Interwar European majority-minority questions have been predominantly discussed in the context of the East until now. This volume challenges that geographical emphasis by examining both Eastern and Western European experiences. It thus lays the foundation for a new comparative international history of the relations between national majorities and minorities in Europe after the Great War. Building on the assumption that nationalist conflicts are based on the dynamic interaction of multiple actors, this book brings together different perspectives and methodological approaches (political, social and transnational) to provide a comprehensive account of minority questions between the two World Wars.With contributions from leading academics and emerging scholars based in the UK, the USA, Austria, Switzerland, Spain, Ireland, Hungary and Poland, Sovereignty, Nationalism, and the Quest for Homogeneity in Interwar Europe is a wide-ranging study which is firmly anchored in the history of the transition from empires to nation-states as well as in the history of human rights and the nation-state.
