Democratic polities continue to be faced with politics of resentment. Along with resurgent counter-cosmopolitanism and anti-immigrant prejudice, various political agents have mobilized old and modernized antisemitism in European democracies. The first comparative study of its kind, this book rigorously examines the contemporary relevance of antisemitism and other politicized resentments in the context of the European Union and beyond. Presenting new approaches and state-of-the-art research by leading authorities in the field, the volume combines comparative work and political theorizing with ten single country studies using qualitative and quantitative data from Eastern and Western Europe. The result is a new and sober set of arguments and findings, demonstrating that antisemitism and counter-cosmopolitan resentment are still all too present human rights challenges in today’s cosmopolitan Europe.
