Key Arguments: Edward III’s claim to the French throne was a major trigger for the Hundred Years’ War, but it built on preexisting Anglo-French hostility. English success at Poitiers came from superior tactical adaptation: defensive terrain, longbow use, and exploiting French disorganization. The French numerical advantage was undermined by poor coordination across multiple attack waves and confusion caused by retreating formations. The Black Death delayed major warfare by devastating populations and making sustained military campaigning difficult. King Jean II’s capture forced a costly ransom settlement that further strained France’s weakened economy and politics. Poitiers is historically important alongside Crécy and Agincourt as one of the war’s decisive engagements.
