A fresh alternative to traditional state-centred analyses of the process of European integration is presented in this book. World-renowned scholars analyze the state in terms of its component parts and clearly show the interaction of subnational, national and supranational actors in the emerging European polity. This `multi-level politics' approach offers a powerful lens through which to view the future course of European integration. The contributors' empirical exploration of areas such as regional governance, social policy and social movements underpins their broad conceptual and theoretical framework providing significant new insight into European politics.
