In both popular memory and in their own histories, the Normans remain almost synonymous with conquest. In their relatively brief history, some of these Normans left a small duchy in northern France to fight with Empires, conquer kingdoms, and form new ruling dynasties. This book examines the explosive Norman encounters with the medieval Mediterranean, c. 1000-1250. It evaluates new evidence for conquest and communities, and offer new perspectives on the Normans' many meetings and adventures in history and memory. The contributions gathered here ask questions of politics, culture, society, and historical writing. How should we characterize the Normans' many personal, local, and interregional interactions in the Mediterranean? How were they remembered in writing in the years and centuries that followed their incursions? The book questions the idea of conquest as replacement, examining instead how human interactions created new nodes and networks that transformed the medieval Mediterranean. Through studies of the Normans and the communities who encountered them—across Iberia, the eastern Roman Empire, Lombard Italy, Islamic Sicily, and the Great Sea—the book explores macro- and micro-histories of conquest, its strategies and technologies, and how medieval people revised, rewrote, and remembered conquest.
