The Latin title Rex Catholicissimus, Anglicized as Most Catholic King or Most Catholic Majesty, was awarded by the Pope to the Sovereigns of Spain. It was first used by Pope Alexander VI in the papal bull Inter caetera in 1493.
The best-known example of this title is the Catholic Monarchs (Los Reyes Católicos), used solely in reference to Isabella I of Castile and Ferdinand II of Aragon.
Neither King Juan Carlos I nor Felipe VI have made use of the title, but they have not renounced it either.
