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.
France–United Kingdom relations
The English monarchy increasingly integrated with its subjects and turned to the English language wholeheartedly during the Hundred Years' War between 1337 and 1453. Though the war was in principle a mere dispute over territory, it drastically changed societies on both sides of the Channel. The English, although already politically united, for the first time found pride in their language and identity, while the French united politically.
