Abstract EU citizenship has matured as an institution, owing to a number of important interventions by the European Court of Justice and legislative initiatives, such as the Citizenship Directive 2004/38/EC, which has recently entered into force. In this article, I critically examine minimalist and cosmopolitan conceptions of European citizenship and argue that once we dispense with the preoccupation of assigning primacy to a specific level of citizenship and establishing some kind of hierarchy among them, we can begin to address the questions and issues that really matter. Among these are the future governance of citizenship and the design of a more inclusive, multilayered and multicultural conception of citizenship. European citizenship entails a number of fruitful ideas for a more ambitious transition to a post-national tableau and can be the prototype for institutional experimentation on citizenship on a global scale.
