Eleanor was still betrothed to the king of Aragon when the succession arrangement was made, so Edward I knowingly accepted the possibility of heirs with a strong Spanish connection. Warner interprets that choice as evidence that he respected his daughters' personalities and capabilities. The marriage match connects diplomacy with a practical judgment about who could govern England. The scenario never materialized because Edward of Caernarfon survived, Edward I fathered two more sons, and Edward II later had legitimate male heirs.
