This article presents the implementation of the right to the truth of the victims, through the creation of eleven Commissions of Truth, established in Argentina, Chile, El Salvador, Guatemala, Uruguay, Peru, Paraguay, Colombia, Ecuador, Honduras and Brasil, which emerged as the product of peace agreements or transitional processes. The Commissions of Truth received the assignment to investigate violations of Human Rights and breaches of International Humanitarian Law by military dictatorships, authoritarian regimes or internal armed conflicts. This review shows, that in addition to the subjects that constitute the Commissions, they work due to eight conditions: determined duration; legitimacy; themes; working methodologies; media of dissemination of results; attention to Disarmament, Demobilization and Reintegration processes; repair strategies, request for forgiveness and reconciliation. The existence of the Commissions of Truth, while transforming the conflicts they serve, have not reached, as a strategy, the integral promotion of connivance and reconciliation.
