This book analyses how domestic and European structures impact on national actors' identities, interests and foreign policy practices. Employing Norway as the case study area, the author uses this nation as an example to assess Europeanization and identity politics across the European Union (EU). Utilising an original and innovative approach called 'social constructivist fusion perspective', the author addresses Europeanization across several key factors. The author assesses the influence of the EU on 'half-way member countries', and the impact of identity politics and domestic structures, which factors contribute to or hinder Europeanization, and attempts to empirically measure Europeanization at the actor level. It analyses the impact of domestic and European structures on the identities, interests, attitudes and foreign policy practices of the Norwegian policy-makers. Whilst contributing to knowledge and literature on how constructivist approaches can be utilized in empirical studies of political elites, this book goes beyond theory to demonstrate that Europeanization is not only institutional, and provides evidence of the influence of identity politics. Europeanization, Integration and Identity will be or interest to students, scholars and policy-makers in the field of European Union politics, international relations, social constructivism and Scandinavian politics.
