This chapter provides an overview of the intersection between international law and feminism. It predominantly discusses scholarly writing, but also some major documents and institutions. The material first emphasizes how feminism has developed within various international law subfields. Then it focuses on a major offshoot from traditional international legal jurisprudence known as Third World Approaches to International Law (TWAIL). Next, the chapter shows how an international law focus strengthens and broadens traditionally US-oriented feminist legal theory. The related field of comparative law, involving the law of one country or several countries, is briefly covered. The next and major section then highlights Critical Race Feminism, an emphasis on women of color, an area that intersects with every area previously reviewed. The conclusion notes the work that remains to be done.
