Joseph F. O'Callaghan is Professor Emeritus of Medieval History at Fordham University and author of numerous books. With The Last Crusade in the West, he concludes the magisterial history begun in his earlier The Gibraltar Crusade: Castile and the Battle for the Strait and Reconquest and Crusade in Medieval Spain, both available from the University of Pennsylvania Press.
Extremely useful book. The Last Crusade follows the thread of Crusade rhetoric and Castilian diplomatic and military operations through the century prior to the conquest of Granada; it is told with skill and erudition. -Speculum With this final volume in his ambitious trilogy, Joseph F. O'Callaghan offers the fullest history of the Reconquista that has ever been made available in English. His familiarity with the sources for medieval Iberian history rivals that of any other contemporary scholar. -Norman Housley, University of Leicester This book is the final volume of Joseph O'Callaghan's excellent trilogy on the crusading movement in medieval Spain. . . . [It] describes the final series of Castilian campaigns against the emirate of Granada, beginning in the mid-fourteenth century and culminating in the surrender of the city to Fernando and Isabel in 1492. . . . A good addition to the shelves of anyone interested in the crusades, Iberian history, or Christian-Muslim relations in the Mediterranean. -The Medieval Review
