This book re-examines the relationship between language and national identity. Unlike many previous studies, it employs a comparative approach: France and Sweden have been chosen as case studies both for their similarities (e.g. both are member states of the European Union) as well as their important differences (e.g. France subscribes in principle to a civic model of national identity, whereas the basis of Swedish identity is undeniably ethnic). It is precisely differences such as these which allow for a more comprehensive understanding of the ethnolinguistic implications of some of the major challenges currently facing France, Sweden and other European countries: regionalism, immigration, European integration and globalization.
