The religious histories of Christian and Muslim countries in Europe and Western Asia are often treated in isolation from one another. This can lead to a limited and simplistic understanding of the international and interreligious interactions currently taking place. This edited collection brings these national and religious narratives into conversation with each other, helping readers to formulate a more sophisticated comprehension of the social and cultural factors involved in the tolerance and intolerance that has taken place in these areas, and continues today. Part One of this volume examines the history of relations between people of different Christian confessions in western and central Europe. Part Two then looks at the relations between Western and Eastern Orthodox Christianity, Islam and Judaism in the vast area that extends around the Mediterranean from the Iberian Peninsula to western Asia. Each Part ends with a Conclusion that considers the wider implications of the preceding essays and points the way toward future research. Bringing together scholars from Asia, the Middle East, Europe, and America this volume embodies an international collaboration of unusual range. Its comparative approach will be of interest to scholars of Religion and History, particularly those with an emphasis on interreligious relations and religious tolerance.
