The Spanish Republican Army ( es, Ejército de la República Española) was the main branch of the
Armed Forces of the
Second Spanish Republic between 1931 and 1939.
It became known as People's Army of the Republic (''Ejército Popular de la República'') after it was reorganized, following the disbandment of the voluntary militias that were formed in July 1936 at the beginning of the

History
The Spanish Republican Army went through two clear phases during its existence:
* The pre-Civil War phase, before the
coup of July 1936 that would fracture the Spanish military institution
*The Civil War reorganization of the forces that remained loyal to the established republican government.

in Spain by making speech against "Spain and its symbols"—the Spanish Armed Forces including themselves as one of the symbols— a criminal offence. According to renowned writer
Salvador de Madariaga the Spanish Armed Forces became henceforward a "State within the State" that would interfere in civilian matters in an overbearing manner, becoming a major player in Spanish politics. Other Spanish intellectuals such as
Miguel de Unamuno and
Ramiro de Maeztu were seriously worried at the time about the future implications of the "Law of Jurisdictions". Unamuno openly expressed his concern that it would be left to the military to define what was correct regarding patriotism.
The "Moroccan Question" ( es, la cuestión marroquí), however, would be the main cause of the ensuing fractures in the political and social life in Spain. The disastrous
wars in Morocco ended up bringing about severe social reactions in Spain that could no longer be silenced by means of the "Law of Jurisdictions". The
Tragic Week protests in Barcelona in July 1909, which quickly turned
anticlerical, were primarily the result of the unpopular Moroccan wars that "merely satisfied the needs of the Military" in the eyes of the public.
The consequence of such developments was that the division between the Spanish military and the Spanish people became deeper. The liberal traditions that the Spanish Army had spearheaded in the 19th century were replaced by a defensive, reactionary outlook. The mutual suspicion led to the creation of the ''Juntas de Defensa'' (Boards of Defence) during the
1917 Spanish crisis caused by the
First World War

. The Spanish military had an excess of officers, as much as 16,000 officers for 80,000 troops at one point and the economic crisis, coupled with a low pay, brought the problem of the economic hardships of military families to the fore. Allegedly the aim of the ''Juntas de Defensa'' was to defend the interests of Spanish military officers, but their intention to get involved in political issues was clear to the public. Finally on 13 September 1923,
General Miguel Primo de Rivera made a successful
coup d'etat. After overthrowing the parliamentary government he established himself as dictator with the tacit consent of King
Alfonso XIII.
The General's dictatorship, however, did not solve the problems of the Spanish Armed Forces for the support of the military institution for General Primo de Rivera's move was not unanimous. Already in 1926 there was the first serious attempt of a coup, popularly known as ''La Sanjuanada'' (after St John), against the dictator in which four high-ranking generals —

Domingo Batet,

The first years of the Republic (1931–1936)

In 1931, following the proclamation of the Second Spanish Republic, the armed forces of the Spanish Kingdom became the Spanish Republican Armed Forces.
Admiral Aznar's casual comment: "Do you think it was a little thing what happened yesterday, that Spain went to bed as a monarchy and rose as a republic" became instantly famous, going quickly around Madrid and around Spain, making people accept the fact and setting a more relaxed mood. Republicans within the Spanish Armed forces were then a minority, but so were pro-monarchist reactionaries; the majority within the military were at first indifferent.
What began to antagonize the Spanish Military against the new government were the reforms of the armed forces introduced by newly nominated Republican

Later in October the same year Azaña became Prime Minister and continued the reform of the bloated and old-fashioned military the Republic had inherited. This was seen as a necessary step with the goal to modernize the Spanish Military and cut down the expenses of the state in the aftermath of the
Great Depression. In order to implement its reforms the Republican Government promoted to high posts military men that it perceived as loyal. As a result, it tended to display favoritism towards the branches of the Armed Forces more amenable to its reforms, the

generals in July 1936, militias were formed in many cities in Spain that had not sided with the rebellion lest the units of the Spanish Republican Army stationed in their territory be tempted to join the rebels.
Finally in October the Republican government reorganized its armed forces around the military units that had remained loyal and the militias were merged with the new army.
October 1936: First wartime reorganization

The government of the areas that had not joined the rebels, known as 'Victory Government' (''Gobierno de la Victoria''), quickly organized a 'Regular Popular Army' (''Ejército Popular Regular'') (EPR). Led by all the parties composing the
Popular Front (''Frente Popular''), and by the

The new structure sought to impose a more effective coordination of the loyalist forces, for the Republican government had lost effective control of the armed units defending it.

, as well as all scattered militias, a process that was gradually implemented with the goal of completion by February 1937. By 30 October all Spanish males aged between 20 and 45 were being conscripted.
The restructuring of the Spanish Republican Army showed the
Communist influence in the new discipline imposed by the Popular Front authorities. The new Republican People's Army instituted the ''Comisariado de Guerra'' by means of which
political commissars were charged with the mission of lifting the morale of the troops and ensuring their cooperation with their high-rank officers in all units. The commissar had to overcome the mistrust of the troops towards the officers in order to achieve the necessary discipline for proper coordination.
Based on a model that would replace the columns (''columnas'') and militias, the Mixed Brigade (''Brigada mixta'') was the basic military unit of the Republican People's Army. The first six
Mixed Brigades were created on 18 October 1936. The first was led by Communist colonel

Development of the war
The Spanish Republican Army units often lacked proper equipment. The situation improved somewhat by spring 1937, but a large proportion of units remained short of equipment and ammunition throughout the war.
The shortage of proper clothing, boots, weapons and ammunition was especially acute during the first months of the war, right after the reorganization. Priority, however, was given to ensure that the Republican troops received adequate food rations and that they received their salaries. Usually the latter were paid to the soldier's families in their homes.
The reorganization of the Spanish Republican Army was almost complete by mid-1937. Groups such as the Antifascist Worker and Peasant Militias, ''
Milicias Antifascistas Obreras y Campesinas'' (MAOC), the militias of the Socialist Youth (''
Juventudes Socialistas Unificadas''), the Communist Fifth Regiment, as well as the Anarchist militias were rallied under one banner and given proper military training. In places such as the

Front, however, the Anarchist and minority Communist groups, such as the

Mussolini, the first Soviet war supplies arrived to alleviate the lack of material in the loyalist side.
The People's Republican Army reached its highest level of organization in the
Battle of the Ebro, during the last half of 1938, but it was also the battlefield where it was broken. Very young soldiers, averaging 17 and a half in age, whose unit was known as the 'Baby bottle conscription' (''"quinta del biberón"'') would be mobilized for this last big battle of the Civil War, the last one in which the International Brigades operated. These type of large war operations fulfilled the
Communist propaganda goals promoted by Juan Negrín and his clique, but were disastrous and wasteful for the Spanish Republican Army, whose energy and organization would have been better employed in small-scale operations.

Central Region Army Group
The
Central Region Army Group, ''Grupo de Ejércitos de la Región Central'' (GERC), was an army group that gathered all the republican units that fought in the Republican Central Zone (''zona centro''). The GERC was led by
Defence of Madrid hero, General
José Miaja Menant. It was the most powerful section of the republican military that would endure until the 1939 surrender.
Eastern Region Army Group
The
Eastern Region Army Group ''Grupo de Ejércitos de la Región Oriental (GERO)'', included the armies that were defending Catalonia that were still loyal to the Spanish Republic led by General
Juan Hernández Saravia. It was more short-lived than the GERC, for this army group would be annihilated by the rebel forces during the
Catalonia Campaign

[Ejército del Aire – 1913]
During the years that followed, most of the warfare activity of the ''Aeronáutica Militar'' took place in Spanish Morocco.
Shortly thereafter the ''
Aeronáutica Naval'', the air branch of the
Spanish Navy, already established through a Royal decree four years earlier, became functional in
El Prat, in the same location as present-day
Barcelona Airport.

Under Capitan Warlela
cadastral surveys of Spain were carried out using modern methods of
aerial photography in 1933 and the following year Commander
Eduardo Sáenz de Buruaga became new chief-commander of the ''Aeronáutica Militar''.
Following a Government decree dated 2 October 1935, the Dirección General de Aeronáutica was placed under the authority of the War Ministry, ''Ministerio de la Guerra'', instead of under the ''
Presidencia del Gobierno'', following which in 1936 the regional units became restructured. Accordingly, the Spanish Navy-based ''Escuadra'' model was replaced by ''Región Militar'' divisions which are still operative today.
The ''Aeronáutica Militar'' was merged with the air arm of the Spanish Republican Navy in September 1936, after the reorganization of the armed forces following the July 1936 coup, becoming part of the Spanish Republican Air Force.
Ranks

In the Civil War, and following the reorganization of the Spanish Republican Armed Forces, the five pointed red star became an insignia of Spanish Republican Army uniforms.
The new insignia mainly replaced the former eight-pointed and six-pointed silver stars that had been part of the Republican Army officers' uniforms between 1931 and 1936.
