It takes a bold thinker to introduce a new term into the thicket of contemporary discussions of citizenship, migration and belonging. Tendayi Bloom does this with her ambitious concept of noncitzenism. She presents noncitizenship as a unifying analytic category that describes a particular relationship between individuals and States. Her claim is that the relationship deserves attention because of its special consequences for the rights of affected individuals, irrespective of their particular type of noncitizenship. Cogently argued and lucidly written, this impressive book is both a valuable addition to the literature on one of the major political challenges of our times, and a stimulating provocation for constituencies actively engaged in contesting the many injustices it describes. Jacqueline Bhabha, Harvard University, USA By documenting critical social movements this book illustrates how the rights of noncitizens are being constituted as a site of political struggle. It is a brilliant book that restores political agency to noncitizens in (liberal) theory – something that states resist in (illiberal) practices. Engin Isin, Queen Mary University of London, UK This book is a timely challenge to ‘methodological citizenism’ – the assumption that all political thinking has to be structured around citizenship. Against this, it poses the idea of noncitizenship, rather than non-citizenship. Drawing on a wide range of resources, it points the way forward, offering a vision of what liberal theory and practice could look like if they were to break out of the state-citizen relationship. And it stands as an urgent warning that, if they are to remain relevant to the project of social justice, then they must embrace the category of the noncitizen as an essential part of the liberal framework. It is essential reading for anybody concerned with the contradictions of national membership and global justice. Phillip Cole, University of the West of England, UK.
