The EU and Multilateral Security Governance studies the role of the EU in peace and security as a regional actor with global aspirations, in a context of challenged and changing multilateralism. The book examines and defines the pertinent concept of multilateral security governance, which, in spite of being more and more referred to, still needs further clarification and analysis. This book examines empirical evidence to develop further the understanding of ‘multilateral security governance’ and the EU’s role in it.
