As peacebuilding discourses increasingly stress the importance of including women, to what degree have security-related practices taken heed? It has been over 10 years since the United Nations Security Council passed Resolution 1325 on Women, Peace, and Security, yet it remains a “confused and confusing” tool for scholars and practitioners in assessing women’s inclusion in peacebuilding. This article adds to our understanding on women and peacebuilding by engaging 1325 as an operationalizable concept and then applying it to peace agreements to understand how women’s security is addressed as part of formal peace processes. Given previous difficulties in operationalizing 1325’s mandate, this article engages it as a three-level concept useful for studying the ways in which women are “brought into” security, called (en)gendered security. Using this concept of (en)gendered security, I assess intrastate peace agreements between 1991 and 2010 to elucidate where and how women are included in peace processes. This article illustrates the potential of a systematized and practical approach to security embodied in 1325 and a preliminary discussion of what accounts for better approaches to (en)gendered security during peacebuilding.
