This volume describes the Frankish states of Outremer from the accession of King Baldwin I to the re-conquest of Jerusalem by Saladin. As Runciman says in his preface, 'The politics of the Moslem world in the early twelfth-century defy straightforward analysis, but they must be understood if we are to understand the establishment of the Crusader states and the later causes of the recovery of Islam … The main theme in this volume is warfare … I have followed the example of the old chroniclers, who knew their business; for war was the background to life in Outremer and the hazards of the battlefield often decided its destiny.
