Covering Portugal and Castile in the West to the Latin Kingdom of Jerusalem in the East, this collection focuses on Muslim minorities living in Christian lands during the high Middle Ages, and examines to what extent notions of religious tolerance influenced Muslim-Christian relations. The authors call into question the applicability of modern ideas of toleration to medieval social relations, investigating the situation instead from the standpoint of human experience within the two religious cultures. Whereas this study offers no evidence of an evolution of coherent policy concerning treatment of minorities in these Christian domains, it does reveal how religious ideas and communitarian traditions worked together to blunt the harsh realities of the relations between victors and vanquished.The chapters in this volume include "The Mudejars of Castile and Portugal in the Twelfth and Thirteenth Centuries" by Joseph F. O'Callaghan, "Muslims in the Thirteenth-Century Realms of Aragon: Interactions and Reaction" by Robert I. Burns, S.J., "The End of Muslim Sicily" by David S. H. Abulafia, "The Subjected Muslims of the Frankish Levant" by Benjamin Z. Kedar, and "The Papacy and the Muslim Frontier" by James M. Powell.Originally published in 1990.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.
