God's War by Christopher Tyerman

A New History of the Crusades

A sweeping, tightly researched synthesis that reexamines the crusading movement from the late eleventh century onward, treating it as a complex, evolving phenomenon shaped by religious fervor, political ambition, social pressures and economic interests rather than a single, monolithic enterprise; it traces the motives and actions of popes, monarchs, knights, pilgrims and ordinary people, the interplay between Latin Christendom and Byzantine and Muslim worlds, the roles of military orders and propaganda, and the violence and consequences of long-term contact and conflict, while challenging older romantic or simplistic interpretations and emphasising nuance, contingency and the changing meanings and memories of crusading over time.
