Dual nationality is a contentious issue in both the US and Europe. Contending that theirs is the first volume since Bar-Yaacov's 1961 book to focus primarily on this topic rather than simply on citizenship, Hansen (politics, Oxford U.) and Weil (Centre for Research on the History of Social Movements and Trade Unionism, Paris I-Sorbonne) introduce the pro and con arguments in historical and normative contexts. In 13 chapters, scholars examine the problems and possibilities of dual citizenship in Germany, the UK, France, and North America, and the related issues of gender and social rights, European Union citizenship, and the overlooked question in nationality law of nationality within a federation.
