In an increasingly global and systematically fragmented world, war continues to generate victims. Thus, men, women, and others of different gender identities have suffered the horrors emanating from violent conflicts among human beings. Their forms of suffering vary, however, because women and people of other gender identities experience and suffer from these conflicts differently. The goal of this work is to disseminate a series of studies and reflections on war from a gender perspective. This book presents a series of research related to the Colombian armed conflict, specifically explores novel topics such as obstetric violence or victimization of women in connection with the crime of forced disappearance of people. It also includes the development of classic themes of legal literature with a gender focus related to the responsibility of the State and the employment of women as instruments of war.
