Following the Treaty of Paris of 1259, Edward I, as duke of Aquitaine, held Gascony as a feudal subject of the King of France. Following Anglo-French naval rivalries in 1293, however, Philip IV of France pressed his claims as Edward's feudal overlord in Gascony. This was essentially the same action as Edward himself had undertaken previously in Wales and Scotland, but he failed to recognize the French position and rejected his feudal status in France. In 1294 he began a war with his Flemish allies against the French king.
The Welsh rebellion of 1294-5 and the English invasion of Scotland in 1296 (following Scotland's alliance with France) created a war on three fronts, which drained the finances of the country and threatened to overstretch Edward's military resources. Developments in the war in Flanders forced a truce between Edward and Philip in the autumn of 1297, and this alone saved Gascony from further destruction. This image, drawn at the time of the truce, clearly indicates the hostility and mistrust between both monarchs. In 1303, Pope Boniface VIII mediated a peace treaty that overlooked the legality of the respective campaigns of both kings in Scotland and Flanders, and left both free to press their feudal claims in their border regions.
