"Tomaz Mastnak's provocative analysis of the roots of peacemaking in the Western world elucidates struggles for peace that took place in the high and late Middle Ages and shows their relevance to our contemporary thinking about peace. Mastnak traces the ways that eleventh-century peace movements, seeking to end violence among Christians, shaped not only power structures within Christendom but also the relationship of the Western Christian world to the world outside."--BOOK JACKET.
