This handbook comprehensively defines and shapes the field of Critical European Union Studies, sets the research agenda and highlights emerging areas of study. Bringing together critical analyses of European Union politics, policies and processes with an expert range of contributors, it overcomes disciplinary borders and paradigms and addresses four main thematic areas pertaining to the study of the European Union and its policies: • Critical Approaches to European Integration; • Critical Approaches to European Political Economy; • Critical Approaches to EU’s Internal Security; • Critical Approaches to EU’s External Relations & Foreign Affairs. In their contributions to this volume, the authors take a sympathetic yet critical approach to the European integration process and the present structures of the European Union. Furthermore, the book provides graduate students and faculty with ideas for future research activity and introduces critical analyses rooted in a broad spectrum of theoretical perspectives. The Routledge Handbook of Critical European Union Studies will be an essential reference for scholars, students, researchers and practitioners interested and working in the fields of EU politics/studies, European integration, European political economy and public policy, EU foreign policy, EU freedom of movement and security practices, and more broadly for international relations, the wider social sciences and humanities.
