Abstract
The development of European integration has meant that member states have experienced Europeanization and as a consequence the EU has become a more politicized issue in domestic politics. Politicization has come over time and as a consequence of the decline of a permissive consensus and takes some very different forms. The chapter considers the place of the domestic politicization of European integration in theories of European integration and then reviews different periods of the history of European integration, highlighting the growing phenomena of Europeanization and politicization. The chapter then looks at Euroscepticism and its meaning and different forms and identifying which parties can currently be identified as Eurosceptic and what issues Euroscepticism blends with in different member states. The chapter then offers a typology for understanding the different ways in which the politicization of European integration plays out in the party systems of member states.
