Europe has experienced the most radical reallocation of authority that has ever taken place in peacetime over the past half-century. However, the ideological conflicts emerging from this development are only now becoming apparent. This collection brings together an authoritative group of scholars of European and comparative politics to investigate patterns of conflict arising in the European Union. The contributors to the volume conclude that political contestation concerning European integration is rooted in the basic conflicts that have shaped political life in Western Europe for many years.
