This work aims to reconstruct the historical memory of the armed conflict in the Montes de María coastline, province of Sucre, Colombia, in a moment of military confrontations and responses of defenseless civilians to the repertoire of violence caused by armed groups—specifically against the Unión Camilista–Ejército de Liberación Nacional (ELN), the Fuerzas Armadas Revolucionarias de Colombia-Ejército del Pueblo (FARC-EP), and the paramilitary groups present in the Gulf of Morrosquillo. The objective of this study was to determine the reasons that led the community of Libertad to rise in arms and repel the abuses of armed groups by testing two hypotheses: (1) the frequency of victimizing acts consisting of sexual violence against the women of the Libertad village provoked the community to take up arms; (2) the presence of social agents, here called provocateurs of the community response, motivated the community’s social cohesion and armed uprising. The research is developed using a qualitative methodology with a narrative approach that involved a sample of 49 informants, including two focus groups. We provide empirical findings which are pivotal to understanding the reasons why defenseless civilians made the decision to defend themselves with arms against illegal armed groups that invaded their territory and harassed their communities, especially when dealing with an ethnic minority such as Afro-descendants.
