One of the basic reasons for the outbreak of the hundred year´s war was a dynastic quarrel that originated when the conquest of England by William of Normandy created a state lying on both sides of the English Channel.

The immediate causes of the Hundred Years War were the dissatisfaction of Edward III of England with the no fulfillment by Philip VI of France of his pledges to restore a part of Guienne taken by Charles IV; the English attempts to control Flanders, an important market for English wool and a source of cloth; and Philip's support of Scotland against England.
