This volume provides a readable and authoritative account of the history of the British Isles from the Norman Conquest of England, to the eve of the Welsh against Edward I in 1282 . At the beginning of the period, much of Britain belonged, as did Ireland, to the Vikings. The transformation ofthe archipelago by the end of this period is explored and explained in this volume. Six sharply focused chapters consider the fundamental changes that occurred in this period: the changing political and social structure and the adaptability of the aristocracy instrumental in these changes; thereforms that affected the ecclesiastical landscape; and the effects on economic life of the growth of a monetised economy. The influence of the natural environment and communications on life in medieval times are discussed in the Introduction. The approach is comparative, bringing out both the sharpcontrasts between the experience of the several parts of the British Isles and the similarities. With chapters contributed by a team of experts, Harvey explores the interactions between the parts of the British Isles to provide a clear and incisive history of this fascinating period.
