How does the enactment of citizenship politicise securitised sites? Security practices define citizenship by constituting the frontiers, exclusion zones, and limits of the political community. Security and Citizenship argues that security/citizenship practices are simultaneously governmental practices that secures the status of citizens and the authority of political apparatuses, and also a resource of counter-practices contesting the depoliticising effects of securitising. Through citizenship, conceptions of security and their effects become politically negotiated and contested. By bringing citizenship questions to bear upon security analysis, the book takes a case study and comparative approach to critically interrogate how political being is and can be constituted in relation to securitising practices. Security and Citizenship will be of interest to scholars of security studies and security politics, and international relations.
