The number of edited volumes covering issues of diversity, multiculturalism, and migrant integration has grown rapidly. Often, they are rather loose collections that cover only a single country or region. This volume deals with ethnic politics, migration, national minorities, nationalism, and conflict resolution in both developed and developing countries. Drawing what in some cases are fresh connections between these knotty topics across a range of contexts, the contributors manage collectively to achieve greater analytical coherence and depth than is found in many more narrowly focused edited works. Several of the chapters are valuable in their own right, moreover, such as Anthony Messina’s thoughtful essay on how to study migrant incorporation in Europe.Patrick R.
