Accessing the legitimation process of security regionalism: African Union and European Union as case studies


The GEM PhD Erasmus Mundus is my third academic experience abroad. I chose GEM not only because of the academic and financial support and the qualified universities, but also because of the possibility to interact and exchange ideas on a full international level. Ever since my application was selected, I’ve been given all the necessary support to start my research. It’s been a pleasure to be part of it, but also a great responsibility.

Description of research work

The research aims to shed light on the normative underpinnings of security regionalism. As regional security initiatives flourish around the world, we ask how does the legitimation process of regional security organizations take place, who are the legitimizing actors, what are the arguments put forward by them, and who constitutes the relevant audiences granting legitimacy.
