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.
Late Middle Ages
From 1337, England's attention was largely directed towards France in the Hundred Years' War. Henry V's victory at the Battle of Agincourt in 1415 briefly paved the way for a unification of the two kingdoms, but his son Henry VI soon squandered all previous gains. The loss of France led to discontent at home. Soon after the end of the war in 1453, the dynastic struggles of the Wars of the Roses (c. 1455–1485) began, involving the rival dynasties of the House of Lancaster and House of York.
