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
France was an ally of the Kingdom of Scotland as English kings had for some time tried to subjugate the area. In 1295, a treaty was signed between France and Scotland during the reign of Philip the Fair. Charles IV formally renewed the treaty in 1326, promising Scotland that France would support the Scots if England invaded their country. Similarly, France would have Scotland's support if its own kingdom was attacked. Edward could not succeed in his plans for Scotland if the Scots could count on French support.
