The creation of the first Military Staff in Spain dates back to 1801 when on the occasion of the
War of Spain and France against Portugal, an army was created under the command of
Godoy, which included a special structure called the General Staff, also called the General Staff of the Armies in Operations. On June 9, 1810 is constituted for the first time in Spain the Body of General Staff, separated completely from the other Armies branches, following their top officials different military careers.
General Blake was its first chief. Once the
War of Independence was over, by Royal Order of June 27, 1814,
Ferdinand VII suppressed the General Staff Body. In 1820 it was created for the second time, but its existence was short, and in 1823 it disappeared again. In 1837, experience had shown the ineffectiveness of all the decisions that had been taken to replace the Body of General Staff and the General Staff was again established for the proper functioning of the Army. Its new organization was approved on January 1, 1838 and in front of it was a director-general. In 1904, the Central Staff of the Army (EMCE) appeared, which was suppressed in 1912 and returned to the previous organization, the General Staff Body; the EMCE was re-created in 1916 and abolished in 1925. During the
Second Republic the Body of General Staff was finally suppressed and the EMCE was re-created. After the
Civil War, on August 31, 1939, the
High Command was created, the true predecessor of the current Defence Staff, with
Brigadier General Juan Vigón in front as chief of the General Staff. The High Command was active throughout
Francoist Spain and part of the
Spanish transition to democracy, disappearing on June 13, 1980. Three years earlier, in 1977, the
Joint Chiefs of Staff had been created as the principal body of the General Staff to advise the
prime minister and the
minister of defence and whose chairman was also the chief of the General Staff. This body assumed all the functions of the EMP when it was suppressed. In 1984, the Joint Chiefs of Staff was institutionalized and the position of Chief of the Defence Staff (JEMAD) was created, replacing the chairman of the Board of Chiefs of Staff. At the same time, the
Defence Staff was created to support the JEMAD. The Joint Chiefs of Staff was in force until 2005, when the new National Defence Organic Act created the National Defence Council as an advisory body to the prime minister and the minister of defence. ==List of chiefs of the Defence Staff==
