The rise of peace education both in scholarship and in practice has yielded numerous documents, websites, and publications with often divergent perspectives on what the field is, does, and means. The Encyclopedia of Peace Education provides a comprehensive overview of the scholarly developments in the field to date, so as to provide a common deminator for the various actors involved in advancing peace education internationally. Thus, this edited volume serves as an essential reference guide that traces the history and emergence of the field, highlights foundational concepts, contextualizes peace education practice across international and disciplinary borders, and suggests new directions for peace educators. From core conceptual perspectives to the moral and spiritual foundations of the field to the role of the United Nations, the Encyclopedia grounds peace education in a solid theoretical and practical framework through the writings of the field's most rewned scholars. This volume will target undergraduate and graduate students as well as scholars and practitioners working in international and n-governmental organizations in the field of peace education.
