Although the Nordic countries have a reputation for tolerance and social demacy, they were not immune to fascism which spread across Europe in the 1920s and 1930s. This book offers the first comprehensive history of anti-fascism in the Nordic Countries. Through a number of case studies on anti-fascism in Sweden, Finland, Norway, Denmark and Iceland, the book makes a significant contribution to the history of contentious politics in the Nordic Countries and to our broader knowledge of European fascism and anti-fascism. The case studies concentrate on the different manifestations of resistance to fascism and Nazism in the interwar era as well as some of the postwar variants. The book will be of considerable interest to scholars of anti-fascism as well as researchers of Nordic and Scandinavian history and politics.
