Sir Steven Runciman's three volume A History of the Crusades, one of the great classics of English historical writing, is now being reissued. In this final volume, Runciman examines the revival of the Frankish kingdom at 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.
