Conflict is at the heart of international relations and as we begin the new millennium it is occurring in new and vexing forms. This new edition looks at conflict both as an important subject in its own right and as a powerful lens through which to view international relations more generally. Charles Hauss provides a lively introduction to both theory and practice. He begins by tracing the three stages in most typologies of international conflict: origins, ending the fighting and reconciliation. A broad selection of case studies, covering many of the major conflicts the world has faced in the last ten years, provides the reader with material they can use to form their own judgements about the theories.
