Edward III (1312–1377)

King of England from 1327, son of Edward II. He assumed the government in 1330 from his mother, through whom in 1337 he laid claim to the French throne and thus began the Hundred Years' War. Edward was the victor of Halidon Hill in 1333, Sluys in 1340, Crécy in 1346, and at the siege of Calais 1346–47, and created the Order of the Garter. He was succeeded by his grandson Richard II.

Edward's early experience was against the Scots, including the disastrous Weardale campaign in 1327. Forcing them to battle outside Berwick at Halidon Hill, he used a combination of dismounted men-at-arms and archers to crush the Scots. Apart from the naval victory of Sluys his initial campaigns against France were expensive and inconclusive. Resorting to chevauchée (raids through enemy territory), he scored a stunning victory at the Battle of Crécy, which delivered the crucial bridgehead of Calais into English hands. Due to the military success of his son Edward of Woodstock (Edward the Black Prince) at the Battle of Poitiers in 1356 and in later campaigns, Edward achieved the favourable Treaty of Brétigny in 1360. He gave up personal command in the latter part of his reign. An inspiring leader, his Order of the Garter was a chivalric club designed to bind his military nobility to him. The Order and its codes of chivalry were widely imitated.

At age 18 Edward imprisoned his mother Isabella of France and executed her lover Roger de Mortimer. In 1360 he surrendered his claim to the French throne, but the war resumed in 1369, and his son John of Gaunt dominated the government in his later years.
