Editing Arthur I, Duke of Brittany (section)

==Treaty of Le Goulet==
The [[Treaty of Le Goulet]] was signed by the kings John of England and Philip II of France in May 1200 and meant to settle once and for all the claims the [[Normans|Norman]] kings of England had as Norman dukes on French lands, including, at least for a time, [[Brittany]]. Under the terms of the treaty, Philip recognised John as King of England as heir of his brother Richard I and thus formally abandoned any support for Arthur. John, meanwhile, recognised Philip as the [[suzerain]] of continental possessions of the [[Angevin Empire]].

Philip had previously recognised John as suzerain of Anjou and the Duchy of Brittany, but with this he extorted 20,000 marks sterling in payment for recognition of John's sovereignty of Brittany.{{efn|The king of England bound himself in all ways as a vassal to his lord. He was required to obey summons, support his lord in war with troops or money, and to make payments of special feudal dues never before exacted from his lands.}}
