Gender has always been central to the practice and representation of war as well as to efforts to oppose war and rebuild societies in its aftermath. Feminist theorizing about gender and war, however, has only gained visibility and legitimacy in both the academy and among policymakers in the past three decades. The result is an impressive body of interdisciplinary literature that has gone far beyond its original home in disciplines such as International Relations. As the contributions to this Handbook underscore, feminist-informed scholarly debates on gender and war have expanded to include sociologists, anthropologists, historians, economists, geographers, and communication and media scholars, as well as scholars based in interdisciplinary fields like gender and sexuality studies and ethnic studies. Furthermore, this growing field of study is informed not only by academic research but also by discussions among policymakers and activists. As such, the literature on gender and war, and this Handbook in particular, are designed both for students and faculty committed to understanding the gendered dimensions of war. All the chapters in the Handbook include information relevant to activists, advocates and policymakers who want to reflect on their experiences and explore best practices to address the gendered aspects of war and political violence.

The first phase of feminist theorizing on gender and war dates back to the 1980s and reflects efforts to make women visible in studies of war and its multiple effects. The literature that emerged during this period was primarily
