Born in 12th-century France and bred for violence, Reynald de Chatillon was a young knight who joined the Second Crusade and rose through the ranks to become the preeminent figure in the crusader Kingdom of Jerusalem, chief foe of the Muslim leader Saladin, and one of the most reviled characters in Islamic history. In the West, Reynald has long been dismissed as a bloodthirsty maniac who brought disaster on his fellow crusaders. However, by using contemporary documents and original research, Jeffrey Lee overturns this popular perception and questions other prejudices about the crusades that underlie modern misunderstandings of the Middle East.
