Migration is considered one of the most pressing challenges in Europe in the 21st century. In the wake of mass migration to Europe in recent years, practices, and policies of “integrating” newcomers have been high on European political agendas. Confronted with the seemingly “unprecedented” events of the 2015/2016 “refugee crisis”, and most recently, millions fleeing the war in Ukraine, the continent’s long history of forced-migration and displacement is apparently often ignored. The end of the Second World War has produced the largest wave of displacement in Europe’s history so far. Despite the wealth of historic experiences, we still seem to know little about the long-time cultural and social impacts of past migrations. Many pressing questions remain unanswered. Especially when it comes to understanding past dealings with vulnerable groups of forced-migrants. In this panel, we analyse the history of specific groups of forced migrants from Europe between the 1930s and the 1950s. This period that has frequently been described as “age of displacement” witnessed the establishment and negotiation of new and - in fact - global migration regimes, as we argue. The panel papers analyse different aspects of vulnerability and different groups of vulnerable people over a period of two decades and in a wide geographical context. They range from unaccompanied minors in wartime Australia, American support schemes for Austrian former enemy aliens, the contributions of women's organizations to the rehabilitation of displaced female academics and displaced single mothers, to welfare work with unaccompanied children in Postwar Austria.
