The Hundred Year War was a conflict between England and France over succession in the years from 1337 to 1453, towards the end of this war when England lost its claims to French territory. This loss had a number of effects; the French language was used in the higher levels of English society. The hostility toward the French after the wars caused the language to be seen as that of the enemy. The introduction of the English language was a way of establishing a national identity. From, this English started to use in diplomatic papers and in legal documents where French had been used. The end of the hundred year war, which was not a continuous war, it played out intermittently from 1337 to 1453 which was over the succession of the French throne.
