Michael Prestwich's study of Edward I, first published in 1988 and now reissued with a new introduction and updated bibliographic guide, is the definitive full-length account of one of the leading monarchs of the Middle Ages. A king who pioneered legal and parliamentary change, conquered Wales and came close to conquering Scotland, Edward I presents many contradictions. A pious man who built his reputation during the greatest chivalric adventure of the time, the Crusade, he quarrelled with his archbishops. 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.
