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.
Joan of Arc
The Hundred Years' War had begun in 1337 as an inheritance dispute over the French throne, interspersed with occasional periods of relative peace. Nearly all the fighting had taken place in France, and the English army's use of "chevauchée" tactics (destructive "scorched earth" raids) had devastated the economy. The French population had not regained its former size prior to the Black Death of the mid-14th century, and its merchants were isolated from foreign markets. Prior to the appearance of Joan of Arc, the English had nearly achieved their goal of a dual monarchy under English control and the French army had not achieved any major victories for a generation. In the words of DeVries, "The kingdom of France was not even a shadow of its thirteenth-century prototype."
