Encompassing a long twelfth century, beginning with the Norman Conquest of England, and a short thirteenth, ending on the eve of the rebellion of the Welsh against Edward I in 1282, this book provides an integrated history of England, Ireland, Scotland, and Wales. In six chapters, leading experts compare and contrast experiences in different regions, focusing on key subjects such as the changing political and social structures; the reforms that affected the ecclesiastical landscape; cultural relationships; and the growth of a monetized economy. With an introduction and conclusion by Barbara Harvey, numerous maps and illustrations, a chronology, and a glossary of medieval terms, this book explores the interactions between the parts of the British Isles to provide an absorbing and incisive history of this period.
