How long was the hundred years war?

The hundred years' War began in 1337 and continued for more than a century. It was not a single war but a series of skirmishes between England and France. It began when the English tried to dominate France,and the French in turn tried to confiscate lands occupied by the English.
The English invaded France and won a great battle at Crecy. The British archers with their longbows defeated a much larger army of knights, marking the beginning of the end for mounted nights. Further battles followed, but in 1396 Richard II of England married the daughter of Charles VI of France, establishing a 20 year truce that finally ended the fighting
