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.
Gascon campaign (1294–1303)
The Gascon campaign of 1294 to 1303 was a military conflict between English and French forces over the Duchy of Aquitaine, including the Duchy of Gascony. The Duchy of Aquitaine was held in fief by King Edward I of England as a vassal of King Philip IV of France. Starting with a fishing fleet dispute and then naval warfare, the conflict escalated to open warfare between the two countries. In spite of a French military victory on the ground, the war ended when the Treaty of Paris was signed in 1303, which restored the status quo. The war was a premise to future tensions between the two nations culminating in the Hundred Years' War.
