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.
Duchy of Aquitaine
Having suppressed a revolt in his new possession, Henry gave it to his son Richard. When Richard died in 1199, it reverted to Eleanor, and on her death five years later, it was absorbed into the English crown and henceforward followed the fortunes of the other English possessions in France, such as Normandy and Anjou, ultimately leading to the Hundred Years' War between the French and English crowns.
