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.
France–United Kingdom relations
The English monarchy increasingly integrated with its subjects and turned to the English language wholeheartedly during the Hundred Years' War between 1337 and 1453. Though the war was in principle a mere dispute over territory, it drastically changed societies on both sides of the Channel. The English, although already politically united, for the first time found pride in their language and identity, while the French united politically.
