This paper investigates the linkages between feminist movements and women’s policy agencies in post-dictatorship Argentina, Brazil and Chile. It focusses on how they articulate to pass legislation on women’s political representation, including the descriptive, substantive and extra-parliamentary dimensions. Covered topics are electoral gender quotas, women’s policy national plans/conferences and political reforms. The qualitative research adapts the conventional state feminist model by replicating RNGS first phase of systematic study of women’s policy agencies and feminist movements and adds specific legislation systematizing women’s political representation. We employ documentary analysis, semi-structured interviews and advocacy evaluation. The theoretical referential comprehends the contemporary literature on women’s political representation (e.g. Childs and Lovenduski, 2013; Archenti & Tula, 2008; Avelar, 2001; Tremblay, 2007; Phillips, 2001) and state feminism (Lovenduski, 2008; McBride and Mazur 2013; Costa, 2008; Largo, 1998). The conditions in the selected countries challenge state feminist concepts and advance our understanding of their comparability.
