This thesis discusses how conflicts and violence turn mothers into activists. Through a theoretical-literary framework that constructs what constitutes political motherhood, it seeks to understand the departure of mothers from the private to the public sphere and how the collectivization of mourning presents gendered dimensions. To discuss the relationality present in the collective, an approach to the ethics of care revised to encompass current moments and relationships is used. To this end, a case study is carried out on the collective Mothers of False Positives (MAFAPO) in Colombia, discussing the 16 years of impunity in the face of the Soacha scandal in 2008 that coined the dead men as false positives. In light of the state violence committed by the Colombian Army and former President Álvaro Uribe (2002-2010), the thesis discusses mourning, memory and justice from the perspective of mothers who became activists and what possibilities they found during all these years to live with the fact that their sons/husbands/brothers were murdered and called guerrillas.
