This paper presents some of the effects of Colombia´s armed conflict in people who were displaced from their territories, and the institutional mechanisms proposed to address this problem. The author studies the cases of El Salado (Bolívar Department) and Nueva Venecia (Department of Magdalena) in a research conducted in these populations after the massacres of the years 2000 by paramilitary groups, and articulates the notions of violence and memories in order to question the current interventions on them in terms of transitional justice.
