First full-length survey of the fluid relationship between these two areas at a time of rapid change. This book provides the first comprehensive analysis of the development of northern England and southern Scotland in the formative era of the twelfth and thirteenth centuries. How did "middle Britain" come to be divided between twoseparate unitary kingdoms called "England" and "Scotland"? How, and how differently, was government exercised and experienced? How did people identify themselves by their languages and naming practices? What major themes can be detected in the development of ecclesiastical structures and religious culture? What can be learned about the rural and the emerging urban environments in terms of lordly exploitation and control, settlement patterns and how the landscape itself evolved? These are among the key questions addressed by the contributors, who bring to bear multi-faceted approaches to medieval "middle Britain". Above all, by pursuing similarities and differences from a comparative "transnational" perspective it becomes clearer how the "old" interacted with the "new", what was exceptional and what was not, and how far the histories of northern England and southern Scotland point to common or not so commonfoundations and trajectories.
