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.
Hundred Years' War
Several overwhelming English victories in the war—especially at Crécy, Poitiers, and Agincourt—raised the prospects of an ultimate English triumph, and convinced the English to continue pouring money and manpower into the war over many decades. However, the greater resources of the French monarchy prevented the English kings from ever completing the conquest of France. Starting in 1429, decisive French victories at Orléans, Patay, Formigny, and Castillon concluded the war in favour of the House of Valois, with England permanently losing most of its possessions on the continent.
