Chief of the King's Guard (Portugal and Castile)

The Chief of the King's Guard, King's Chief Guard, or Chief of the King's Corps, (guarda-mor do rei, or guarda-mor do Corpo do Rei in Portuguese) was an officer of the Crown of Castile and of the Portuguese Royal Family whose function was to protect the monarch and command his guard. == History == Some authors, when speaking of this position, state that it was more "honorific than effective", although Jaime de Salazar y Acha points out that this may have been the case during the last period of the Late Middle Ages, but not in its beginnings, since in the first instance the king's security was in the hands of his ensign, but the latter in turn would delegate this responsibility to the officer of lower rank who would possibly, over the centuries, evolve into, in the opinion of this historian, the officer known as the Chief of the King's Guard.
