This chapter examines feminist perspectives on international relations. It first provides a historical background on the development of feminist IR, paying attention to feminist analyses of gender, before outlining a typology of feminist international relations, namely: liberal feminism, critical feminism, feminist constructivism, feminist poststructuralism, and postcolonial feminism. It then considers feminist perspectives on international security and global politics, along with developments in feminist reanalyses and reformulations of security theory. It illustrates feminist security theory by analysing the case of the United Nations Security Council sanctions on Iraq following the First Gulf War. The chapter concludes by assessing the contributions that feminist IR can make to the practice of world politics in general and to the discipline of IR in particular.
