Migration is an increasingly important reality for sub-national autonomous territories characterized by large historical communities or minorities. The diverse claims of these groups, on the one hand, and of new communities arising from migration, on the other, bring complexity to the management of migration issue in the territories. Migration and Autonomous Territories , edited by Roberta Medda-Windischer and Andrea Carlà, draws on the fields of migration and minority studies, to analyze the challenges associated with the need to reconcile diversity and unity in autonomous territories. The volume compares the cases of South Tyrol and Catalonia, characterized both by the presence of large historical communities and minorities, and significant migration aims, and sheds new light on how sub-national units deal with migration.
