The Pact of Cartagena was an exchange of notes rather than a full alliance, but it linked Spanish interests to Anglo-French diplomacy. Its parties declared an intention to preserve the western Mediterranean and Atlantic status quo, especially their island and coastal possessions. The discussion considers how Spanish participation in a European war might have altered the balance of manpower and access. It is a reminder that the pre-1914 diplomatic map had more possible branches than the eventual war suggests.
