This volume explores connections between migration studies and research in the history of Europeanization and Europeaness, areas which have generated much interest in recent years. Beyond histories of European political integration and the intellectual and elite movements that have supported this process, scholars increasingly pay attention to the constructed nature of Europeaness and European identities, and to the multiplicity of ways in which this construction happens. Migrants can be a particularly useful lens on Europeanization processes as they provide a perspective from the periphery in two ways: by providing a view literally from the outside as in the case of those who left the continent or by providing a view from the margins of the European societies within which they live. The collection asks what ’Europe’ meant to migrants abroad – particularly within the transatlantic context – and within the continent during the twentieth century. Contributions from a variety of disciplinary perspectives reflect both on the broader historical context and theoretical implications and highlight specific cases, such as those of European labor migrants to the United States, of transatlantic exiles and emigres, of Latin-American immigrants in present-day Europe, as well as the experience of highly-skilled migrants within the context of the European Union. Can we trace the emergence of European identities among different groups of migrants and, if so, what forms did they take?This book was originally published as a special issue of National Identities.
