This book presents a collection of new and updated essays on what has come to be known as the territorial explanation of war.

The book argues that a key both to peace and to war lies in understanding the role territory plays as a source of conflict and inter-group violence. Of all the issues that spark conflict, territorial disputes have the highest probability of escalating to war. War, however, is hardly inevitable; much depends on how territorial issues are handled. More importantly, settling territorial disputes and establishing mutually recognized boundaries can produce long periods of peace between neighbors, even if other salient issues arise. While territory is not the only cause of war and wars arise from other issues, territory is one of the main causes of war, and learning how to manage it, can, in principle, eliminate an entire class of wars.

This book will be of great interest to all students of war and conflict studies, causes of war and peace, international security and strategic studies.
