<P> The Hundred Years' War almost resumed in 1474, when the duke Charles of Burgundy, counting on English support, took up arms against Louis XI . Louis managed to isolate the Burgundians by buying Edward IV of England off with a large cash sum and an annual pension, in the Treaty of Picquigny (1475). The treaty formally ended the Hundred Years' War with Edward renouncing his claim to the throne of France . However, future Kings of England (and later of Great Britain) continued to claim the title until 1803, when they were dropped in deference to the exiled Count of Provence, titular King Louis XVIII, who was living in England after the French Revolution . </P> <P> The French victory marked the end of a long period of instability that had started with the Norman Conquest (1066), when William the Conqueror added "King of England" to his titles, becoming both the vassal to (as Duke of Normandy) and the equal of (as king of England) the king of France . </P> <P> When the war ended, England was bereft of its Continental possessions, leaving it with only Calais on the continent . The war destroyed the English dream of a joint monarchy and led to the rejection in England of all things French, but the French language in England, which had served as the language of the ruling classes and commerce there from the time of the Norman conquest, left many vestiges in English vocabulary . English became the official language in 1362 and French was no longer used for teaching from 1385 . </P> <P> National feeling that emerged from the war unified both France and England further . Despite the devastation on its soil, the Hundred Years' War accelerated the process of transforming France from a feudal monarchy to a centralised state . In England the political and financial troubles which emerged from the defeat was one major cause of the War of the Roses (1455--1487). </P>
