The underlying theme of this edited collection is gendered citizenship, as well as the challenges and limits that confront the gendering of citizenship. It critiques the notion of the genderless nation-state citizen — in both analytical and policy terms and contexts — and necessarily engages with at least three major sets of contradictions or tensions: limitations on achieving gender equal or gender equitable citizenship; relations and differences between gender equality policy, diversity policy, and gender mainstreaming; and interplays of academic analyses of and practical interventions on gendered citizenship. Contributors from diverse scientific disciplines and academic backgrounds aim to provide a better understanding of the challenges that societies within Europe and elsewhere face vis-à-vis diversity, regionalism, transnationalism, and migration.
