Dual Citizenship as a Path-Dependent Process

Abstract
Over the last few decades, dual nationalities worldwide have increased rapidly. This is astonishing when one considers that a few decades ago citizenship and political loyalty to a national political community were considered inseparable. Overall, there has been a bumpy-line trend towards increasing tolerance. Yet, the degree to which dual nationality is tolerated by states differs. Based on the findings of postnational and national perspectives, this analysis proposes to view tolerance and resistance towards dual nationality as a path-dependent process. The questions dealt with are: What are the factors encouraging the generally increasing tolerance towards multiple nationalities? How can cross-national differences regarding de jure and de facto tolerance towards dual nationality be explained? The main tendency over the past decades has been the growing emphasis on individual rights vis-à-vis state prerogatives in liberal democracies. The expansion of de jure tolerance towards dual nationality is due partly to inter-, supra- and national-level developments, which are connected to diverse factors such as gender equity, understandings of nationhood, immigrant incorporation and general characteristics of the political systems.
