Thomas' new book, The Egyptian Crusade: Holy War on the Nile, is forthcoming with Yale and will appear in autumn 2026.
The story of the Egyptian crusade has the power to surprise and shock in equal measure. Along with a vivid sense of place of crusaders in the land of the pyramids, readers will gain a new understanding of the crusades, the nature of holy war in the Middle Ages, and the lives of the people who were at its centre.
