Following a poststructuralist theorising of identity in international relations, which argues that identity is relationally and discursively constructed through foreign policy, this article attempts to analyse the way in which the European Commission discursively constructs European identit(ies) in its relations with Turkey around the theme of ‘security’. The study utilises the methodological tools of critical discourse analysis in analysing the speeches and field interviews conducted with European Commission officials, in examining the way in which they construct ‘Europe’ in relation to the security implications of Turkish accession. The article’s findings challenge the argument that Europe is moving beyond the modern state to resemble a postmodern order, and problematises the designation of the Commission as a ‘cosmopolitan’ actor in EU enlargement policy.
