Book excerpt: The story of the First Crusade, as witnessed by contemporary writers 'O day so ardently desired! O time of times the most memorable! O deed before all other deeds!' The fall of Jerusalem in the summer of 1099 to an exhausted and starving army of western European soldiers was one of the most extraordinary events of the Middle Ages. It was both the climax of a great wave of visionary Christian fervour and the beginning of what proved to be a futile and abortive attempt to implant a new European kingdom of heaven in an overwhelmingly Muslim world. This remarkable collection brings together a wide variety of contemporary accounts of the First Crusade, including Pope Urban II's initial call to arms of 1095, as well as the first-hand writings of priests, knights, a Jewish pilgrim, a destitute noblewoman, an Iraqi poet and the historian Anna Comnena. Together they provide a vivid and nuanced picture of the First Crusade and the people who were swept up in it. Edited with an introduction and notes by Christopher Tyerman
