This article seeks to explain the rise of pro-gender norms and feminist strategies in foreign policy, which are increasingly salient in global politics. How can this trend be theorized? In what ways is this development resisted and contested by other states and international actors? To what extent can we trace continuity and change in regard to gender and foreign policy? To address these major research questions and to spur cross-national comparative studies, this article advances a theoretical framework on gendering foreign policy. It draws on two strands of research, which rarely engage with one another: international feminist theory (IFT) and foreign policy analysis (FPA). We identify three ways in which comparative analysis of gender in foreign policy can be advanced: first, by highlighting the variations of pro-gender norms and enhancing the analytical assessment of cross-national trends; second, by generating a more robust explanation of the rise, embeddedness, and continuity of, as well as resistance to, pro-gender norms in foreign policy in similar and diverse contexts; and third, by examining both continuity and change in pro-gender norms in order to reveal the contestation around gender, which is at the heart of foreign policy.
