• Sommario/riassunto: Shedding new light on the issues concerning refugees and immigration in 20th-century Sweden, this analysis examines the implications of its immigration policies. On what grounds were refugees admitted? Where did they come from? How did the Swedish state aid its new citizens? What differences were there between refugees and the "imported labor" that was essential to Swedish industry? A group of established Swedish and international historians answer these questions against the background of the eras passed: the Second World War, the Cold War, and the labor movement that shaped the national char
