The '''International Brigades''' ({{langx|es|Brigadas Internacionales}}) were soldiers recruited and organized by the [[Communist International]] to assist the [[Popular Front (Spain)|Popular Front]] government of the [[Second Spanish Republic]] during the [[Spanish Civil War]]. The International Brigades existed for two years, from 1936 until 1938. It is estimated that during the entire war, there were between 40,000 and 59,000 Brigaders, including some 10,000 who died in combat. Beyond the [[Spanish Civil War]], "International Brigades" is also sometimes used interchangeably with the term [[List of foreign volunteers|foreign legion]] in reference to military units comprising foreigners who volunteer to fight in the military of another state, often in times of war.<ref>{{cite journal |url=https://direct.mit.edu/isec/article/46/1/147/102854/Leaning-on-Legionnaires-Why-Modern-States-Recruit |title=Leaning on Legionnaires: Why Modern States Recruit Foreign Soldiers |last=Grasmeder |first=Elizabeth M.F. |accessdate=30 July 2021 |newspaper=[[International Security]] |year=2021 |volume=46 |issue=1 |pages=147–195 |doi=10.1162/isec_a_00411 |s2cid=236094319 |doi-access= |archive-date=13 August 2021 |archive-url=https://web.archive.org/web/20210813105010/https://direct.mit.edu/isec/article/46/1/147/102854/Leaning-on-Legionnaires-Why-Modern-States-Recruit |url-status=live }}</ref>

The headquarters of the brigade was located at the Gran Hotel,<ref>{{Cite news|url=http://elpais.com/diario/2011/12/11/eps/1323588417_850215.html|title=Reportaje {{!}} La última brigadista|date=11 December 2011|work=EL PAÍS|access-date=27 April 2017|language=es|archive-date=11 April 2021|archive-url=https://web.archive.org/web/20210411024315/https://elpais.com/diario/2011/12/11/eps/1323588417_850215.html|url-status=live}}</ref> [[Albacete]], [[Castilla-La Mancha]]. They participated in the battles of [[Battle of Madrid|Madrid]], [[Battle of Jarama|Jarama]], [[Battle of Guadalajara|Guadalajara]], [[Battle of Brunete|Brunete]], [[Battle of Belchite (1937)|Belchite]], [[Battle of Teruel|Teruel]], [[Aragon Offensive|Aragon]] and [[Battle of the Ebro|the Ebro]]. Most of these ended in defeat. For the last year of its existence, the International Brigades were integrated into the [[Spanish Republican Army]] as part of the [[Spanish Foreign Legion]]. The organisation was dissolved on 23 September 1938 by Spanish Prime Minister [[Juan Negrín]] in a vain attempt to get more support from the liberal democracies on the [[Non-Intervention Committee]].

The International Brigades were strongly supported by the [[Comintern]] and represented the [[Soviet Union]]'s commitment to assisting the Spanish Republic (with arms, logistics, military advisers and the [[NKVD]]), just as [[Estado Novo (Portugal)|Portugal]], [[Fascist Italy (1922–1943)|Fascist Italy]], and [[Nazi Germany]] were assisting the opposing [[Nationalist faction (Spanish Civil War)|Nationalist insurgency]].<ref name="Thomas 2003">{{harvnb|Thomas|2003|pp= 941–945}}</ref> The largest number of volunteers came from France (where the [[French Communist Party]] had many members) and [[Communism|communist]] exiles from Italy and Germany. Many [[Jews]] were part of the brigades, being particularly numerous within the volunteers coming from the [[United States]], [[Poland]], [[France]], [[England]] and [[Argentina]].<ref>{{Cite journal|url=http://revistascientificas.filo.uba.ar/index.php/che/article/view/9046/7824|publisher=[[University of Buenos Aires|UBA]]|location=Buenos Aires|journal=Cuadernos de Historia de España|first=Raanan|last=Rein|author-link=Raanan Rein|issue=87|year=2020|title=De Moisés Ville a Madrid: Los argentinos judíos y la solidaridad con el bando republicano durante la Guerra Civil Española|pages=13–36|doi=10.34096/che.n87.9046|doi-access=free|access-date=10 December 2020|archive-date=24 June 2021|archive-url=https://web.archive.org/web/20210624195243/http://revistascientificas.filo.uba.ar/index.php/che/article/view/9046/7824|url-status=live}}</ref>

Republican volunteers who were opposed to [[Stalinism]] did not join the Brigades but instead enlisted in the separate [[Popular Front (Spain)|Popular Front]], the [[POUM]] (formed from [[Trotskyism|Trotskyist]], [[Right Opposition|Bukharinist]], and other [[Anti-Stalinist left|anti-Stalinist]] groups, which did not separate Spaniards and foreign volunteers),<ref name="Orwell 1984">{{harvnb|Orwell|1984}}</ref> or [[anarcho-syndicalist]] groups such as the [[Durruti Column]], the [[IWA–AIT|IWA]], and the [[Confederación Nacional del Trabajo|CNT]].

Using foreign [[Communist party|communist parties]] to recruit volunteers for Spain was first proposed in August 1936 by British writer and military theorist [[Tom Wintringham]] who had already travelled to Spain, but the idea was not formally raised with the Comintern in the Soviet Union until September 1936—apparently at the suggestion of [[Maurice Thorez]]<ref>{{harvnb|Beevor|1999|p=124}}</ref>—by [[Willi Münzenberg]], chief of [[Comintern]] propaganda for Western Europe. As a security measure, non-communist volunteers would first be interviewed by an [[First Chief Directorate|NKVD]] agent.

By the end of September, the British, Italian and French Communist Parties had decided to set up a column. [[Luigi Longo]], ex-leader of the Italian Communist Youth, was charged to make the necessary arrangements with the Spanish government. The [[Soviet Ministry of Defense]] also helped, since they had an experience of dealing with corps of international volunteers during the [[Russian Civil War]]. The idea was initially opposed by [[Largo Caballero]], but after the first setbacks of the war, he changed his mind and finally agreed to the operation on 22 October. However, the Soviet Union did not withdraw from the [[Non-Intervention Committee]], probably to avoid diplomatic conflict with France and the United Kingdom.

The main recruitment center was in Paris, under the supervision of Soviet colonel [[Karol Świerczewski|Karol "Walter" Świerczewski]]. On 17 October 1936, an open letter by [[Joseph Stalin]] to [[José Díaz (politician)|José Díaz]] was published in ''Mundo Obrero'', arguing that victory for the Spanish second republic was a matter not only for Spaniards but also for the whole of "progressive humanity"; in short order, communist activists joined with moderate socialist and liberal groups to form anti-fascist "popular front" militias in several countries, most of them under the control of or influenced by the [[Comintern]].<ref>{{Britannica|id=290606|title=Third International {{!}} association of political parties}}</ref>

Entry to Spain was arranged for volunteers, for instance, a Yugoslav, Josip Broz, who would become famous as [[Marshal of Yugoslavia|Marshal]] [[Josip Broz Tito|Tito]], was in Paris to provide assistance, money, and passports for volunteers from [[Eastern Europe]] (including numerous [[Yugoslav volunteers in the Spanish Civil War]]). Volunteers were sent by train or ship from France to Spain, and sent to the base at [[Albacete]]. Many of them also went by themselves to Spain. The volunteers were under no contract, nor defined engagement period, which would later prove a problem.

Also, many Italians, Germans, and people from other countries joined the movement, with the idea that combat in Spain was the first step to restore [[democracy]] or advance a revolutionary cause in their own country. There were also many unemployed workers (especially from France), and adventurers. Finally, some 500 communists who had been exiled to Russia were sent to Spain (among them, experienced military leaders from the First World War like [[Manfred Stern|"Kléber" Stern]], [[Wilhelm Zaisser|"Gomez" Zaisser]], [[Zalka Mate|"Lukacs" Zalka]] and [[Janos Galicz|"Gal" Galicz]], who would prove invaluable in combat).

The operation was met with enthusiasm by communists, but by [[anarchist]]s with skepticism, at best. At first, the anarchists, who controlled the borders with France, were told to refuse communist volunteers, but reluctantly allowed their passage after protests. Keith Scott Watson, a journalist who fought alongside Esmond Romilly at Cerro de los Ángeles and who later "resigned" from the [[Thälmann Battalion]], describes in his memoirs how he was detained and interrogated by Anarchist border guards before eventually being allowed into the country.<ref>{{cite book |title=Single to Spain |first=Keith Scott |last=Watson |orig-date=1937 |url=https://theclaptonpress.com/single-to-spain-escape-from-disaster-by-keith-scott-watson/ |year=2022|access-date=15 December 2022|archive-date=15 December 2022|archive-url=https://web.archive.org/web/20221215050331/https://theclaptonpress.com/single-to-spain-escape-from-disaster-by-keith-scott-watson/|url-status=live |isbn=978-1-913693-11-4 |publisher=The Clapton Press}}</ref> A group of 500 volunteers (mainly French, with a few exiled Poles and Germans) arrived in Albacete on 14 October 1936. They were met by international volunteers who had already been fighting in Spain: Germans from the [[Thälmann Battalion]], Italians from the [[Centuria Gastone Sozzi]] and French grouped together with Belgians under the Commune de Paris Battalion. Among them was the poet [[John Cornford]], who had travelled down through France and Spain with a group of fellow intellectuals and artists including Wintringham, [[John Sommerfield]], [[Bernard Knox]], [[Ralph Bates]] and Jan Kurzke, all of whom left detailed memoirs of their battle experiences.<ref>{{cite book|first=John |last=Sommerfield |title=Volunteer in Spain |location=London |publisher=Lawrence & Wishart Ltd. |year=1937}}</ref><ref>{{cite book |first=Tom |last=Wintringham |title=English Captain |location=London |publisher= Faber & Faber |year= 1939}}</ref><ref>{{cite book |first=Ralph |last=Bates |title=The Miraculous Horde |location=London |publisher=Johnathan Cape |year=1939}}</ref><ref>{{cite book |first=Jan |last=Kurzke |title=The Good Comrade: Memoirs of an International Brigader |url=https://theclaptonpress.com/jan-kurzke-the-good-comrade-memoirs-of-an-international-brigader/|publisher=The Clapton Press|year= 2021|access-date=15 December 2022|archive-date=15 December 2022|archive-url=https://web.archive.org/web/20221215050333/https://theclaptonpress.com/jan-kurzke-the-good-comrade-memoirs-of-an-international-brigader/|url-status=live |isbn=978-1-913693-06-0}}</ref>

On 30 May 1937, the Spanish liner ''[[MV Ciudad de Barcelona|Ciudad de Barcelona]]'', carrying 200–250 volunteers from [[Marseille]] to Spain, was torpedoed by a Nationalist submarine off the coast of [[Malgrat de Mar]]. The ship sank and up to 65 volunteers are estimated to have drowned.<ref>{{cite web|url=https://ciudaddebarcelona1937.wordpress.com/|title=The Sinking of the "Ciudad de Barcelona", 30th May 1937|work=Ciudad de Barcelona|access-date=20 March 2017|archive-date=3 July 2017|archive-url=https://web.archive.org/web/20170703232225/https://ciudaddebarcelona1937.wordpress.com/|url-status=live}}</ref>

Albacete soon became the International Brigades headquarters and its main depot. It was run by a ''troika'' of [[Comintern]] heavyweights: [[André Marty]] was commander; [[Luigi Longo]] (''Gallo'') was Inspector-General; and [[Giuseppe Di Vittorio]] (''Nicoletti'') was chief political commissar.<ref>{{harvnb|Thomas|2003|p=443}}</ref>

There were many Jewish volunteers amongst the brigadiers – about a quarter of the total. A Jewish company was formed within the Polish battalion that was named after [[Naftali Botwin]], a young Jewish communist killed in Poland in 1925.<ref>{{Cite book|last=Graham|first=Helen|url=https://www.worldcat.org/oclc/57243230|title=The Spanish Civil War: a very short introduction|date=2005|publisher=Oxford University Press|isbn=0-19-280377-8|location=Oxford|pages=44|oclc=57243230|access-date=7 May 2021|archive-date=25 May 2022|archive-url=https://web.archive.org/web/20220525113029/http://www.worldcat.org/oclc/57243230|url-status=live}}</ref>

The [[French Communist Party]] provided uniforms for the Brigades. They were organized into [[mixed brigade]]s, the basic military unit of the [[Spanish Republican Army|Republican People's Army]].<ref>{{cite book|title=Orden, circular, creando un Comisariado general de Guerra con la misión que se indica.|publisher=Gaceta de Madrid: diario oficial de la República|date=16 October 1936|volume=Año CCLXXV Tomo IV, Núm. 290|page=355|url=http://www.boe.es/datos/pdfs/BOE/1936/290/B00355-00355.pdf|access-date=30 July 2012|archive-date=19 November 2018|archive-url=https://web.archive.org/web/20181119132649/https://www.boe.es/datos/pdfs/BOE/1936/290/B00355-00355.pdf|url-status=live}}</ref> Discipline was severe. For several weeks, the Brigades were locked in their base while their strict military training was underway.

=== First engagements: Siege of Madrid ===
[[File:Flag of the International Brigades.svg|thumb|right|225px|The flag of the International Brigades was the [[Spanish Republican flag]] with the three-pointed star of the [[Popular Front (Spain)|Popular Front]] in the center]]
The [[Siege of Madrid|Battle of Madrid]] was a major success for the Republic, and staved off the prospect of a rapid defeat at the hands of [[Francisco Franco]]'s forces. The role of the International Brigades in this victory was generally recognized but was exaggerated by [[Comintern]] propaganda so that the outside world heard only of their victories and not those of Spanish units. So successful was such propaganda that the British Ambassador, Sir Henry Chilton, declared that there were no Spaniards in the army which had defended Madrid. The International Brigade forces that fought in Madrid arrived after another successful Republican fighting. Of the 40,000 Republican troops in the city, the foreign troops numbered less than 3,000.<ref>{{harvnb|Beevor|1999|pc=137}}; {{harvnb|Anderson|2003|p= 59}}.</ref>

Even though the International Brigades did not win the battle by themselves, nor significantly change the situation, they certainly did provide an example by their determined fighting and improved the morale of the population by demonstrating the concern of other nations in the fight. Many of the older members of the International Brigades provided valuable combat experience, having fought during the [[First World War]] (Spain remained neutral in 1914–1918) and the [[Irish War of Independence]] (some had fought in the [[British Army]] while others had fought in the [[Irish Republican Army]] (IRA)).

One of the strategic positions in Madrid was the [[Casa de Campo]]. There the Nationalist troops were [[Morocco|Moroccans]], commanded by General [[José Enrique Varela]]. They were stopped by III and IV Brigades of the [[Spanish Republican Army]].

On 9 November 1936, the [[XI International Brigade]] – comprising 1,900 men from the Edgar André Battalion, the Commune de Paris Battalion and the [[Dabrowski Battalion]], together with a British machine-gun company&nbsp;— took up position at the Casa de Campo. In the evening, its commander, [[Manfred Stern|General Kléber]], launched an assault on the Nationalist positions. This lasted for the whole night and part of the next morning. At the end of the fight, the Nationalist troops had been forced to retreat, abandoning all hopes of a direct assault on Madrid by Casa de Campo, while the XIth Brigade had lost a third of its personnel.<ref>{{cite book |title=Boadilla |first=Esmond |last=Romilly |publisher=[[The Clapton Press]] |location=London |year=2018 |isbn=978-1999654306}}</ref>

On 13 November, the 1,550-man strong [[XII International Brigade]], made up of the Thälmann Battalion, the [[Garibaldi Battalion]] and the André Marty Battalion, deployed. Commanded by [[Mate Zalka|General "Lukacs"]], they assaulted Nationalist positions on the high ground of Cerro de Los Angeles. As a result of language and communication problems, command issues, lack of rest, poor coordination with armored units, and insufficient artillery support, the attack failed.

On 19 November, the [[anarchist]] [[militia]]s were forced to retreat, and Nationalist troops&nbsp;— Moroccans and Spanish Foreign Legionnaires, covered by the Nazi [[Condor Legion]]&nbsp;— captured a foothold in the [[University City of Madrid|University City]]. The 11th Brigade was sent to drive the Nationalists out of the University City. The battle was extremely bloody, a mix of [[artillery]] and [[strategic bombing|aerial bombardment]], with [[bayonet]] and [[grenade]] fights, room by room. Anarchist leader [[Buenaventura Durruti]] was shot there on 19 November 1936 and died the next day. The battle in the university went on until three-quarters of the University City was under Nationalist control. Both sides then started setting up trenches and fortifications. It was then clear that any assault from either side would be far too costly; the Nationalist leaders had to renounce the idea of a direct assault on Madrid, and prepare for a [[siege]] of the capital.

On 13 December 1936, 18,000 nationalist troops attempted an attack to close the encirclement of Madrid at [[Guadarrama]]&nbsp;— an engagement known as the [[Second Battle of the Corunna Road|Battle of the Corunna Road]]. The Republicans sent in a Soviet armored unit, under General [[Dmitry Pavlov (general)|Dmitry Pavlov]], and both XI and XII International Brigades. Violent combat followed, and they stopped the Nationalist advance.

An attack was then launched by the Republic on the [[Córdoba, Spain|Córdoba]] front. The battle ended in a form of stalemate; a communique was issued, saying: "During the day the advance continued without the loss of any territory." Poets [[Ralph Winston Fox]] and [[John Cornford]] were killed at the [[Battle of Lopera]], as was Dubliner [[Tommy Wood (Irish communist)|Tommy Wood]], aged 17.<ref>{{Cite book |last=Stradling |first=R. A. |title=The Irish and the Spanish Civil War, 1936–39: Crusades in Conflict |date=1999 |publisher=Manchester University Press |isbn=978-1-901341-13-3 |page=151}}</ref> Eventually, the Nationalists advanced, taking the [[hydro electricity|hydroelectric]] station at El Campo. [[André Marty]] accused the commander of the [[Marseillaise Battalion]], Gaston Delasalle, of espionage and treason and had him executed. (It is doubtful that Delasalle would have been a spy for Francisco Franco; he was denounced by his second-in-command, André Heussler, who was subsequently executed for treason during World War II by the [[French Resistance]].)

Further Nationalist attempts after Christmas to encircle Madrid met with failure, but not without extremely violent combat. On 6 January 1937, the Thälmann Battalion arrived at [[Las Rozas de Madrid|Las Rozas]] and held its positions until it was destroyed as a fighting force. On 9 January, only 10&nbsp;km had been lost to the Nationalists, when the [[XIII International Brigade]] and [[XIV International Brigade]] and the 1st British Company, arrived in Madrid. Violent Republican assaults were launched in an attempt to retake the land, with little success. On 15 January, trenches and fortifications were built by both sides, resulting in a stalemate.

The Nationalists did not take Madrid until the very end of the war, in March 1939, when they marched in unopposed. There were some pockets of resistance during the subsequent months.

=== Battle of Jarama ===
On 6 February 1937, following the fall of [[Málaga]], the nationalists launched an attack on the [[Madrid]]–[[Andalusia]] road, south of Madrid. The Nationalists quickly advanced on the little town of [[Ciempozuelos]], held by the [[XV International Brigade]]. was composed of the [[British Battalion]] ([[Commonwealth of Nations|British Commonwealth]] and [[Irish people|Irish]]), the [[Dimitrov Battalion]] (miscellaneous [[Balkan]] nationalities), the [[Sixth February Battalion]] ([[Belgium|Belgians]] and French), the Canadian [[Mackenzie-Papineau Battalion]] and the [[Abraham Lincoln Brigade]]. An independent 80-men-strong (mainly) Irish unit, known afterward as the [[Connolly Column]], also fought. Battalions were rarely composed entirely of one nationality, rather they were, for the most part, a mix of many.

On 11 February 1937, a Nationalist brigade [[Battle of Jarama|launched a surprise attack]] on the André Marty Battalion ([[XIV International Brigade]]), killing its sentries silently and crossing the [[Jarama]]. The Garibaldi Battalion stopped the advance with heavy fire. At another point, the same tactic allowed the Nationalists to move their troops across the river. On 12 February, the British Battalion, [[XV International Brigade]] took the brunt of the attack, remaining under heavy fire for seven hours. The position became known as "Suicide Hill". At the end of the day, only 225 of the 600 members of the British battalion remained. One [[Company (military)|company]] was captured by ruse, when Nationalists advanced among their ranks singing ''[[The Internationale]]''.

On 17 February, the Republican Army counterattacked. On 23 and 27 February, the International Brigades were engaged, but with little success. The Lincoln Battalion was put under great pressure, with no artillery support. It suffered 120 killed and 175 wounded. Amongst the dead was the Irish poet [[Charles Donnelly (poet)|Charles Donnelly]] and Leo Greene.<ref>{{cite journal| title=The Enigma of Frank Ryan part 1| first=Michael| last=McInerney| journal=Old Limerick Journal| volume=1| date=December 1979| url=http://www.limerickcity.ie/media/Media,3920,en.pdf| access-date=25 June 2018| archive-date=29 September 2020| archive-url=https://web.archive.org/web/20200929191202/http://www.limerickcity.ie/media/Media,3920,en.pdf| url-status=dead}}</ref>

There were heavy casualties on both sides, and although "both claimed victory ... both suffered defeats".<ref>{{harvnb|Thomas|2003|p=579}}</ref> The battle resulted in a stalemate, with both sides digging in and creating elaborate trench systems. On 22 February 1937, the [[League of Nations]] [[Non-Intervention Committee]] ban on foreign volunteers went into effect.

=== Battle of Guadalajara ===
{{Main|Battle of Guadalajara}}
[[File:Garibaldi.svg|thumb|right|Flag of Garibaldi battalion of the XII International Brigade, formed by italian volunteers]]
After the failed assault on the Jarama, the Nationalists attempted another assault on Madrid, this time from the northeast. The objective was the town of [[Guadalajara, Spain|Guadalajara]], 50&nbsp;km from Madrid. The whole Italian expeditionary corps&nbsp;— 35,000 men, with 80 battle tanks and 200 field artillery&nbsp;— was deployed, as [[Benito Mussolini]] wanted the victory to be credited to Italy. On 9 March 1937, the Italians made a breach in the Republican lines but did not properly exploit the advance. However, the rest of the Nationalist army was advancing, and the situation appeared critical for the Republicans. A formation drawn from the best available units of the Republican army, including the [[XI International Brigade|XI]] and [[XII International Brigade]]s, was quickly assembled.

At dawn on 10 March, the Nationalists closed in, and by noon, the Garibaldi Battalion counterattacked. Some confusion arose from the fact that the sides were not aware of each other's movements, and that both sides spoke Italian; this resulted in scouts from both sides exchanging information without realizing they were enemies.<ref>{{harvnb|Beevor|1999|p=158}}</ref> The Republican lines advanced and made contact with XI International Brigade. Nationalist tanks were shot at and infantry patrols came into action.

On 11 March, the Nationalist army broke the front of the Republican army. The [[Thälmann Battalion]] suffered heavy losses but succeeded in holding the [[Trijueque]]–[[Torija]] road. The Garibaldi also held its positions. On 12 March, Republican planes and tanks attacked. The Thälmann Battalion attacked Trijuete in a bayonet charge and re-took the town, capturing numerous prisoners.

=== Other battles ===
The International Brigades also saw combat in the [[Battle of Teruel]] in January 1938. The [[35th International Division]] suffered heavily in this battle from aerial bombardment as well as shortages of food, winter clothing, and ammunition. The [[XIV International Brigade]] fought in the [[Battle of Ebro]] in July 1938, the last Republican offensive of the war.

=== Overview ===
{{for|military structure and organization|International Brigades order of battle}}
The first brigades were composed mostly of French, Belgian, Italian, and German volunteers, backed by a sizeable contingent of Polish miners from Northern France and Belgium. The [[XI International Brigade|XIth]], [[XII International Brigade|XIIth]] and [[XIII International Brigade|XIIIth]] were the first brigades formed. Later, the [[XIV International Brigade|XIVth]] and [[XV International Brigade|XVth]] Brigades were raised, mixing experienced soldiers with new volunteers. Smaller Brigades&nbsp;— the [[86th International Brigade|86th]], [[129th International Brigade|129th]] and [[150th International Brigade|150th]] – were formed in late 1937 and 1938, mostly for temporary tactical reasons.

About 32,000<ref name="Thomas 2003" /> foreigners volunteered to defend the Spanish Republic, the vast majority of them with the International Brigades. Many were veterans of World War I. Their early engagements in 1936 during the [[Siege of Madrid]] amply demonstrated their military and propaganda value.

The international volunteers were mainly socialists, communists, or others willing to accept communist authority, and a high proportion were [[Jewish volunteers in the Spanish Civil War|Jewish]]. Some were involved in the [[Barcelona]] [[May Days]] fighting against leftist opponents of the Communists: the Workers' Party of Marxist Unification ([[POUM]]) (''Partido Obrero de Unificación Marxista'', an anti-[[Stalinist]] Marxist party) and the [[anarchist]] [[CNT-FAI|CNT]] (CNT, Confederación Nacional del Trabajo) and [[Federación Anarquista Ibérica|FAI]] (FAI, Iberian Anarchist Federation), who had strong support in Catalonia. These libertarian groups attracted fewer foreign volunteers.

To simplify communication, the battalions usually concentrated on people of the same nationality or language group. The battalions were often (formally, at least) named after inspirational people or events. From spring 1937 onwards, many battalions contained one Spanish volunteer company of about 150 men.

Later in the war, military discipline tightened and learning Spanish became mandatory. By decree of 23 September 1937, the International Brigades formally became units of the [[Spanish Foreign Legion]].<ref name=" Beevor 2006/309">{{harvnb|Beevor|2006|p=309}}</ref> This made them subject to the Spanish Code of Military Justice. However, the Spanish Foreign Legion itself sided with the Nationalists throughout the coup and the civil war.<ref name=" Beevor 2006/309" /> The same decree also specified that non-Spanish officers in the Brigades should not exceed Spanish ones by more than 50 percent.<ref>{{harvnb|Castells |1974|pages= 258–259}}</ref>

[[File:Stamps of Germany (DDR) 1966, MiNr 1198.jpg|thumb|East German stamp honoring [[Hans Beimler (Communist)|Hans Beimler]] with a combat scene of the International Brigades in the background]]
After the Civil War was eventually won by the Nationalists, the brigaders were initially on the "wrong side" of history, especially as most of their home countries had right-wing governments (in France, for instance, the [[Popular Front (France)|Popular Front]] was not in power anymore). However, since most of these countries soon found themselves at war with the very powers which had been supporting the Nationalists, the brigadistas gained some prestige as the first guard of the democracies, as having foreseen the danger of fascism and gone to fight it. Some glory therefore accrued to the volunteers (a great many of the survivors also fought during World War II), but this soon faded in the fear that it would promote [[communism]] by association.

The highest-ranking post-war IB combatant was [[Koča Popović]], who briefly served as the vice-president of Yugoslavia (1966–1967). Two became prime ministers: [[Mehmet Shehu]] (Albania, 1954–1981) and [[Ferenc Münnich]] (Hungary, 1958–1961), while [[Heinrich Rau]] was the chairman of [[German Economic Commission|DWK]], sort of government of what would become East Germany (1948–1949). There were four deputy prime ministers: [[Petre Borilă]] (Romania, 1954–1965), [[:pl:Eugeniusz Szyr|Eugeniusz Szyr]] (Poland, 1959–1972), [[Gogu Rădulescu]] (Romania, 1963–1979), and [[Pietro Nenni]] (Italy, 1963–1968); [[Rodoljub Čolaković]] served as prime minister of Bosnia and Hercegovina, the federative component of Yugoslavia (1945-1948). In communist countries tens of ex-combatants served as ministers (e.g. [[Karlo Lukanov]] in Bulgaria, [[Josef Pavel]] in Czechoslovakia, [[Gheorghe Vasilichi]] in Romania, [[Ernő Gerő]] in Hungary, [[Maks Baće Milić|Maks Baće]] in Yugoslavia), or held other key state jobs, especially in the army and security (e.g. [[Erich Mielke]] in East Germany). In the West the only person holding a ministerial job identified was Nenni, though [[Lou Lichtveld]] was minister in the Dutch-dependent Surinam. In the West few became senators, like [[:it:Armando Fedeli|Armando Fedeli]] (Italy, 1948–1958) and [[Raymond Guyot|Raymond Guyeot]] (France, 1959–1977), and a handful served as members of lower houses in their national parliaments, especially in France (e.g. [[:fr:Auguste Lecœur|Auguste Lecœur]] in 1945-1955) and Italy (e.g. [[:it:Aristodemo Maniera|Aristodemo Maniera]] in 1948-1958); however, the highest-ranking combatant in national legislative was [[Ferdinand Kozovski]], the longtime chairman of the National Assembly of Bulgaria (1949–1966). Beyond the official state structures single individuals grew to high political positions: in the mid-1970s [[Jack Jones (trade unionist)|Jack Jones]] as General Secretary of General Workers Union was considered the most powerful person in Britain.

=== Canada ===
Survivors of the [[Mackenzie-Papineau Battalion]] were often investigated by the [[Royal Canadian Mounted Police]] and denied employment when they returned to Canada. Some were prevented from serving in the military during the Second World War due to "political unreliability".{{Citation needed|date=February 2021}}

Probably in no country of the world did the International Brigades combatants enjoy the prestige comparable to that bestowed on them in [[East Germany]].<ref>"only Poland came close in its adulation of former Spanish veterans", Arnold Krammer, ''The Cult of the Spanish Civil War in East Germany'', [in:] ''Journal of Contemporary History'' 39/4 (2004), p. 535. More detailed monographs are Josie McLellan, ''Anti-Fascism and Memory in East Germany.

No such narrative was available in the case of East Germany, whose “communist government found itself without historical roots beyond the Soviet occupation of Eastern Europe and turned the heroism of the Spanish Civil War fighters into the myth that became a central focus of the German Democratic Republic”.<ref> Arnold Krammer, ''[https://www.hsozkult.de/publicationreview/id/reb-6929 Internationale Brigaden in der DDR]'', [in:] ''H/Soz/Kult'' 42/2 (2005)</ref> Factional purges of the early 1950s affected German veterans (e.g. the cases of [[Franz Dahlem]] or [[Wilhelm Zaisser]]) far less than e.g. in Czechoslovakia, though some “Brigaders faced an uncertain existence as they navigated the tortuous political hairpin curves of life under Stalinism and the continual and often critical need for political realignment”.<ref>“by 1950, the Party had purified the anti-fascist movement of resistance workers, concentration camp survivors, and anti-Nazi spies, leaving only active fighters and committed Party members. What remained was to bring the story of the anti-fascist fighters, a common euphemism for the International Brigades, into ideological alignment”, Kramer 2005</ref>

Like in other communist countries, the IB veterans – usually referred to as ''Spanienkämpfer'' – were overrepresented in power structures. They took three of the most important military posts: [[Heinz Hoffmann]] as commander of [[National People's Army|Nationale Volksarmee]], [[Erich Mielke]] as head of Ministry for Security, and [[Friedrich Dickel]] as Minister of Interior. Many held other key posts in army and security, e.g. [[:de:Herbert Grünstein|Herbert Grünstein]] was Deputy Minister of the Interior while [[Ewald Munschke]] became chief of administration in NVA. There were 10 former interbrigadistas who entered the Political Bureau of [[Socialist Unity Party of Germany|Sozialistische Einheitspartei Deutschlands]], some briefly (e.g. [[Anton Ackermann]], Dahlem or Zaisser) and some for decades (e.g. [[Paul Verner]], [[Kurt Hager]] and [[Alfred Neumann (East German politician)|Alfred Neumann]]).<ref> Krammer 2004, p. 539</ref> Numerous ex-combatants assumed high positions in media.<ref> Max Kahane founded Allgemeiner Deutscher Nachrichtendienst and was the chief commentator of ''Neues Deutschland''. Georg Stibi was the chief editor of ''Berliner Zeitung'', then ''Leipziger Volkszeitung'', and finally ''Neues Deutschland''. Frieda Kantorowicz had a high administrative position with ADN. Erich Henschke was the editor-in-chief of ''Berliner Zeitung'' and Kurt Julius Goldstein held the same position in the Deutschlandsender broadcast station</ref> The list of veterans who “rose to the highest ranks in the East German government runs into hundreds”.<ref> Krammer 2004, p. 537</ref>

German participation in the International Brigades remained the ideological historiographic backbone of DDR until its collapse. East Germany itself officially acknowledged that “the German-speaking units of the International Brigades represented the nucleus of the armed forces of the future GDR”.<ref> Peter Joachim Lapp, ''Traditionspflege in der DDR'', Berlin [West] 1988, ISBN 9783921226322, pp. 74-75</ref> Books by [[Ludwig Renn]] became standard works and at times obligatory reading.<ref> Krammer 2004, p. 535</ref> Numerous streets, schools, bridges, factories and troop units were named after the ''Spanienkämpfer'';<ref> Krammer 2005</ref> in 1968 they were dedicated a monument, unveiled in East Berlin.<ref> ''[https://bildhauerei-in-berlin.de/bildwerk/denkmal-fuer-die-deutschen-interbrigadisten-5399/ Denkmal für die deutschen Interbrigadisten]'', [in:] ''Bildhauerei in Berlin'' sevice</ref> Attempts to challenge the propagandistic use of German IB history, like the 1979 novel ''Collin'' by [[Stefan Heym]], remained isolated episodes with no major impact. The 1986 fiftieth anniversary of the outbreak of the war saw another outpouring of adulation,<ref> Krammer 2004, p. 558</ref> even though over time the volunteers “became cardboard figures which mirrored the ossification of the State itself”.<ref> Krammer 2005</ref> However, only a few days before the [[fall of the Berlin Wall]], on November 5, 1989, [[Walter Janka]] appeared at a public reading of his memoirs to an overflow crowd at the [[Deutsches Theater (Berlin)|Deutsches Theater]]. The event was broadcast live on radio and shown later on television.<ref> Krammer 2004, p. 559</ref>

Most Czechoslovak volunteers<ref> it is estimated that out of Czechoslovak volunteers, only 66% were Czechs or Slovaks; 20% were Germans and 11% were Hungarians, Maroš Timko, ''Czechoslovak-Spanish relations (1918-1977)'' [MA thesis Univerzita Karlova v Praze], Praha 2022, p. 28</ref> remained in France; in 1939-40 many got enlisted in troops, raised by the exile government. Later their fate differed: some served in Czechoslovak units raised in Britain,<ref> Zdenko Maršálek, ''Internacionalisté pod drobnohledem. Interbrigadisté v československých jednotkách za druhé světové války pohledem sociologických kategorií'', [in:] ''Paginae historiae'' 25/1 (2017), p. 47</ref> some were members of [[French Resistance|French resistance]], some returned home, and some ended up in concentration camps.<ref> Jiří Nedvěd, ''Českoslovenští dobrovolníci, mezinárodní brigády a občanská válka ve Španělsku v letech 1936 – 1939'' [MA thesis Univerzita Karloyva v Praze], Praha 2008, pp. 147-149</ref>

In re-born [[Czechoslovakia]] the Interbrigadistas, known as ''španěláci'', were granted ex-combatant rights. They were overrepresented in [[Communist Party of Czechoslovakia|KSČ]]-controlled power structures (army, public order, security, intelligence). Some of them – like [[Josef Pavel|Pavel]] – were instrumental when carrying out the [[1948 Czechoslovak coup d'état|coup of February 1948]]. The ''Security Five'', key men controlling security institutions – was composed of former IB volunteers: Pavel, [[:cs:Leopold Hofman|Hofman]], [[Otakar Hromádko|Hromádko]], Valeš and [[:cs:Osvald Závodský|Závodský]].<ref> Timko 2022, pp. 73-74</ref> Some rose to deputy ministers ([[Artur London|London]] and [[:cs:Josef Dufek|Dufek]] in foreign affairs, [[:cs:Karol Hušek|Hušek]] in information and [[František Kriegel|Kriegel]] in health).<ref> Nedvěd 2008, pp. 149-152</ref>
[[File:Vlasta Vesela Feiglova (1911 1950).jpg|thumb|160px|[[:cs:Vlasta Veselá|Vlasta Veselá]], possibly tortured to death]]
At the turn of the decades a drastic wave of political purges heavily affected the former Interbrigadistas. Almost all lost their posts and many underwent brutal interrogation; [[:cs:Vlasta Veselá|Veselá]] died in prison. In the early 1950s there was a show-trial planned, intended to denounce “International Brigades as a Trotskyist-Titoist gang”,<ref> Timko 2022, p. 74</ref> though eventually most prison sentences were delivered during small-scale trials. In 1952 [[Otto Šling]] was executed as an enemy spy.<ref> Nedvěd 2008, pp. 152-154</ref>

Following another political change in 1956 those still behind bars were set free and gradually re-admitted to public administration. The 1960s was the golden era for Czechoslovak IB combatants, hailed as the first ones who confronted Fascism. Some (Holdoš, Kriegel, Falbra) took advantage of their linguistic skills and were despatched as advisors to [[Cuban Revolution|Castro’s Cuba]]. Politically the Czechoslovak Interbrigadistas tended to support the reformist wing of KSČ. Few rose to top positions, e.g. in 1968 Kriegel became chairman of the National Front, and Pavel assumed the ministry of interior.

The [[Warsaw Pact invasion of Czechoslovakia|invasion of 1968]] marked another downturn; most of these at high positions were dismissed, though there was no wave of heavy repression. Some resigned (Pavel, Holdoš), few left for exile (Hromádko) and some were involved in dissident movement (Kriegel). After 1989 there was some confusion in both Czechia and Slovakia as to how the IB veterans should be approached, though the controversy was not comparable to the similar one in Poland;<ref>when noting that “téma dokonce dodnes neztratilo na své kontroverznosti”, the Czech autor quotes the Polish example, not any from Czechia, Maršálek 2017, p. 44 </ref> eventually the image which seems to prevail is this of anti-fascist combatants. In 2016 the Czech minister of defense [[:cs:Karel Kühnl|Kühnl]] awarded commemorative medals to last living Interbrigadistas.<ref> Nedvěd 2008, pp. 154-156</ref> A 2021 monograph presents the ''španěláci'' in balanced, but somewhat sympathetic terms.<ref>compare David Majtenyi, Jiří Rajlich, ''Říkali jim Španěláci'', Praha 2021, ISBN 978-80-7573-099-2</ref>

In line with the 1920 legislation, Polish citizens who volunteered to the IB were automatically stripped of citizenship as individuals who without formal approval served in foreign armed forces.<ref>{{harvnb|Różycki| 2015|page= 149}}</ref> Following republican defeat the combatants recruited in France and Belgium returned there.<ref>{{harvnb|Różycki| 2015|page= 148}}</ref> Among the others some served in pro-Communist partisan units in the German-occupied Poland,<ref>individual paths from internment camps to occupied Poland differed, e.g. in 1940 some ex-combatants volunteered to German labor units, recruited in occupied France and deployed in the East; some fought in the Polish army in France or in the French army and were taken prisoner by the Germans, later released from Stalag camps</ref> while some made it to the USSR and served in the pro-Communist Polish army raised there.<ref>usually they remained in French internment camps in Algeria until liberated by the Americans; in 1942–1943 from Africa via Middle East they made it to the USSR. In few cases some Polish IB volunteers were recalled from Spain to the USSR in 1937-1939, mostly to be executed; this was the case e.g. of [[Kazimierz Cichowski]] and [[:pl:Gustaw Reicher|Gustaw Reicher]]</ref>

In the Communist Poland the IB combatants – referred to as ''Dąbrowszczacy''<ref>unlike e.g. in East Germany, Czechoslovakia or Yugoslavia, where IB volunteers gained collective names related to Spain (“Spanienkämpfer”, “španěláci”, “Španci”), in Poland it was not the case. The term “Hiszpanie” (Spaniards) briefly functioned in internal communist parlance, often to denote one of the party factions, but it was not used officially. The term “Dąbrowszczacy” [Dombrovskites] is derived from the surname of [[Jarosław Dąbrowski]], a 19th-century left-wing commander who had been adopted as patron of the XIII International Brigade, the unit where most volunteers from Poland used to serve</ref> - were granted veteran rights and formed an own ex-combatant organisation, later to be amalgamanted into a general one.<ref>{{harvnb|Różycki| 2015|pages=150-151}}</ref> In the early post-war period they enjoyed some official exaltation; the group was supported by Karol Świerczewski, in Spain a career Soviet commander who during few strings commanded IB units.<ref>{{harvnb|Różycki| 2015|page=152}}</ref> Some assumed high positions in administration,<ref>the highest-ranking IB combatant was Eugeniusz Szyr, who served as deputy prime minister in 1959–1972, {{harvnb|Pietrzak|2016|page=78}}</ref> but they were heavily overrepresented in power structures (army, security);<ref>key figures were Mieczysław Mietkowski, Grzegorz Korczyński, Leon Rubinstein, Józef Mrozek, Franciszek Księżarczyk, Mieczysław Broniatowski, Henryk Toruńczyk, Juliusz Hibner, Jan Rutkowski, Paweł Szkliniarz, and Wacław Komar, who held various jobs in the Ministry of Defence, Ministry of Interior, army (especially counter-intelligence), and police, Pietrzak 2016, p. 78</ref> some departments became their fiefdoms, like counter-intelligence branch of the army.<ref>{{harvnb|Różycki| 2015|page=180}}</ref> During purges of early 1950s there were also cases of deposition, arrest and prison on trumped-up charges of political conspiracy;<ref>Grzegorz Korczyński, Wacław Komar, Stanisław Flato, Michał Bron, Wiktor Taubenfliegel, Pietrzak 2016, p. 78</ref> these were released in the mid-1950s.<ref>{{harvnb|Różycki| 2015|page=186}}</ref>

Though from the onset Polish engagement in IB was hailed as "working class taking to arms against Fascism", the most intense idolization took place between the mid-1950s and the mid-1960s, with a spate of publications, schools and streets named after ''Dąbrowszczacy''.<ref>{{harvnb|Różycki| 2015|pages=186-187}}</ref> However, an antisemitic turn in the late 1960s again produced de-emphasizing of IB volunteers, many of whom left Poland.<ref>{{harvnb|Różycki| 2015|pages=187-188}}. The best-known are Emanuel Mink, Michał Bron, Wiktor Taubenfligel, Józef Kutin, Eugenia Łozińska, Aleksander Szurek, Artur Kowalski and Ludwik Zagórski</ref> Until the end of Communist rule the IB episode was duly acknowledged, but propaganda related was a far cry from veneration reserved for wartime Communist partisans or the USSR-raised Polish army.<ref>{{harvnb|Różycki| 2015|pages=188-190}}</ref> Despite some efforts on part of IB combatants, no monument has been erected.<ref>except a commemorative stone in the Powązki military cemetery</ref> Unlike in East Germany, except [[:pl:Eugeniusz Szyr|Szyr]] no-one made it to the very top strata of the Communist elite (member of [[Politburo of the Polish United Workers' Party|Political Bureau of PZPR]], minister).

After 1989 it was unclear whether ''Dąbrowszczacy'' were furtherly entitled to veteran privileges; the issue generated political debates until they became pointless, as almost all IB combatants had passed away.<ref>the legislation adopted in 1991 declared that veterans are individuals who "actively participated in the struggles for Poland's independence and sovereignty"; the veteran status allowed a number of privileges, see {{cite web | last=Dubisz | first=Radosław | title=Veteran Privileges | website=Urząd do Spraw Kombatantów i Osób Represjonowanych | date=2023-10-09 | url=https://test.kombatanci.gov.pl/en/privileges/privilege-list/299-veteran-s-privileges.html | archive-url=https://web.archive.org/web/20221203055235/https://test.kombatanci.gov.pl/en/privileges/privilege-list/299-veteran-s-privileges.html | archive-date=2022-12-03 | url-status=live}}</ref> Another question was about homage references, existent in public space.

In 1996, [[Jacques Chirac]], then [[French President]], granted the former French members of the International Brigades the legal status of former service personnel ("ancient combatants") following the request of two French communist [[Members of Parliament]], Lefort and Asensi, both children of volunteers. Before 1996, the same request was turned down several times including by [[François Mitterrand]], the former Socialist President.

== Symbolism and heraldry ==
The International Brigades were inheritors of a socialist aesthetic. The flags featured the [[Flag of the Second Spanish Republic|colors of the Spanish Republic]]: red, yellow and purple, often along with socialist symbols ([[red flag (politics)|red flags]], [[hammer and sickle]], [[Raised fist#Salute|fist]]). The emblem of the brigades themselves was the three-pointed red star, which is often featured.<ref>{{cite web|url=https://www.flaginstitute.org/pdfs/Sebastia%20Herreros.pdf|last=Herreros i Agüí|first=Sebastià|title=The International Brigades in the Spanish War [''sic''] 1936&ndash;1939: Flags and Symbols|work=Proceedings of the XIX Congress of [[Vexillology]]|pages=141–165|publisher=[[Flag Institute]]|location=London|date=2001|access-date=18 June 2024}}</ref>
