As a child he was given his own suit of armor; at the age of sixteen, he helped defeat the French at Crécy. At Poitiers, in 1356, his victory over King John II of France forced the French into a humiliating surrender that marked the zenith of England’s dominance in the Hundred Years War. As lord of Aquitaine, he ruled a vast swathe of territory across the west and southwest of France, holding a magnificent court at Bordeaux that mesmerized the brave but unruly Gascon nobility and drew them like moths to the flame of his cause. He was Edward of Woodstock, eldest son of Edward III, and better known to posterity as “the Black Prince.” His military achievements captured the imagination of Europe: heralds and chroniclers called him “the flower of all chivalry” and “the embodiment of all valor.” But what was the true nature of the man behind the chivalric myth, and of the violent but pious world in which he lived?

Edward III lived through bloody and turbulent times. His father was deposed by his mother and her lover when he was still a teenager; a third of England's population was killed by the Black Death midway through his reign; and the intractable Hundred Years War with France began under his leadership. Yet Edward managed to rule England for fifty years, and was viewed as a paragon of kingship in the eyes of both his contemporaries and later generations. Venerated as the victor of Sluys and Crécy and the founder of the Order of the Garter, he was regarded with awe even by his enemies. But he lived too long, and was ultimately condemned to see thirty years of conquests reversed in less than five. In this gripping new account of Edward III's rise and fall, Jonathan Sumption introduces us to a fêted king who ended his life a heroic failure.
