The office of Marshal of the Kingdom of Portugal (Marechal do Reino de Portugal, sometimes Mariscal) was created by King Ferdinand I of Portugal in 1382, in the course of the reorganization of the higher offices of the army of the Kingdom of Portugal. The Marshal was directly subordinate to the Constable of Portugal (Condestável), being principally responsible for the high administrative matters, including the quartering of troops, supplies and other logistical matters.
Gonçalo Vasques de Azevedo was appointed the first Marshal of the Kingdom in 1382. The office then passed to his son-in-law, Gonçalo Vasques Coutinho, and was maintained within the Coutinho family (see Counts of Marialva) until the Iberian Union of 1580. After the 1640 restoration of Portugal, the office was resurrected by King João IV of Portugal and the Algarves, and maintained for a few more years.
