hundred years war definition
The Hundred Years' War was a time of rapid military evolution. Weapons, tactics, army structure and the social meaning of war all changed, partly in response to the war's costs, partly through advancement in technology and partly through lessons that warfare taught.efore the Hundred Years' War, heavy cavalry (knights) was considered the most powerful unit in an army, but by the war's end, this belief had shifted. The heavy horse was increasingly negated by the use of the longbow (and, later, another long-distance weapon: firearms).
