The Gascon War, also known as the 1294–1303 Anglo-French War or the Guyenne War^[1] (French: Guerre de Guyenne), was a conflict between the kingdoms of France and England, which held many of its territories in nominal homage to France. It began with personal clashes between sailors in the English Channel in the early 1290s but became a widespread conflict over control of Edward I's Continental holdings after he refused a summons from Philip IV and renounced his state of vassalage. Most of the fighting occurred in the Duchy of Aquitaine, made up of the areas of Guyenne and Gascony. The first phase of the war lasted from 1294 to 1298, by which time Flanders had risen in revolt against France and Scotland against England. Hostilities concluded for a time under papal mediation, with the terms of the 1299 Treaty of Montreuil providing for the betrothal of Edward's son Prince Edward and Philip's daughter Isabella. The same year, Edward I also married Philip IV's sister Margaret. The second phase ran from 1300–03, until it was concluded by the 20 May 1303 Treaty of Paris, which reaffirmed the prince and princess's engagement. They were married in 1308.
