Historical archive of state ownership managed by the Ministry of Defense (Spanish Army), was declared National Archive in Royal Decree 2598/1998, of December 4 (Regulation of military archives).
In August 1969, part of the documentation repatriated from Equatorial Guinea after its independence in October 1968, sent by its Liquidating Commission, under the Presidency of the Government, and which basically contained records of reservists and the Colonial Guard of those territories, entered the Archive.
From 1970 onwards, it will begin to receive regularly from all the Recruitment Zones (since 1986 Recruitment Centers) the files of reservists or regulatory troop files, which previously sent the Recruitment Zones to the archive of Segovia. Since then, documentation has continued to be received annually from troop personnel who become fully licensed.
Between 1981 and 1982, some 5,000 legajos with personal files of generals, chiefs, officers, assimilates and civilian personnel and files of the Superior Preliminary Instruction (IPS) received in Guadalajara from military centers and units of the Spanish Army were sent to Segovia. The lack of space in the Military General Archive of Segovia encouraged the transfer, between 1981 and 1984, to Guadalajara of part of the former Section 7th of the archive, more than fifteen thousand files with files of Recruitment Zones and Recruiting Boxes, in addition to two thousand files with files of the group of funds of disciplinary battalions and the files of foreigners detained in the Concentration Camp of Miranda de Ebro.
In 1985, the Army ' s Legal Counsel sent the file of the Central Commission for the Review of Penalties, and in the same year the testimony of the Supreme Council of Military Justice was received.
From the nineties, we will also receive the personal files of the dissolved UCOS (Units, Centers and Agencies); files of mutilated deaths from the General Directorate of Mutilated, and from 2000 files of inmates (military prisons of Montjuich, Alcalá de Henares and Santa Catalina), files of the Mora Guard and files of Europeans of the Regiment of the Guard of the Head of State (Royal Guard), procedural files of the Concentration Camp La Alcazaba of Zeluan, as well as the Intermediate Battalion Soldiers.
Currently, the income from funds received in the General Military Archive of Guadalajara comes, for the most part, from the intermediate archives, although regulatory files to be interspersed are also received that produce the Recruitment Areas of the Delegations and Subdelegations of Defense.
