This article argues that a central reason for Turkey’s EU stalemate can be located in domestic debates over what constitutes an appropriate definition of Turkish national identity.

Underlining that identities have an inherent capacity for change, however, the article argues that Turkey’s seemingly ossified “Us v. Them” relations at both the domestic and international levels contain the potential for reconciliation.
