The Kings and Queens of Aragon are usually dated from Ramiro I's decisive split of his lands away from Navarre.

Patronilla's marriage to Ramon Berenguer IV of Barcelona unites Aragon and Barcelona.

Catherine's insanity is hushed up and she is effectively sidelined with her son James acting as regent until he can assume the crown himself. Catherine would die in 1708.

Catherine's two sons are little mourned and their cousin Peter, Count of Gévaudan is semi-elected to the throne as Alfonso lies dying.
