This open-access book offers a critical appraisal, at the cross-section of theory and practice, of concepts of integration at work in education in diverse geopolitical settings. With chapters written by experts based in Cyprus, Ethiopia, Germany, Mexico, Pakistan, the UK and the USA, the book includes discussion of regions of conflict, post-conflict and also non-conflict societies in which a cultural hegemony has developed strategies to "integrate" groups perceived as "other". The book challenges the idea of "integration" in education considering how it relates to inclusion and exclusion and considers the extent to which integration can be empirically studied or evaluated. By accommodating a diversity of voices and perspectives, the structure of this book critically questions the underlying hegemonic Global North-shaped assumptions that have informed the integration debate.
