This book investigates the question of why, despite European integration and its challenges to state sovereignty, separatist nationalism continues to thrive in European Union member states. Janet Laible argues that the EU, as a context, a set of resources, and a participatory arena, is deeply implicated in the arguments and tactics of separatists. Contrary to those who believe that European integration has reduced the incentives for separatist politics, Laible draws on evidence from contemporary Scottish and Flemish nationalism to demonstrate that the EU sustains the importance of statehood and therefore separatism, and creates new forms of political capital that nationalists employ in their struggles for self-government.
