Battle of Agincourt
England's claims on French soil were solidified by military might; Agincourt paved the way for the Treaty of Troyes, elevating Henry V to regent and heir to the French throne. The English victory provided the Lancastrian dynasty with immense domestic prestige, strengthening Henry V's position and facilitating the raising of resources for future campaigns. France lost virtually its entire military and political leadership class; the deaths of three dukes, nine counts, and thousands of knights created a generational command vacuum. Central authority collapsed; the civil war between the Burgundian and Armagnac factions reignited, leaving France vulnerable and paving the way for the English invasion that would last until 1420.

The longbow's effectiveness became entrenched as a force multiplier in English military doctrine, setting the stage for subsequent victories. The French feudal army suffered heavy losses, severely damaging the military prestige of the nobility and undermining monarchical authority. The English presence in northern France became permanent, with Calais remaining under English control for over two centuries.

England, under Henry V, captured extensive territories in Normandy and northern France, securing legal standing for its claim to the French throne. The Treaty of Troyes made Henry V regent and heir to France, extending English influence to Paris. France recovered through national resistance inspired by Joan of Arc; artillery and professional army reforms gradually pushed the English back. The French recaptured Gascony at the Battle of Castillon, leaving only Calais to the English; the Hundred Years' War effectively ended.
Read analysisBattle of Poitiers
England gained a massive diplomatic and economic advantage by capturing King John II, leading to the Treaty of Brétigny and substantial territorial gains. The English tactical dominance and the effectiveness of the longbow left a lasting impression on military doctrine, hastening the decline of feudal heavy cavalry. France, burdened by the king's ransom and loss of central authority, descended into internal strife, including the Jacquerie peasant revolt. The prestige of the French feudal army was shattered, forcing urgent military reforms; however, in the short term, the loss of territory and morale was catastrophic.

France expelled the English almost completely from continental Europe, securing territorial integrity and consolidating national identity. The French monarchy strengthened central authority, reducing feudal fragmentation and accelerating the transition to a modern state structure. England lost all its territories in France except Calais, forfeiting political and military influence on the continent and forced to become an island power.
