Against the backdrop of combating the financial and economic crisis in the European Union for the past decade, this volume strives to explore the manifold impacts the prevailing crisis management has on the further alignment of European Integration. The efforts targeted at overcoming the financial and economic crisis evoked far-reaching consequences on the societal, economic, and political level within European member states, which in turn challenge the institutional alignment, democratic legitimacy and economic coherence of the European Union. Taking into account current developments in the EU, the contributions presented in this volume focus on the ‘fault lines’ in the integration process, i.e. questions of policy coherence, democratic accountability, financialization, militarization, migration, gendered social and economic asymmetries as well as the rise of populist and extreme right-wing parties. The volume focuses on how these different developments come together by relating aspects of transdisciplinary research to uncover the fault lines in the European integration project in the subsequent chapters.
