Helen Irving, Professor Emerita, Sydney Law School, The University of Sydney, Australia

‘Focused on citizenship as legal status, Helen Irving meticulously excavates the complex past and present of allegiance in relation to the topic of citizenship. She shows us in detail how allegiance works, how it links to acquisition and loss of citizenship, and how we should think about it in relation to contested topics such as dual citizenship. Until now, there has been a gap in the literature of modern citizenship in relation to allegiance. Irving’s new book fills that gap.’

• Contents: Preface 1. Introduction: the origins and evolution of allegiance 2. Dual citizenship and ‘split allegiance’ 3. Naturalisation and transfer of allegiance 4. Swearing allegiance 5. Treason 6. Loss of citizenship 7. Buying citizenship 8. Conclusion: the citizenship bond Index
