On September 4th, 5th and 6th 2013, UNU-GCM hosted a workshop on ‘Non-citizen’ship at the 10th series of MANCEPT Workshops on Political Theory in Manchester, UK, an important international forum for the development of new areas in Political Theory research. Alongside a series of interesting and engaging papers, offering both case studies and theoretical analyses, there was intense debate. It was excellent to have a range of perspectives represented, and in the final round-table session, the group have agreed to continue to work together to develop this emerging area in Political Theory. Citizenship has long been a crucial core concept in the development of Political Theory, with work being done to explore the nature of the status from a variety of angles, and in a variety of forms. Non-citizenship in its various forms is usually examined merely as the deprivation of citizenship. However, as was agreed in the workshop, the status of the ‘non-citizen’ needs to be understood as more than the mere negation of citizenship.
