Like other Nordic countries, Sweden has its dark chapter of ignominious history involving discrimination targeting the Roma. However, less is known about the fate of Romani people in the Nordic countries during World War II especially genocidal plans regarding Roma people in the Nazi-occupied Norway as well as the cooperation between the Nazis and the Nordic authorities regarding the so called “solving of the Gypsy Plague”. The paper examines the results of recent research on the history of the Roma in the Nordic countries during World War II, focusing on terminology, preliminary results and dimensions for further research.
