faced by Latin countries undergoing democratization and transcending the legacy of previous violations. Inasmuch as these challenges reduced the crisis of legitimacy that ravaged these systems and led them to engage in this transformation, they also highlighted the potential that these committees have provided for actors to manage the sequence of this shift.
