The period of intermittent fighting between England and France that started in 1337 and ended in 1453 is known as THE HUNDRED YEARS WAR.

The Hundred Years War was a conflict between the Kingdom of England and the Kingdom of France which lasted, with several interruptions, one hundred and sixteen years, from 1337 to 1453. It ended with the expulsion of the British from all the continental territories with the exception for the town of Calais, conquered by the French only in 1558. In the process of formation of the French unitary state, already under the first Capetian kings, it represented a long pause, but at its conclusion France had substantially reached the modern geopolitical order.

The extraordinary importance of the Hundred Years War, as regards the history of Europe as a whole, is highlighted by the fact that its end (1453, the year that saw the fall of Constantinople) is one of the dates conventionally posed by historiography modernization at the end of the European Middle Ages.
