Middle Ages
Throughout the 14th century, French kings sought to expand their influence at the expense of the territorial holdings of the nobility. They ran into difficulties when attempting to confiscate the holdings of the English kings in southern France, leading to the Hundred Years' War, waged from 1337 to 1453. Early in the war the English under Edward III (r. 1327–77) and his son Edward, the Black Prince (d. 1376), won the battles of Crécy and Poitiers, captured the city of Calais, and won control of much of France. The resulting stresses almost caused the disintegration of the French kingdom during the early years of the war. In the early 15th century, France again came close to dissolving, but in the late 1420s the military successes of Joan of Arc (d. 1431) led to the victory of the French and the capture of the last English possessions in southern France in 1453. The price was high, as the population of France at the end of the Wars was likely half what it had been at the start of the conflict. Conversely, the Wars had a positive effect on English national identity, doing much to fuse the various local identities into a national English ideal. The conflict with France also helped create a national culture in England separate from French culture, which had previously been the dominant influence. The dominance of the English longbow began during early stages of the Hundred Years' War, and cannon appeared on the battlefield at Crécy in 1346.
Early modern France
After the Hundred Years' War (1337–1453) and the Treaty of Picquigny (1475) – its official end date – in 1492 and 1493, Charles VIII of France signed three additional treaties with Henry VII of England, Maximilian I of Habsburg, and Ferdinand II of Aragon respectively at Étaples (1492), Senlis (1493) and in Barcelona (1493). As the 15th century drew to a close, French kings could take confidence in the fact that England had been mostly driven from their territory and so they could now embark on an expansionist foreign policy. The invasion of Italy by Charles VIII in 1494 began 62 years of war with the Habsburgs (the Italian Wars).
Despite the beginnings of rapid demographic and economic recovery after the Black Death of the 14th century, the gains of the previous half-century were to be jeopardised by a further protracted series of conflicts, the Italian Wars (1494–1559), where French efforts to gain dominance ended in the increased power of the Habsburg Holy Roman Emperors of Germany.
