Question: how did the hundred years war marked the end of the feudal age in europe

title: Hundred Years' War
text: The war owes its historical significance to multiple factors . By its end , feudal armies had been largely replaced by professional troops , and aristocratic dominance had yielded to a democratisation of the manpower and weapons of armies . Although primarily a dynastic conflict , the war gave impetus to ideas of French and English nationalism . The wider introduction of weapons and tactics supplanted the feudal armies where heavy cavalry had dominated , and artillery became important . The war precipitated the creation of the first standing armies in Western Europe since the time of the Western Roman Empire and thus helping to change their role in warfare . With respect to the belligerents , in France , civil wars , deadly epidemics , famines , and bandit free - companies of mercenaries reduced the population drastically . English political forces over time came to oppose the costly venture . The dissatisfaction of English nobles , resulting from the loss of their continental landholdings , became a factor leading to the civil wars known as the Wars of the Roses ( 1455 -- 1487 ) .
