This book examines how 'citizen art' practices perform new kinds of politics, as distinct from normative (status, participatory and cosmopolitan) models. It contends that at a time in which the conditions of citizenship have been radically altered (e.g., by the increased securitization and individuation of bodies etc.), there is an urgent drive for 'citizen art' to be enacted as a tool for assessing the 'hollowed out' conditions of citizenship. 'Citizen art', it shows, stands apart from other forms of Art by performing 'acts of citizenship' that reveal and transgress the limitations of state-centred citizenship regimes, whilst simultaneously enacting genuinely alternative modes of (non-statist) citizenship. This book explains how 'citizen art' can make citizenship manifest in ways that do not reify or valorize the nation-state, status rights, or cosmopolitan imaginaries. It shows instead that the outcomes of 'citizen art', such as the institutions of solidarity, assembly and interventions, reconfigure the 'tools' of politics in the act of 'doing politics' that, in turn, perform new and nascent modes of (non-statist) citizenship. This book offers a new formulation of 'citizen art' - one that is interrogated on both critical and material levels, and as such, that remodels the foundations on which citizenship is conceived, performed and instituted.
