This chapter studies the accession-driven Europeanisation of citizenship in the Czech Republic, Slovakia and Croatia. Drawing from Bourdieu’s field theory and Isin’s critical intervention into citizenship scholarship, the chapter explains how European citizenship has shifted domestic citizenship practices away from the central state and towards the subnational and the European political spheres. It argues that the analysis of the citizenship practices of actors outside of the EU helps us to redefine European citizenship as a regime that transcends the boundaries of the EU. Two principal claims are made. First, European citizenship functions as an organising principle of political spaces that are not directly part of the European Union, including transnational networks, cross-border regions, but also non-EU localities. Second, by claiming rights vis-à-vis European institutions, citizens of EU applicant/candidate countries have not only positioned themselves as political subjects within the EU, but they have also pushed for a more democratic and inclusive European order.
