Throughout the eleventh and twelfth centuries the Normans – ‘that most unbridled People’ – spread across Europe and the Mediterranean as conquerors, settlers, crusaders, and pilgrims. Borders, be they geographical, intellectual, diplomatic, legal, spiritual, or temporal, provide an especially arresting way of examining Norman activities and the lands in which they dwelt. It is the intention of this conference to consider these borders – creations, disruptions, and developments, and their roles, significance, and influence – to gain new-found insight into the Normans and their World.
