This book provides a broad overview of what peace research is all about by an author who has been involved in the field for more than half a century. Among other things it gives a unique review of how peace research emerged in Sweden as the author was a key actor in the most crucial events during this formative period. The book also portrays how the discipline has grown from an initial focus on “alternatives to war” to the comprehensive study of the many dimensions of a “lasting and positive peace”. The author's own work covers causes of war, sanctions, conflict resolution, conflict data, mediation, and quality peace. They demonstrate the range of topics that have to be understood for a peace with quality. This is exemplified by some of the author's writings specifically selected for this volume plus a few ones original to it. Some accounts of the author's involvements in actual peace processes in the 1990s are also included.
