This work investigates the transformation of the English state and the nature of royal authority during the reigns of Edward I, Edward II, and Edward III. Michael Prestwich, a distinguished historian of the medieval period, utilizes extensive archival research and administrative records to analyze how these three monarchs navigated the pressures of war, parliamentary development, and social change. The book argues that the century between 1272 and 1377 was a critical period of institutional evolution that defined the English monarchy's relationship with its subjects and its neighbors.
