Following conflict, peace agreements bring an opportunity to profoundly change societal structures and add to women’s empowerment. Using affirmative action tools like electoral gender quotas, women’s numerical presence, or descriptive representation, has more than doubled since the 1995 Beijing Declaration. However, women’s descriptive representation does not always result in women’s representation beyond numbers, or substantive representation. This thesis aims to solve why quotas do not always lead to a rise in women’s substantive representation by exploring one possible explanation: the effect of women’s rights provisions in peace agreements on the outcomes of electoral gender quota-implementation. It argues that women’s rights provisions in peace agreements can affect policymaking outcomes in the postwar context in terms of increased substantive representation of women. The thesis employs the method of structured, focused comparison to compare the two post-war countries, Nepal and Angola. It finds support for the hypothesis that electoral gender quotas implemented following a peace agreement with women’s rights provisions leads to a larger increase in women’s substantive representation than those implemented following a peace agreement without such provisions. However, further qualitative cross-case analysis and large-n quantitative research are needed to draw more certain conclusions.
