Edward III was 14 when he was crowned King and assumed government in his own
right in 1330. In 1337, Edward created the Duchy of Cornwall to provide the
heir to the throne with an income independent of the sovereign or the state.
An able soldier, and an inspiring leader, Edward founded the Order of the
Garter in 1348.
At the beginning of the Hundred Years War in 1337, actual campaigning
started when the King invaded France in 1339 and laid claim to the throne of
France. Following a sea victory at Sluys in 1340, Edward overran Brittany in
1342 and in 1346 he landed in Normandy, defeating the French King, Philip
VI, at the Battle of Crécy and his son Edward (the Black Prince) repeated
his success at Poitiers (1356).
By 1360 Edward controlled over a quarter of France. His successes
consolidated the support of the nobles, lessened criticism of the taxes, and
improved relations with Parliament. However, under the 1375 Treaty of Bruges
the French King, Charles V, reversed most of the English conquests; Calais
and a coastal strip near Bordeaux were Edward's only lasting gain.
Failure abroad provoked criticism at home. The Black Death plague outbreaks
of 1348-9, 1361-2 and 1369 inflicted severe social dislocation (the King
lost a daughter to the plague) and caused deflation; severe laws were
introduced to attempt to fix wages and prices. In 1376, the 'Good
Parliament' (which saw the election of the first Speaker to represent the
Commons) attacked the high taxes and criticized the King's advisers. The
ageing King withdrew to Windsor for the rest of his reign, eventually dying
at Sheen Palace, Surrey.
