Sir Steven Runciman’s three volume *A History of the Crusades* , is one of the great classics of English historical writing. Volume I deals with the First Crusade and the foundation of the Kingdom of Jerusalem. Volume II describes the Frankish states of Outremer from the accession of King Baldwin I to the re-conquest of Jerusalem by Saladin, and in the third volume, Sir Steven examines the revival of the Frankish kingdom from the time of the Third Crusade until its collapse a century later. The interwoven themes of the book include: Christiandom, the replacement of the cultured Ayubites by the less sympathetic Mameluks as leader of the Moslem world, and the coming of the Mongols. He includes a chapter on architecture and the arts, and an epilogue on the last manifestations of the Crusading spirit.
