Focusing on how domestic actors have framed Europe/EU norms in the debates on territorial reforms and the implications of this framing on policy reforms, it asks how competing articulations of the EU and its norms construct state territoriality in the given political and policy debates. The book argues that the European Union acted as a discursive force and a challenge to the established structures of understanding of territoriality, statehood, and power. With this, the author proposes a new research model for the study of Europeanization that goes beyond the neo-institutionalist account of the EU's policy/norm transfer to member/non-member states. This text will be of key interest to students, scholars and practitioners of European integration, EU foreign policy, enlargement policy, and regional policy and territoriality in post-socialist spaces.
