Did the Crusades trigger significant intellectual activity? To what extent and in what ways did the Latin residents of the Crusader states acquire knowledge from Muslims and Eastern Christians? And how were the Crusader states influenced by the intellectual developments which characterized the West in the twelfth and thirteenth centuries? This book is the first to examine these questions systematically using the complete body of evidence from one major urban centre: Acre. It reveals that Acre contained a significant number of people who engaged in learned activities, as well as the existence of study centres housed within the city. This volume also seeks to reconstruct the discourse that flowed across four major fields of learning: language and translation, jurisprudence, the study of Islam and theological exchanges with Eastern Christians. The result is an unprecedentedly rich portrait of a hitherto neglected intellectual centre on the eastern shores of the medieval Mediterranean.
