It was created to increase the spatial possibilities of the Archival Subsystem of the Spanish Army, whose two main Historical Archives - the Central Archive of the Military Historical Service, now the General Military Archive of Madrid, and the General Military Archive of Segovia - were saturated.
In the former headquarters of the Academy of Intendence of Ávila, located next to the Palace of Polentinos - declared a National Monument - the Spanish Army has a set of facilities that, together with the great cultural value they treasure, allow them to face the growth of their Archives with a clear future perspective.
The initial nucleus of the funds of the General Military Archive of Ávila is the former Historical Archive of the Campaign, which in 1939 unified in a single archive the military documentation of the Francoist Army and the Republican Army. To this initial fund would be later incorporated the National Militia Archive, composed of two funds: on the one hand that of the National Militia units themselves (Falange and Requetés) and, on the other, the fund of the Spanish Division of Volunteers (Blue Division). Both blocks were transferred from the Central Archive of the Military Historical Service, now the General Military Archive of Madrid, in 1994.
In this main nucleus of the Archive, the funds of the institutions and organs of the Central Administration, both before the War, as is the case of the Ministry of the Army, and of the republican and Francoist zone (Ministry of War, Ministry of National Defense, Ministry of Interior, Ministry of Finance, Ministry of State, National Defense Board, Headquarters of the Generalissimo, etc. ).
Likewise, funds are kept from institutions and bodies of the Territorial Administration, such as those of the Government of the Basque Country, the Generalitat de Catalunya, Military Commanders and Governments.
As for the units of the People’s Army, it gathers the documentation of Armies, Armies, Divisions, Mixed Brigades, International Brigades, Columns and Air Forces, among others. The units of the so-called National Army, gather the documentation of the different Armies, Army Corps, Divisions, etc.
To these funds were later incorporated others, such as those of Blood Hospitals, General Captaincies, Military House of Franco, Construction Commanders, Toledo Weapons Factory, documentation of the units located in the territories of Ifni and Sahara, Academies and Teaching Centers, among the most relevant.
The archives complete the various documentary collections of photographs, objects or press clippings, many of them collected and sent by the Military Historical Service and some private archives donated by their owners.
Most of the documentation arrived at the archive organized in some cases by the Military Archives Regulation of 1898, in others by the instruction of 1939 and more recently by the principle of origin, given the circumstance that funds transferred at different times may have arrived classified by different regulations.
