How did almost a thousand years of intermittent conflict between Britain and France finally end at the beginning of the 20th century?

by iRoygbiv

The the Norman invasion was in 1066 and the Entente Cordial was in 1904. Between those two dates there was constant antagonism and either direct or indirect conflict between the two countries… the Hundred Years' War, the French Revolutionary Wars, the Seven Years' War, the American War of Independence, the Napoleonic Wars etc etc.

How did such a long history of conflict come to a permanent end in 1904?
