This is an analysis of the international legal order from the feminist perspective. It argues that the institutions, methodologies and substantive principles of international law are gendered in that they are based on the realities of male lives. The book draws on a range of feminist theories to discuss the theories, sources and institutions of international law, the role of the state in international law, human rights law and the law relating to the use of force and the peaceful settlement of disputes. It concludes by assessing the potential for international law to further the advancement of women.
