Saintonge War
In English history, the ‘Hundred Years’ War’ refers to the 116-year period between 1337 – 1453. In some French accounts, that period of conflict is referred to as the ‘Second Hundred Years’ War’, the first embracing the period of upheaval following the change in the balance of power between the French and English thrones from 1159 to 1259 after Henry II of England married Eleanor of Aquitaine gaining many French territories in the process and achieving territorial superiority over the French Kingdom, until the Treaty of Paris (1259), in which the opposite became true. This period saw many conflicts and battles between the two kingdoms such as the Anglo-French War (1202–1214) or the Battle of Bouvines.
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.
