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.
History of France
The tensions between the Houses of Plantagenet and Capet climaxed during the so-called Hundred Years' War (actually several distinct wars over the period 1337 to 1453) when the Plantagenets claimed the throne of France from the Valois. This was also the time of the Black Death, as well as several civil wars. The French population suffered much from these wars. In 1420 by the Treaty of Troyes Henry V was made heir to Charles VI. Henry V failed to outlive Charles so it was Henry VI of England and France who consolidated the Dual-Monarchy of England and France.
