Diversity in the European Union encompasses the national cultures and languages of the member states, but increasingly also assertions of difference within European societies. Immigrants have brought to the fore religious, ethnic, and racial diversity, sexual minorities have demanded equal rights, and regional and cultural minorities have clamored for recognition and participation. This volume provides an overview of EU actions seeking to manage diversity, introduces a conceptual framework to think about diversity in the European Union, and provides a tapestry of cases that illustrate minority politics and activism, contestations over identity and difference, and the construction of new meanings of European citizenship.
