As part of this treaty the French had guaranteed the Portuguese naval protection. In 1702, the English navy sailed close to Lisbon on the way to and from Cadiz, proving to the Portuguese that the French could not keep their promise. They soon began negotiations with the Grand Alliance about switching sides. There were actually two Methuen Treaties. Both were negotiated for England in Lisbon by John Methuen ( 1650–1706), who served as a member of

Each High Contracting Party further declares that no obligation be entered into, between itself and any other State or States, which might cause military damage to the other Party. This Treaty is concluded for the duration of twenty years and will be automatically extended for each successive period of five years unless either High Contracting Party declares its desire to terminate it by giving notice to the other High Contracting Party twelve months prior to the expiration of the Treaty. The Treaty will be subject to ratification
