The European Security Strategy (ESS) from 2003 was a security strategy that was based on confidence and hope. It would make the EU an active and reliable global player taking a greater role in the world. The global landscape has inevitably changed since 2003 with new challenges coming across for example increased globalization, shifting power exposing different values, terrorism and organized crime and climate changes. To meet the new global landscape the European Union Global Strategy (EUGS) entered in 2016 with the mission to revitalize the EU ́s role and adapt a new international landscape. The strategy was set to (re)define its role and identity to avoid an existential crisis for the European Union. The study seeks to examine EU strategic culture by means of analysis of the security strategies ESS and EUGS if a strategic culture can be discerned and what theoretical features such a culture has. The thesis is based on a qualitaitve text analysis in order to understand the nature of an EU strategic culture followed by a qualitiaitve content analysis that works as an analytical tool and framework to examine the concept of strategic culture in ESS and EUGS. There is evidence of an EU strategic culture in the ESS and EUGS security documents. The four norms of strategic culture are represented according to Christoph O. Meyer’s concept of strategic culture but in different ways in ESS and EUGS. In ESS, EU strategic culture is about liberalism; it underlines the importance of international institutions, cooperation and human rights. In EUGS, EU strategic culture is characterized by the English School emphasizing interest, responsibility and international society in terms of common institutions and citizens.
