This chapter examines several feminist approaches to the study and practice of international relations. It highlights the similarities between these approaches, but also the differences. It does this first by tracing the interventions made by feminists into international relations and the creation of a distinctly feminist IR agenda. Second, it uses the ‘gender lens’ to demonstrate and analyse how experiences and understandings in international relations can be ‘gendered’. Finally, it explains and examines the critiques made by the different feminist approaches to international relations.
