In recent years there has been a proliferation of studies on a variety of aspects of the EU and gender. In fact, gender and the EU is arguably emerging as a new discipline within the broader scope of EU studies. However, while gender scholars have increasingly consider the EU, they have seldom engaged directly with the founding theories of integration. In this contribution, I consider the relationship between this new field – gender and the EU – and the foundational approaches to studying European integration. How can we pursue a dialogue between feminist discourses and research and the mainstream theories of integration?
