* What is citizenship?* Is global citizenship possible?* Can cosmopolitanism provide an alternative to globalization?Citizenship in a Global Age provides a comprehensive and concise overview of the main debates on citizenship and the implications of globalization. It argues that citizenship is no longer defined by nationality and the nation state, but has become de-territorialized and fragmented into the separate discourses of rights, participation, responsibility and identity. Gerard Delanty claims that cosmopolitanism is increasingly becoming a significant force in the global world due to new expressions of cultural identity, civic ties, human rights, technological innovations, ecological sustainability and political mobilization. Citizenship is no longer exclusively about the struggle for social equality but has become a major site of battles over cultural identity and demands for the recognition of group difference. Delanty argues that globalization both threatens and supports cosmopolitan citizenship. Critical of the prospects for a global civil society, he defends the alternative idea of a more limited cosmopolitan public sphere as a basis for new kinds of citizenship that have emerged in a global age.
