The Hundred Years' War, which lasted from 1337 to 1453, was the backdrop to their pillaging. The Hundred Years' War was fought between two royal families over control of the French throne: the Plantagenets from England, and the House of Valois from France. The War, which is divided into three stages - the Edwardian War (1337-1360), the Caroline War (1369-1389), and the Lancastrian War (1415-1429) - saw the development of new tactics and weaponry that revolutionised warfare during that time period.
Treaty of Paris (1303)
The Treaty of Paris was signed on 20 May 1303 between Philip IV of France and Edward I of England. Based on the terms of the treaty, Gascony was restored to England from France, thus setting the stage for the Hundred Years' War (1337-1453). Moreover, it was confirmed that Philip's daughter would marry Edward's son (the later Edward II of England), as already agreed in the Treaty of Montreuil (1299).
