In this authoritative work, Jonathan Riley-Smith provides the definitive account of the Crusades: an account of the theology of violence behind the Crusades, the major Crusades, the experience of crusading, and the crusaders themselves. With a wealth of fascinating detail, Riley-Smith brings to life these stirring expeditions to the Holy Land and the politics and personalities behind them. This new edition includes revisions throughout as well as a new Preface and Afterword in which Jonathan Riley-Smith surveys recent developments in the field and examines responses to the Crusades in different periods, from the Romantics to the Islamic world today.
