The Hundred Years' War (1337-1453) was an intermittent conflict fought between England and France that started when king Edward III of England (r. 1327-1377) squabbled with Philip VI of France (r. 1328-1350) over feudal rights concerning Gascony and trade with the Low Countries. Edward also asserted that he was the rightful king of France and pressed this claim by winning great victories at the battles of Crécy (1346) and Poitiers (1356). In 1360, Edward renounced his claim to the French throne in return for lordship over a quarter of France. The war then continued as each side attempted to control north and southwest France. After Charles V of France (r. 1364-1380) steadily regained much of the lands lost since the war began, there was a period of peace when Richard II of England (r. 1377-1399) married the daughter of Charles VI of France (r. 1380-1422). Henry V of England (r. 1413-1422), eager to win glory, booty, and legitimacy for his own reign, then reignited the conflict with his stunning victory at the Battle of Agincourt in 1415 which enabled him to be nominated the heir to the French throne. After Henry V's untimely death and the ineffectual rule of Henry VI of England (r. 1422-61 & 1470-71), Charles VII of France (r. 1422-1461) retook the initiative. With help from such figures as the Duke of Burgundy and Joan of Arc (1412-1431), Charles won the war and managed to remove the English from all French territory except Calais. The causes of the Hundred Years' War and reasons for its continuation include: The seizure of English-held Gascony (Aquitaine, south-west France) by Philip VI of France. The claim by the English king Edward III to be the rightful king of France. The expedition of Edward III to take by force territories in France, protect international trade and win booty and estates for his nobles. The ambition of Charles V of France to remove the English from France's feudal territories. The descent into madness of Charles VI of France and the debilitating infighting amongst the French nobility. The ambition of Henry V of England to legitimise his reign in England and make himself the king of France through conquest. The determination of the Dauphin, future King Charles VII of France (r. 1422-1461), to regain his birthright and unify all of France.
