The First Crusade: A New History (ISBN 0-743-22084-6) is a book by Thomas Asbridge, a University of London medieval history scholar. It aims to recapitulate the First Crusade. The book contains nine maps. Oxford University Press published the book in 2004.
According to the back of the book:
"Noted historian Thomas Asbridge offers a gripping account of a titanic three-year adventure filled with miraculous victories, greedy princes and barbarity on a vast scale. Beginning with the electrifying speech delivered by Pope Urban II in 1095, readers will follow the 100,000 men, women and children who take up his call. The siege of Nicea and the pivotal battle for Antioch, the single most important military engagement of the entire expedition, are featured here in vivid detail. Asbridge also describes the horrific Jerusalem massacre of 1099 when the crusaders, driven on by an intense religious devotion, unleashed an unholy wave of brutality, slaughtering thousands of Muslims, all in the name of Christianity.
"The First Crusade marked a watershed in relations between Islam and the West, a conflict that set these two world religions on a course toward deep-seated animosity and enduring enmity. The chilling reverbations of this earth-shattering clash still echo in this world today."
