| Politics is essentially about conflict over issues. Yet, limited knowledge exits of factors explaining why certain issues become object of heightened conflict at a particular time or in a particular country. This study enhances our understanding of issue evolution by comparing political conflict over immigration and European integration in five institutionally highly similar political systems, which vary in the extent to which both issues have been politicised: the Netherlands, Flanders, Denmark, Sweden and Wallonia. Three interrelated PhD projects study the roles and reciprocal influences of the media, citizens, and parties in the politicisation of immigration and European integration. |
