Most Faithful Majesty


Most Faithful Majesty was the style used by the Portuguese monarchs, from 1748 to 1910. The title is still attached to Portugal, as it was given to Portugal in the person of its sovereigns, and is still being used by the Holy See.
The sobriquet Most Faithful King was a title awarded by the Pope Benedict XIV – as spiritual head of the Catholic Church – in 1748, to King João V of Portugal and to his heirs.
The title Fidelissimus remains attached to monarchs descended from whoever received the original sobriquet, and to Portugal itself. The sobriquet can be awarded to either a king or a queen. The only European monarchy that has received the sobriquet was the now-defunct monarchy of Portugal.
