What does recognition mean and how does the concept apply to the empirical study of international conflicts? This book provided some answers based on theoretical considerations as well as on empirical case studies of the origins of international conflict and terrorist violence. Drawing on these theoretical and empirical perspectives, I will formulate some testable hypotheses about recognition and the origins of war. In the first section, I will propose a definition of non-recognition and explain why the concept of recognition can be applied to interstate relations. In the second section, I will formulate some hypotheses about the link between non-recognition and the origins of war. In a final section, I will outline some methods to empirically investigate these hypotheses.
