Five documentary witnesses preserved at the Archivo General de Simancas and dated from November 29 to December 2, 1483, allow us to follow the negotiation and then the implementation of an agreement between Francis II, Duke of Brittany, Ferdinand II of Aragon, and Isabella I of Castile. Bretaigne DAO publishes the references of the sources already found, what they actually establish, and the documents that still need to be located.
