In recent years immigration and the integration of migrants and minorities have become politicised in public and policy debates in Britain, the rest of Europe and the United States. In such debates, migrants are commonly treated as objects of politics and spoken in terms of management, national interest, control and contention. This treatment has characterised not only policy makers and politicians but also many academics. Existing scholarly research on migrants as subjects of politics is limited and largely carried out through detached and structural approaches. These approaches have focused on the institutional environments in which mobilisations develop. They have, however, overlooked migrants’ conditions, experiences, subjectivities and practices as well as the focus of their engagement.This volume contributes to the study of migrants’ mobilisation through theoretically informed original empirical papers focusing on current forms and aspects of migrants and minorities practices of citizenship in an engaged and people-centred manner. In particular, the book addresses issues of change both in the forms assumed by migrants’ and minorities political engagements and in the transformations these engagements produce as well as exclusion-inclusion dynamics that migrants experience with regard to the political process and more generally.This book was previously published as a special issue of Ethnic and Racial Studies.
