that tore Europe apart, requiring the recruitment of soldiers from across Europe. With such numbers involved, Spain had trouble funding the war effort on so many fronts. The non-payment of troops led to many mutinies and events such as the
Sack of Antwerp (1576), in which 17,000 people died.
The Thirty Years' War (1618–1648) drew in Spain alongside most other European states. Spain entered the conflict with a strong position, but the ongoing fighting gradually eroded her advantages; first Dutch, then Swedish innovations had made the
tercio more vulnerable, having less flexibility and
firepower than its more modern equivalents. Nevertheless, Spanish armies continued to win major battles and sieges throughout this period across large swathes of Europe. French entry into the war in 1635 put additional pressure on Spain, with the French victory at the
Battle of Rocroi in 1643 being a major boost for the French. By the signing of the

the guerrilla insurgents increasingly took control of Spain's battle against Napoleon and created a more or less unified underground
national resistance, for which
traditional armies of the time were not organized or prepared for yet. By 1812, however, the army controlled only scattered enclaves, and could only harass the French with occasional raids. Fortunately for the Spanish, the disastrous
French invasion of Russia severely weakened the French Army and forced Napoleon to cut troop concentrations in Spain, ultimately allowing the Army, militia and their British allies to drive the French out of Spain by 1814.

, which had broken out in 1808, led to the loss of a majority of these colonial possessions by 1833. During these conflicts, numerous armies from Spain were dispatched to Spanish America in order to defeat the
Latin American revolutionaries; these efforts proved mostly unsuccessful. Combined with disturbances in Spain against the
Spanish government, Spain's military strength suffered further during the post-Napoleonic era of the early 19th century. Recognizing the need to reform the Spanish Army, reforms were passed by the government of Spain during this period to reform and modernize the armed forces into a professional

was adopted by the Spanish Army. This grew the size of the Army to 250,000 in 1828, and it increased in 1830 to 300,000 soldiers. This therefore made the Spanish Army a relatively strong Army in Europe, though internal conflicts did affect the Army, forcing them to choose sides.
Spain faced a series of internal dynastic conflicts, collectively known as the
Carlist Wars (1833–1876), during the 19th century; these conflicts led the Spanish state to undergo a series of reforms directed at its military, administrative, and social structures. As consequence of the Carlist Wars, and the weakness of the central structures of government under the
Spanish monarchy, many generals with political ambitions staged ''

At the end of the Civil War, the
Francoist (Nationalist) Army counted 1,020,500 men, in 60 divisions.

Madrid: IUGM-UNED. 2010. pp. 15–55.] During the first year of peace, Franco dramatically reduced the size of the Spanish Army to 250,000 in early 1940, with most soldiers two-year conscripts.
[
]
In October 1940, the Army had sixteen line infantry divisions; three mountain divisions; one cavalry division; and five divisions in
Spanish Morocco (IX Army Corps and X Army Corps), for a total of twenty-five. Other units included, in addition to those of the army corps in each captaincy: four tank regiments; field artillery, coastal and anti-aircraft regiments; regiments of different engineering specialties; the garrisons of the Canary Islands, the Balearic Islands, Ceuta and Melilla, Ifni-Sahara, and the naval bases; and more than one hundred workers' battalions.
A few weeks after the end of the war, the
eight traditional Military Regions (Madrid, Sevilla, Valencia, Barcelona, Zaragoza, Burgos, Valladolid, and the
VIII Military Region at La Coruña) were reestablished. In 1944 the
IX Military Region, with its headquarters in Granada, was created.

International isolation
At the end of the Second World War, the Spanish Army counted 22,000 officers, 3,000 NCO and almost 300,000 soldiers. The equipment dated from the Civil War, with some systems produced in Germany during the World War. Their doctrines and training were obsolete, as they had not incorporated the teachings of the Second World War; Scianna elaborates on the weaknesses of equipment, political role, and worldview. This situation lasted until the agreements with the United States in September 1953.
Agreement with the United States (Barroso Reform, 1957)
After the signing of the
military agreement with the United States in 1953, the assistance received from Washington allowed Spain to procure more modern equipment and to improve the country's defence capabilities. More than 200 Spanish officers and NCOs received specialised training in the United States each year. With the Barroso Reform (1957), the Spanish Army abandoned the organisation inherited from the Civil War to adopt the United States'
pentomic structure.
General Instruction 158/107 of 1958 led to the raising of three experimental infantry divisions (DIE 11 at Madrid, DIE "Guzman el Bueno" 21 at Algeciras, and DIE 31 at Valencia). Instruction 160/115 of January 15, 1960 extended these changes to another five transformation divisions (DIT, at Gerona, Málaga, Oviedo, Vigo, Vitoria, respectively) and the four mountain divisions (divisións de infantería de montaña, DIM). Most of the heavy divisions had five manoeuvre based on two to three regiments and support formations, while the Mountain Divisions "Urgel" 42, 51, 52, and "Navarra" 62 had six anchored on two to three regiments, an independent company, and what appears to be a battalion of motorised infantry.
Theoretically, these divisions were divided between three corps that would have reached across the boundaries of the Captaincies General if they had been formed:
* Army Corps 1 (Madrid): DIE 11, DIE 61, DIT 71, DIT 81;
* Army Corps 2 (Seville): DIE 21, DIE 31, DIT 41, DIT 91;
* Army Corps 3 (Zaragoza): DIM 42, DIM 51, DIM 52, DIM 62.
All in all, after the Barroso Reform, the Spanish Army had eight Pentomic infantry divisions, four mountain divisions,
Armoured Division No. 1 "Brunete", the "Jarama" Cavalry Division, organized into a division HQ and four armoured groups ("agrupaciones blindadas"), three independent Armoured Brigades at rather reduced strength, and three Field Artillery Brigades ("Brigada de artillería de campaña") with assigned artillery groups.
Years of economic development (1965)
The 1965 Reforms were inspired by then-contemporary French organisation and doctrine.
Camilo Menéndez Tolosa's reforms from 1965 divided the Army into two categories: the Immediate Intervention Forces (FII, Field Army) and the Defensa Operativa del Territorio (DOT, Operational Territorial Defence (Territorial Army)) territorial forces.

The FII had the mission of defending the Pyrenean and the Gibraltar frontiers and of fulfilling Spain's security commitments abroad. It was to be "an army corps equipped and trained for conventional and limited nuclear warfare, ready to be deployed within or outside national borders." It was made up of:
*
Armoured Division No. 1 "Brunete", with two armoured Brigades;
*
Mechanised Infantry Division "Guzmán el Bueno" No. 2, with Mechanised Infantry Brigade XXI (BRIMZ XXI) at
Cordoba, and Motorised Infantry Brigade XXII (BRIMT XXII) at
Jerez;
*
Motorised Division "Maestrazgo" No. 3 with its headquarters in

and two brigades;
*
Parachute Brigade (raised 1973)
* Air-Transportable Brigade
* Armoured Cavalry Brigade
* Army Corps support units
The DOT was to maintain security in the regional commands and of reinforce the
Civil Guard and the police against subversion and terrorism. It comprised nine independent Infantry Brigades (one in every one of the
Military Regions of Spain), organized with a brigade HQ and two infantry battalions each; the
Mountain Infantry Division No. 4 "Urgell" and
Mountain Infantry Division No. 6 "Navarra"; the Mountain Reserve of the Army High Command; the Canary Islands, Balearic Islands, Ceuta and Melilla commands, with their respective DOT units including the
Regulares (six groups later reduced to four) and the Spanish Legion (4 Tercios); and the Army General Reserve Command, composed of DOT units working as the reserve force of the Army, the equivalent to the United States Army Reserve.
During the last years of the Francoist regime, contemporary weapons and vehicles were ordered for the Army. In 1973, the military education system was reformed in depth, in order to make its structure and objectives similar to those existing in the civilian universities. It was during this time that the Spanish Army fought in the campaigns in what is now

The Cold War was a period of global Geopolitics, geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which lasted from 1947 unt ...
meant the disappearance of the Eastern Bloc threat. The reduction of the term of military service for conscripts until its complete abolition in 2001 and the increasing participation of Spanish forces in multinational peacekeeping operations abroad were the main drivers for changes in the army after 1989.
Three reorganisation plans have been implemented since. The first was the RETO plan (1990).
In 1994, Plan NORTE was published, which was implemented between 1995 and 1999. NORTE eliminated four of the five existing divisions, leaving the Army composed of the Permanent Force and the Mobilizable Reserve.
The Permanent Force included a mechanized division of three brigades, a cavalry brigade, a parachute brigade, a light airborne brigade, a Legion brigade, a mountain hunter brigade, the garrison forces of the Canary Islands, the Balearic Islands, Ceuta and Melilla, and other support elements. The now "Manoeuvre Force", located in the old Captaincy of Valencia, was reduced to an army corps equivalent of a complete heavy division and the equivalent of a light division with reduced support. The Mobilizable Reserve included three mobilizable infantry brigades, a mobilizable cavalry brigade and other support units. The captaincies general finally disappeared, being replaced by regional commands. The third plan was the Instruction for Organisation and Operation of the Army (IOFET) 2005.

* Antiquated material and limited budgets were not the only reasons for the army's low potential wartime capability after World War II. "..Spain continued to field around twenty divisions, whereas the defence industry and available national resources could only sustain six operational divisions. A regular Spanish infantry division could muster full strength with modern infantry weapons, while other ‘teeth’ units – like the artillery and engineers – were reduced to one-third of their ideal levels. The supporting ‘tail’ was so underdeveloped that divisions were statically bound to their home depot and could only defend their military district after six months mobilisation.."
