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.
Invasions of the British Isles
England was spared invasion during the Hundred Years' War against France and Castile, but it was plagued by 32 years (1455–1487) of civil wars known as the Wars of the Roses. The Lancastrian branch of the House of Plantagenet, which had overthrown the direct royal line in 1399, was embroiled in fighting against the Yorkist wing of the dynasty.
