This volume hosts fifteen papers that bring together theoretical, case-based and thematic perspectives on populism, polarisation and emotions. It features proposals for theoretical and methodological innovations, as well as national and regional insights from Brazil, Finland, Germany, India, Italy, Romania and Turkey. In collecting these papers for publication, while aiming for a diversity of topics and regions, we were excited to find such strong interconnections between papers that were consistent with the themes of interest for us at the HEPPsinki research group. These include the following links between polarisation and negative/positive emotions, the context of populism formation and the role played by media in the process, country-specific contemporary and historical explorations and, importantly, the political effects of the Covid-19 pandemic and its (mis-)management.
