This lecture asks whether nationalism and European integration are on a collision course. It covers the origin and design of the main institutions of the European Union. Next, I consider the rising opposition to European integration since the early 1990s, evident in survey data and popular votes on new Treaties, up to the British 'in/out' referendum, scheduled for 2016-17. What explains Euroskepticism, and what is the future of the European unification project?
