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.
Second Hundred Years' War
The series of wars began with the accession of the Dutch William III as King of England in the Revolution of 1688. His predecessors the Stuarts had sought friendly terms with Louis XIV: James I and Charles I, both Protestants, had avoided involvement as much as possible in the Thirty Years' War, while Charles II and the Catholic convert James II had even actively supported Louis XIV in his War against the Dutch Republic. William III, however, sought to oppose Louis XIV's Catholic regime and styled himself as a Protestant champion. Tensions continued in the following decades, during which France protected Jacobites who sought to overthrow the later Stuarts and, after 1715, the Hanoverians.
