Edward I―one of the outstanding monarchs of the English Middle Ages―pioneered legal and parliamentary change in England, conquered Wales, and came close to conquering Scotland. A major player in European diplomacy and war, he acted as peacemaker during the 1280s but became involved in a bitter war with Philip IV a decade later. This book is the definitive account of a remarkable king and his long and significant reign. Widely praised when it was first published in 1988, it is now reissued with a new introduction and updated bibliographic guide.
