The cessation of military confrontations rarely coincides with the end of war. Legal and political matters continue after the last shot has been fired, civilians driven from their homes try to rebuild their houses and their lives, veterans need to adapt to their new role in civil society, and the struggle to define the history and the significance of past events only begins. In recent years, in particular, the changes in the character of contemporary warfare have created uncertainties across different disciplines about how to identify and conceptualise the end of war. It is therefore an opportune moment to examine how wars end from a multidisciplinary perspective that combines enquiries into the politics of war, the laws of war and the military and intellectual history of war. This approach enables both an understanding of how ‘the end’ as a concept informs the understanding of war in international relations, in international law and in history and a reconsideration of the nature of scientific method in the field of war studies as such.
