This chapter introduces the developments of and research on political actors called populist in the Nordic countries. The focus is on contemporary populist right-wing parties – the Sweden Democrats, the Danish People’s Party, the Finns Party, and the Norwegian Progress Party – though we discuss the history of Nordic populist parties on a more general level as well. Nordic research on populism has for the most part adopted political scientific, ideational, and empirical perspectives lacking genuine theoretical considerations. However, contextual differences can be found, and sociological and cultural approaches to studying populism have been promoted of late. The perspective on populism in media and communication studies has concentrated especially on the political communication of populist actors and the relationship between the media and populism. The future challenges for Nordic populism studies are linked to changing media and political environments, requiring a new look at their relationship.
