Member States of the European Union combines geographic and thematic coverage to provide a comprehensive and nuanced overview of the building blocks of the European Union - its member states. The third edition explores the key concepts of statehood and Europeanization, analysing the wide-ranging impact of Europeanization on member state institutions, political parties, social movements, public policy and the European political economy. New coverage includes state responses to the refugee and climate crises and two new chapters dedicated to Bulgaria and Greece. A fully-updated chapter on the United Kingdom illustrates the tensions between Europeanization and member statehood, exploring the implications of the UK's vote to leave the EU. It is the ideal text for all those studying EU Politics with an interest in the member states of the European Union and how they work together.
