Citizenship and political loyalty to a state have traditionally been considered inseparable, but in recent years, sovereign states have increasingly tolerated dual and multiple citizenships. More than half of all states now tolerate some form of dual citizenship but in an age of increasing transnational insecurity, questions of loyalty to the nation-state have gained renewed prominence.
In this timely collection, leading scholars explore how the increasing tolerance of dual citizenship reveals the growing liberalization of citizenship law and the increasing securitization of citizenship alongside the erosion of popular sovereignty and the changing role of nationalism and nationhood. If dual citizenship is no longer seen as a self-evident absurdity nor the harbinger of postnational citizenship beyond the state then how should it be understood? Examining the expansion of individual rights on one hand and continued prerogatives of states over full membership in the political community on the other, contributors to this book question whether the liberalization of citizenship fundamentally changes the boundaries of the political and transforms the very core of the political sphere.
