Objective: to investigate the ways in which the detached/demobilized people of the armed conflict get to redefine a sense of life in the transition process to civilian life, taking into account the contribution of the different support networks that accompany them. Method: qualitative research. A narrative analysis based on deep interviews conducted within people who were active in illegal armed groups like the FARC-EP, ELN and AUC. Results: the research findings allowed us to understand that the sense of life –before, during and after their experience within the armed groups–, is transformed from context, particular experiences, personal motivations, the learning acquired and the relationship with support networks. Conclusions: it is considered that the narratives allow a process of reconstruction of the meaning of life through a memory exercise, providing an opportunity for social recognition from life experiences. This involves challenges for psychosocial support, aimed at promoting the active participation of the civil society and the detached and demobilized population in peace building processes.
