This chapter explores the implications of the radical feminist methodology transplanted and translated to Colombia once the domestic women's rights movement embraced international law to advance women's cause in the context of conflict. Radical feminism gained traction internationally at almost the same time transitional justice was emerging and consolidating itself as the legal and legitimate model to help countries entrenched in dictatorships and/or conflicts to move towards democracy and peace. Radical feminism is rooted in an understanding of patriarchy as a system that creates and continuously reproduces sex/gender as hierarchies in which men dominate women. The momentum radical feminism had gained in international law and transitional justice made this development almost inevitable. In 2012, when the peace talks with Fuerzas Armadas Revolucionarias de Colombia—Ejercito del Pueblo started in Havana, Creole radical feminists had consolidated a well-recognized expertise on gender and conflict centred on sexual violence against women.
