Yugoslavia between the World Wars

Formed in 1918 as the Kingdom of Serbs, Croats and Slovenes, then renamed Yugoslavia in 1929, the Kingdom of Yugoslavia lasted until 1941. Initially uniting the territories of the former Austro-Hungarian and Ottoman Empires into the Kingdom of Serbia, it faced problems such as ethnic tensions, political instability and, eventually, invasion and occupation by the Axis powers during World War II.
Introduction
No other European country was as colorful, multifaceted and complex as Yugoslavia, and its turbulent story made it the personification of chaos, confusion and hostility in the Balkans. The end of World War I radically changed the political map of Europe. Four empires disappeared overnight: the Russian, Ottoman, Austro-Hungarian and German, and on their ruins a number of independent national states arose, among which a new state entity appeared - the Kingdom of Serbs, Croats and Slovenes (KSCS), which included the peoples of the Balkan Peninsula, based on the idea of unifying the southern Slavs.

King Peter I of Serbia. 1918. In the cauldron of Balkan politics, King Peter I of Serbia (1844–1921) was considered a national hero for ending the rivalry between two warring dynasties, the Karadjordjevics and Obrenovic. King Peter was fifty-eight years old when he returned to Belgrade in triumph and was crowned in 1904, beginning a reign that many remember as Serbia’s Golden Age. The king supported a benevolent constitutional monarchy governed by a democratic parliament and was an ardent supporter of Yugoslav unification.
But these peoples, who suddenly found themselves together in a new state formation, lived in different empires and civilizations, they professed different religions and were strangers to each other...
Retrospective
Even when the First World War was raging in 1914, a South Slavic committee was created in Rome by Balkan emigrants, which decided the key question – which states and within what borders would be created in the Balkans, in the event of the victory of the Entente and the collapse of Austria-Hungary. On December 7, 1914, the Serbian National Assembly adopted the Niš Declaration, in which it defined the final goals of the war – "to fight for the liberation of the still unliberated Yugoslav territories of Austria-Hungary".

Note. Declaration – a document adopted on December 7, 1914 by the National Assembly of Serbia in the temporary capital of Niš (southern Serbia), which declared the struggle for the liberation and unification of the "unfree brothers" and the unification of all southern Slavs living in the Habsburg Empire into a single state. It should be noted here that the Entente, although an ally of Serbia in this war, still supported the preservation of Austria-Hungary and did not accept the ideas of the National Assembly for the post-war structure in the Balkans, as set out in the Niš Declaration.

The Orient Hotel in Niš, where the Niš Declaration was adopted. The Niš Declaration was a document adopted by the Kingdom of Serbia on 7 December 1914 during World War I, outlining Serbia's wartime goals, including the unification of all South Slavs into a single state "on the ruins of Austria-Hungary". The declaration was a strategic move to gain support from the South Slavs of Austria-Hungary and to present Serbia's war aims as liberation rather than mere self-defense.
In 1915, this committee moved to London, where its influence on the Allied politicians was much greater than its size. Although this committee, financed by the Serbian government, consisted mainly of Slovenes and Croats, it was still against Greater Serbia and advocated an equal union of nations, although it recognized that since Serbia was already an established state and had an apparatus of state administration, the new South Slavic state should unite around it. In addition, after the two Balkan Wars (1912-1913), Serbia had significantly increased its territory and population, which, combined with greater sympathy for it on the part of the South Slavic peoples, further increased its self-confidence.

Belgrade during the Austro-Hungarian occupation of 1915-1918. In December 1914, the Austro-Hungarian troops captured Belgrade, but its occupation was short-lived, as the Serbian army repelled the aggressors after the Battle of Kolubara in late 1914, but the second occupation lasted from autumn 1915 until the end of World War I. During the Austro-Hungarian occupation of Belgrade from 1915 to 1918, the city was administered by the Serbian Military General Government, established by the Austro-Hungarian Supreme Command, and the territory of Serbia was divided into occupation zones, including Belgrade and the surrounding areas. The Austro-Hungarian occupation was accompanied by both repression and attempts to somehow normalize life - the occupiers tried to control the situation through the military and intelligence services, as well as through the construction of new schools and entertainment venues
The idea of uniting the Slavic peoples around Serbia, proclaimed by the Skupština (parliament) as a war aim in 1914, was deeply rooted not only among the Serbian political and intellectual elite, but also among the broad masses of the people, and this idea was in the air long before the outbreak of World War I. Thus, the leader of the People's Radical Party of Serbia, Nikola Pašić* (1845–1926) already claimed in 1894 that:
In 1878, after Serbia gained independence, its army became very influential, and under Russian patronage, Serbia became the center of the South Slav movement, and the annexation of Bosnia and Herzegovina from the Ottoman Empire by Austria-Hungary in 1908 only strengthened Serbian nationalism.

Sarajevo residents read a poster announcing the annexation of Bosnia and Herzegovina, 1908. In 1908, Austria-Hungary formally annexed Bosnia and Herzegovina, territories it had ruled since the Congress of Berlin in 1878. The event, known as the Bosnian Crisis, was strongly resisted by Serbia and other Slavic groups, who saw it as a threat to their aspirations.
Researchers studying this period write about a real war psychosis – in Serbia everything happened under the sign of preparation for the liberation war and further unification: the Church, education, the press and literature, all of this prepared public opinion for the upcoming liberation war. And Serbian scientist Jovan Cvijić* categorically stated:
Note. At the turn of the century, about twelve million people lived in the territory of the future Yugoslavia, most of whom were southern Slavs. But there were also other ethnic, linguistic and religious groups - Turks, Albanians, Germans, Magyars, Jews, Gypsies, Vlachs and others, professing various religions: Orthodoxy, Catholicism and Islam.
Simply put, the majority of the population living at the turn of the century in what would later be called Yugoslavia were southern Slavs, related to each other by language and culture, that is, according to today's categories, they were Slovenes, Croats, Serbs, Bosnian Muslims, Montenegrins and Macedonians. And even despite the extreme differences between religious denominations - Catholics, Orthodox and Muslims - the southern Slavs still intuitively felt a cultural affinity - they could communicate freely with each other, because Croats, Serbs, Montenegrins and Bosnians speak the same language.
Formation of the Kingdom of Serbs, Croats and Slovenes
So, the World War was coming to an end, and before the Entente decided to wipe Austria-Hungary off the map of Europe, 33 Balkan deputies in the Vienna Parliament called for the unification of the southern Slavs, and on October 6, 1918, the People's Committee of Slovenes, Croats and Serbs was formed in Zagreb with the aim of taking over the reins of power at the moment of the collapse of Austria-Hungary.

The Balkan States before World War I. Before World War I, the Balkan Peninsula was a region of intense political instability and nationalism, with various ethnic groups fighting for independence and influence from the weakened Ottoman Empire. This unstable situation, often referred to as the "Balkan Powder Keg," was one of the major factors that contributed to the outbreak of the war.
This Committee advocated the unification of Serbs, Croats and Slovenes on the condition that the Constitutional Assembly decides on the form of government (republic or monarchy) by a two-thirds majority, and during the interregnum two governments are temporarily formed: the government of the Kingdom of Serbia and the People's Committee of Slovenes, Croats and Serbs.
Note. In 1917, another rival South Slav group was formed, consisting of members of the Austro-Hungarian parliament and government, who also advocated a union of Croats, Slovenes and Serbs, but under Austrian leadership – the Habsburgs had long seen themselves in some role as protectors of the Slavic peoples and “gatherers” of the Slavic lands. The Serbs and the South Slav Committee then went further, signing an agreement to create an independent Kingdom of Serbs, Croats and Slovenes under Serbian kings, including those lands currently under Austria-Hungary. When the Habsburg monarchy collapsed under the pressure of war, the Committee of Serbs, Croats and Slovenes declared itself the ruler of the Slavs of the collapsed Austria-Hungary, which pushed it toward union with Serbia. It should be noted here that the newly created state was seen as a “reward” for Serbia’s own war of liberation, or, in common parlance, as its “war booty.” Such a centralized and unitary state guaranteed Serbia’s dominance..

Then Prince Regent Alexander I and French President Raymond Poincaré. In 1916, Serbian Prince Regent Alexander I and French President Raymond Poincaré visited the Verdun front. The visit was aimed at strengthening morale and demonstrating solidarity between Serbia and France. Alexander I was the Prince Regent of Serbia and acted on behalf of his ailing father, King Peter I. He served as Supreme Commander-in-Chief of the Serbian Army during World War I.
Serbia's Entente allies, given the material losses and enormous human sacrifices the country had suffered in World War I, agreed to the creation of a united South Slav state and allowed the rival groups to form it. Negotiations followed, in which the National Committee gave in to Serbia and the Yugoslav Committee, allowing Prince Regent Alexander I Karadjordjevic to proclaim the Kingdom of Serbs, Croats and SlovenesAt this stage, the devastated and war-torn region was held only by the army, which suppressed bitter rivalries between ethnic groups until borders were established.

Map of the Kingdom of Serbs, Croats and Slovenes after World War I. After the war and the collapse of the Austro-Hungarian Empire, the Kingdom of Serbia more than doubled in size to become the Kingdom of Serbia, Croatia and Slovenia. While the kingdom was known by that name in its early years, it became widely known as Yugoslavia (or variations such as "Yugo-Slavia") in 1922, officially changing its name to the Kingdom of Yugoslavia in 1929. With the unification of the South Slavic lands into a single kingdom, the capital remained in Belgrade and most of the power was in Serbia, with King Alexander earning the nickname "the Unifier." But here's the interesting thing: all of the united nations denied the existence of the Bosnians, considering them "Serbs and Croats who converted to Islam."
The state thus created was larger than an enlarged Serbia – it was an authoritarian monarchy, in which all powers belonged to the monarch, where absolutism was reflected in centralism at the state level and in the unitary, “Yugoslavism» at the national level.

King Alexander I meets King Ferdinand I of Romania as part of the Little Entente, which faded into political irrelevance in April 1937. The monarchs were prominent figures in their countries during an important period in European history. Prince Regent Alexander I of Yugoslavia, also known as Alexander I Karadjordjevic, reigned from 1921 to 1934. King Ferdinand I of Romania reigned from 1914 to 1927. Both kings played key roles in the complex political landscape of the Balkans, and their countries faced similar challenges of nationalism, ethnic tensions, and regional power dynamics.
The Kingdom of Serbs, Croats and Slovenes was distinguished by its extreme heterogeneity. The state with a population of 11 people, according to the 984 census, was deeply divided, and not only along ethnic and religious lines – the subjects of this new state had experienced various forms of government with various state institutions throughout its history, and the populations of the regions differed sharply from each other in economic and cultural development, so against this background, centralism and absolutism of power became the only alternative for the state...

Sarajevo. In the 20s and 30s, Sarajevo underwent significant changes following World War I and the subsequent establishment of the Kingdom of Yugoslavia. The city, previously under Austro-Hungarian rule, came under Yugoslav rule, which brought about changes in political, social and cultural life. But this period also saw an increase in nationalist tensions, especially between Serbs and Croats, which later contributed to instability throughout the region. The Belgrade regime became increasingly centralized with each passing year, causing resentment among the non-Serb population, which had initially welcomed the creation of the new state. Sarajevo in the 20s and 30s was essentially a city in transition, dealing with the aftermath of World War I, the establishment of the new state and rising nationalist sentiments, while maintaining a dynamic, if complex, multicultural environment. And even despite the growing tensions, a certain level of multiculturalism remained in Sarajevo, where different ethnic and religious groups coexisted and interacted.
When entering the union state, each side had its own interests, political parties began to form on the basis of ethnic communities, and at the everyday level, friction between nationalities was expressed in statements such as “Serbs want everything" and only "the croats will ruin everything».

Streets of Zagreb. In the 20s and 30s, Zagreb experienced significant changes and developments, especially in architecture and national identity. It was a period of vibrant cultural and artistic life and political changes, and the city itself became a center of modern architecture, with a vibrant social scene, elegant hotels, cafes, and places to “see and be seen.” But this period also saw tensions between supporters of Croatian autonomy and supporters of Serbian centralization, which later led to the formation of a Croatian puppet state under Axis rule during World War II.
In 1919, the Communist Party of Yugoslavia was formed, which received a large number of votes (58 mandates), but refused to join the parliament and was soon banned (according to the Law on the Protection of the State), and in 1921 a new government was formed and a new constitution was adopted, which defined the Kingdom of Serbs, Croats and Slovenes as a "constitutional, parliamentary and hereditary monarchy", the ideological basis of which was "Yugoslavism".

Ljubljana. In the 20s and 30s, Ljubljana underwent significant changes, especially under the influence of the architect Jože Plečnik (1872–1957), who had a significant impact on the urban landscape of Ljubljana in this period. In 1929, after the formation of Yugoslavia, Ljubljana became the capital of the Drava Banovina (which existed between 1929 and 1941 and was named after the Drava River), a region within the Kingdom of Yugoslavia corresponding to areas with a Slovene majority. After the end of World War I, the University of Ljubljana, founded in 1919, further strengthened the city’s role as an educational centre. Other institutions, such as the National University Library and the Slovenian Academy of Sciences and Arts, also contributed to the city’s intellectual life.
However, by all provisions the king had power and control over the people's representation - he was the one who convened the National Assembly and authorized its dissolution. The king sanctioned all laws and was the commander-in-chief of the armed forces. He represented the state abroad, appointed ministers who were fully accountable to him and the National Assembly. In a word, the declared parliamentarism was nothing more than decoration.

Skopje is a city with a rich history, located in the Vardar River Valley. In the 1920s and 1930s, Skopje underwent significant changes as part of the Kingdom of Yugoslavia. It was the capital of the Vardar Banovina (named after the Vardar River), one of the nine provinces of Yugoslavia, and experienced a period of modernization and development. As part of the KSKS, and later Yugoslavia, the city was the center of the formation of Macedonian national identity, through the standardization of the Macedonian language and the establishment of the Macedonian Orthodox Church. In the 20s and 30s, a university, media, and an academy of sciences were founded in Skopje, contributing to the intellectual and cultural life of the city. Skopje was also of strategic importance to Yugoslavia, due to its location on the border with Greece, Bulgaria, and Albania, making it important for the country's regional interests. By 1931, Skopje's population had increased to 64, indicating the city's growth and development, but the region nevertheless remained relatively poor and heavily dependent on royal investment from Belgrade, where the king, at the suggestion of the Council of Ministers, imposed a ban for four years.
Note. Yugoslavism is an ideology that emerged in the 30s in Croatia, which was part of the Habsburg Monarchy at the time. Yugoslavism is based on the idea that the southern Slavs – Serbs, Croats, Slovenes, Macedonians, Bosnians and Bulgarians – belong to a single Yugoslav nation, historically divided by different circumstances, religions and dialects, which provided the basis for their cooperation and eventual political unification. The idea of Yugoslavism was very popular during the Ottoman and Austro-Hungarian Empires, as several ethnic groups and confessions of the southern Slavs began to consider themselves victims of foreign imperialism. The leaders of Yugoslavism even published the following declaration:

This is how some "Yugoslavists" saw Yugoslavia. Albania and Bulgaria are included in this state
With the exception of Serbia, the newly formed state had no tradition of parliamentarism – none of the political parties were ready for dialogue, compromise or agreement, and due to serious dissatisfaction with the policies of the state-forming Serbian circles, nationalism began to spread widely among the South Slavic peoples. There were a great many political parties in the country, and all of them were nationalist, and also had their own paramilitary organizations, which were the main subjects of political violence.

Belgrade in the 20s. In record time, the capital acquired new boulevards, apartment buildings, prestigious government buildings, and the lifestyle of Belgraders began to resemble that of their European counterparts. Many educational and scientific institutions, sports associations and civil societies that existed before the war resumed their activities, and many new ones were created. It was a decade in which regular urban transport was established, and public peace and safety were occasionally disturbed by reckless drivers.
The confrontation between the political parties reached its climax on June 20, 1928, when the National Assembly became the scene of bloodshed, where in the middle of parliament, Radical Party MP Puniša Račić fired at Croatian MPs, killing Pavle Radić and Djuro Basariček and seriously wounding Ivan Pernar, Ivan Granda and Stjepan Radić.*, the last undisputed Croatian leader, who died a few days later.

Puniš Račić shoots a member of parliament, June 20, 1928 Serbian MP from Montenegro Puriša Račić opened fire on Croat MPs sitting on the front benches of the Yugoslav parliament building. Immediately after the shooting of the Croatian MPs, Yugoslav parliamentarism collapsed, giving way to the open dictatorship of Prince Regent Alexander
These deaths in parliament at the hands of an assassin turned Croatian MPs into martyrs, and the Croatian Ustasha began to use the deaths of Radić and his fellow party members as proof of Serbian hegemony and as justification for their terrorist activities against the Serbs.

Belgrade in the 20s. After the First World War, Belgrade underwent a major reconstruction, becoming the capital of the newly created Kingdom of Serbs, Croats and Slovenes - in the 1920s, Belgrade's population increased dramatically, making it the most dynamic urban center of the new state, and this period was marked by both progress and difficulties, including rapid urbanization, reconstruction works and the influence of foreign capital, while the high demand for housing due to the population growth contributed to a boom in civil construction. It should be noted here that the newly formed Kingdom faced such serious problems as high inflation, a large budget deficit and a debt burden resulting from the war
Note. It was precisely during this period, after the murder of Stjepan Radić and a number of members of the Assembly and the further centralization of power in the hands of the Serbs and the king, that the separatist movement of the Ustaše (rebels) began to emerge in Croatia, led by Ante Pavelic, the future head of the Independent State of Croatia during World War II. This movement quickly gained strength, and was viewed with sympathy by Croatia's official political circles..
The King's Coup d'Etat
On January 6, 1929, six months after the murder of the Croatian deputies in the National Assembly, King Alexander I Karadjordjevic staged a coup d'état. After the First World War, dictatorial rule was not uncommon in Europe, so a state of emergency was declared in Belgrade, the country's parliament was easily dissolved, and a government headed by the commander of the palace guard, General Petar Zivkovic, came to power. In addition, the country received its new official name: "The Kingdom of Yugoslavia".

In 1933, a meeting between Yugoslavia's King Alexander I and Turkish President Mustafa Kemal Ataturk took place, symbolizing the strong diplomatic and political ties between the two countries at the time. The meeting took place against the backdrop of growing cooperation and friendship between Yugoslavia and Turkey. Both leaders were key figures in their countries, and their interaction marked a period of growing diplomatic and political rapprochement. The Serbian press of the time also gave wide coverage to the events in Turkey, reflecting the close friendship between King Alexander and Ataturk.
Unlike other European dictatorships, the king's dictatorship was caused by a sharp conflict between two ethnic groups - the Serbs and the Croats in the National Assembly, and, having worsened to the point of impossibility, not to mention the murder of deputies, this conflict formed the basis for the proclamation of his own dictatorship by King Alexander I on January 6.
Royal Manifesto to my dear people:
Well, the final stage of the state reorganization, which began with the king’s coup d’état, was September 3, 1931, when Alexander I granted the country a new constitution, which described Yugoslavia as a “constitutional monarchy with popular representation,” with the king exercising its legislative power.

A Jewish shop in Belgrade. The 30s. In the 20s and 30s, Yugoslavia was home to some 78 Jews, including some 000 foreign refugees fleeing persecution in other countries. They were a diverse group, with both Sephardic (4000%) and Ashkenazi (40%) communities, with varying degrees of integration into Yugoslav society. Most lived in cities and constituted about 60 percent of the population. The Sephardim living in Bosnia were considered an indigenous element, given special rights by four centuries of living in the region. In Serbia, the loyalty of the Jews, many of whom had fought bravely in the Serbian army in World War I, was also never questioned – they were considered “one of our own” and spoke Serbian (Ladino had largely been forgotten). Ashkenazi Jews from Croatia, Slovenia and Vojvodina spoke German and Hungarian and were considered more alien than Sephardic Jews
But, unfortunately, the king's good intentions to unite the Yugoslav society, torn apart by ethnic and religious conflicts, remained unfulfilled due to the onset of the global economic crisis that the Kingdom of Yugoslavia faced.

Streets of Belgrade in the 20s and 30s. This period was also one of political instability with frequent changes of government, and Belgrade was a combination of traditional and modern elements, with the so-called "golden twenties" had a profound impact on the city, while a significant portion of the population still lived in poverty
The socially and economically poor country, exhausted by two Balkan wars and then the World War that followed, was in a dire economic situation – almost half a million of its citizens were standing in lines for free bread. Here is how the British Ambassador to Yugoslavia Howard William Kennard described the impact of economic difficulties on the political situation that had developed in the country:

In addition to the economy, the 1920s were also marked by significant changes in the cultural and social life of Belgrade. To sum up, the 1920s in Belgrade were a period of significant economic and urban transformation, but were also marked by problems related to post-war reconstruction, political instability and social inequality. Although the 20s in Belgrade were a period of significant economic and urban transformation, they were also marked by problems related to post-war reconstruction, political instability and social inequality. The transformation of the new capital was largely due to mass immigration during the city’s reconstruction – during this period, the population more than doubled, and by the end of the decade, Belgrade had almost 240 permanent residents.
The Killing of the King
National tensions in Yugoslavia began to take on increasingly threatening proportions, and in 1934, Alexander I, while on a state visit to France, where he tried to enlist the support of the Little Entente against the encroachments of Hungary and Italy on the South Slavic lands, was assassinated by a certain Vlado Chernozemsky, a member of the Macedonian revolutionary organization, behind which stood the Croatian Ustasha. The French Foreign Minister Louis Barthou also died along with the king.

On October 9, 1934, Yugoslavia's King Alexander I and French Foreign Minister Louis Barthou were assassinated while on a state visit in Marseille. The assassination attempt, carried out by a member of the Internal Macedonian Revolutionary Organization (IMRO), also resulted in Barthou's death, wounded by a bullet during the attempt. The assassination attempt was organized by Ante Pavelić, the leader of the Croatian Ustaše. The terrorist attacked as the king's motorcade moved slowly toward the city center, to the sound of thousands of cheers from onlookers. Lieutenant Colonel Jules Piollet, who was part of the king's French entourage, struck the assassin over the head with a sabre, after which the angry crowd threw him to the floor. The man later died of his wounds, so disfigured that only his passport and a skull and crossbones tattoo provided clues to his identity.
This vile murder caused another redistribution of political forces in the country - fearing the disintegration of Yugoslavia under the pressure of ever-increasing Croatian separatism, the Yugoslav government gives in to the demands of the Ustasha, after which Croatia receives autonomy, which leads to an even stronger growth of mutual national intolerance in the kingdom.

After the assassination of King Alexander I, in accordance with his will, a regency regime was established for the minority of the 11-year-old heir to the throne, Peter II, where the regent was the cousin of the murdered king, Pavel Karageorgevich, who led Yugoslavia towards rapprochement with National Socialist Germany and fascist Italy, turning away from traditional friendship with France.

In 1934, he succeeded to the throne under the regency of Prince Paul, after the assassination of his father King Alexander I in Marseille. In March 1941, Peter II took over the throne after the revolution that began due to the pro-fascist orientation of Prince Regent Paul. However, a few weeks later, Hitler conquered Yugoslavia, and Peter was forced to seek refuge in Greece, and after Marshal Tito came to power, he was in exile in England and France.
Regency
Unlike the murdered King Alexander I, who was considered a conservative, Prince Regent Paul appointed Milan Stojadinović (1935-1939) as Prime Minister, who acted as a modernist and reformer, but was still committed to the policy of strict centralism and integral “Yugoslavism”, however, the peoples that were part of the Yugoslav state were becoming more and more disillusioned with the “Yugoslavism” imposed on them in any of its forms.

Prince Regent Paul Karadjordjevic. Born in 1893, Prince Paul was the elder brother of the assassinated King Alexander I, and according to the assassinated king's will, he and two other regents were to act as tutors to the young Prince Peter, then aged 11 and who would come of age at 18 in September 1941. The regent's mother was Russian, of the House of Demidov, and his cousin was the Crown Prince of Serbia. Prince Paul was educated in Switzerland and Belgrade, and in 1910 went to study philosophy and literature at Oxford University in London. However, his studies were interrupted four times by the three Balkan Wars that preceded and then by World War I itself. He is fluent in French and English. His only son was born in 1924. Throughout his regency he played a careful double game between the British and French allies, whom he secretly admired, and the Nazis and Italian fascists, whom he openly feared.
Even Prime Minister Stojadinovic's attempt to reach an agreement between the Vatican and the Serbian Orthodox Church for the sake of religious harmony in the country did not help.

Milan Stojadinović (1888–1961) – Prime Minister of Yugoslavia. After the assassination of King Alexander Karađorđević, Prince Regent Paul and his Prime Minister Milan Stojadinović took on the difficult task of calming the country’s internal crisis caused by Croatian separatism and ensuring external security against revisionist neighbors. In that international situation, Stojadinović adhered to a friendship treaty with Italy, whose Foreign Minister Galeazzo Ciano had a strong sympathy for Stojadinović and believed that he was a fascist at heart. He died in Argentina in 1961
The Cvetkovic Government
On 5 February 1939, Prince Regent Paul dismissed Milan Stojadinović's cabinet and entrusted the post of Prime Minister to an obscure politician, Dragiša Cvetković, whose main task was to conclude an agreement with the Croats. The Prince Regent was concerned that, with the assistance of the increasingly powerful Nazi Germany, the independence of Slovakia, achieved with German assistance in 1938, could affect Croatia, where the desire for autonomy had generated a strong national movement, ignoring which threatened the greatest problem for the state.

Prime Minister of Yugoslavia Dragiša Cvetković (1893–1969). Cvetković was the Prime Minister of Yugoslavia from 1939 to 1941. In this position, he was relatively successful in controlling the various warring ethnic groups in the kingdom. However, after he signed the treaty aligning Yugoslavia with the Axis alliance on 25 March 1941, the gulf between the Serbs (who were pro-British) and the Croats (who were pro-German) became even more acute. On 4 September 1944, with the Soviets approaching, he fled to Bulgaria and then Turkey. Branded a traitor, he spent the rest of his life in Paris, France. On 25 September 2009, the District Court of his hometown of Niš acquitted him. Pictured right: Yugoslav Prime Minister Dragiša Cvetković talks with Third Reich Foreign Minister Joachim von Ribbentrop, 25.03.1941 March XNUMX.
Agreement between Prime Minister Dragisa Cvetkovic and Croatian political leader Vlatko Maček* was achieved almost immediately, but time for its implementation was quickly running out. The agreement was signed on August 26, 1939, just a couple of days before the outbreak of World War II. The agreement created the first autonomous administration in Yugoslavia, with its seat in Zagreb. One can only guess what course it would have taken if World War II had not occurred...

The newspaper "Jutarnji list" reporting on the signing of the agreement
But the creation of the Croatian Autonomy did not resolve acute national issues, primarily between the Serbs and the Croats. As a result of the Cvetkovic-Maček agreement, large territories with a Serbian population of over 800 people became part of the Croatian Autonomous Region, which led to a new round of tension between the Serbs and the Croats.

The share of foreign capital in the regions of Yugoslavia. Although agriculture in the country remained important, new industries and the service sector were actively developing in the city, and the influence of foreign financial institutions increased in the banking sector. The government made efforts to stabilize the dinar, including the introduction of the gold standard, which again required foreign borrowing
Territory of Croatian Autonomy (banovinas) included modern Croatia, except for some areas of the Adriatic coast that were then part of Fascist Italy, and about 40% of Bosnia and Herzegovina. Having pacified Croatia somewhat, the Cvetkovic-Maček agreement triggered a chain reaction in other ethnic regions – Serbia, Slovenia and Bosnian Muslims began demanding exactly the same autonomy for themselves.
Originating from Serbia and led by the legal theorist and historian Slobodan Jovanović (1869–1958), the Cultural Club* gathered around itself the entire intellectual and political elite of Serbia. This "Club" advocated autonomy (banovina) for all "Serbian territories" - Bosnia, Montenegro and Macedonia, and was close to the historical concept of "Greater Serbia". Thus, it can be said that 1939 put an end to Yugoslav centralism...
Joining the Tripartite Pact
As is known, on September 1, 1939, the Second World War began with the attack of Nazi Germany on Poland. But this war for a little over a year and a half had not yet directly affected Yugoslavia, but the situation of the steadily expanding fascist aggression of Germany and Italy and the military conflagration in Europe led to an increasing increase in the danger for the Yugoslav state, and in addition, Germany, after the annexation of Austria, became Yugoslavia's immediate neighbor.

This photograph was taken in June 1939 during Prince Paul's official visit to Berlin, when the reigning monarch, King Peter II, was still a minor. It was yet another attempt to sway Yugoslavia to the Axis side, which Paul had successfully resisted since 1934 (until the situation became unbearable in April 1941).
The Cvetkovic government was seriously concerned about averting the possible threat of Yugoslavia being drawn into a military conflict, and three days after the start of World War II, the country's leadership hastened to issue a statement about the complete neutrality of the Yugoslav kingdom.
Forced to make concessions in domestic policy, including the agreement on autonomy with the Croats, concluded for the sake of the country's territorial integrity, Prince Regent Pavel Karadjordjevic, guided by the same idea of integrity, finally chose a foreign policy course that put an end to the apparent neutrality of the Kingdom of Yugoslavia, maneuvering in every possible way.

German Chancellor Adolf Hitler ceremoniously greets Prince Regent Paul Karadjordjevic at the train station. Prince Regent Paul's foreign policy, including the signing of the Tripartite Pact, was dictated by a desire to give Yugoslavia as much freedom of action as possible in extremely unfavorable circumstances. After the fall of France and the evacuation of British troops, Prince Paul saw no other way to save Yugoslavia than by adopting a policy of compromise with the Axis powers. After the end of the war, the communist authorities of Yugoslavia declared Paul an enemy of the state - he was forbidden to return to Yugoslavia and all his property was confiscated. He died in Paris on September 14, 1976, at the age of 83. He was rehabilitated by a Serbian court in 2011 and reburied in the family crypt at the Royal Mausoleum in Oplenac, Serbia.
In his conversations with the German ambassador in Belgrade, Prince Regent Pavel Karadjordjevic repeatedly pointed out the need for close Yugoslav-German cooperation, especially in trade and economic matters, in which Germany was very interested – in order to obtain food and raw materials for industry from Yugoslavia, especially non-ferrous metal ores. Being an Anglophile, Prince Regent Pavel believed that Yugoslavia’s friendship with Berlin could protect the kingdom from war, and Hitler, who was preoccupied at the time with preparing an attack on the USSR, combined tolerance and pressure in his attitude towards Yugoslavia.

German Foreign Minister Joachim von Ribbentrop and Yugoslav Prime Minister Dragiša Cvetković sign the Tripartite Agreement. On March 25, 1941, by decision of the Royal Council, Prime Minister Dragiša Cvetković and Foreign Minister Aleksandar Cincar-Marković signed a protocol in the Belvedere Castle in Vienna on Yugoslavia's accession to the Axis Tripartite Pact, and two days later, on March 27, a group of officers carried out a military coup, overthrew the government, declared King Peter II of age and transferred power to him
And finally, on March 25, 1941, in Vienna, Dragiša Cvetković and Aleksandar Cincar Marković (Minister of Foreign Affairs) signed the Tripartite Pact.

German Foreign Minister Joachim von Ribbentrop delivers a speech after signing the Tripartite Pact. The agreement was reached after months of negotiations between Germany and Yugoslavia by German Foreign Minister Joachim von Ribbentrop and Yugoslav Prime Minister Dragisa Cvetkovic. Under the treaty, the Axis powers pledged to respect the sovereignty and territorial integrity of Yugoslavia.
That same day, riots broke out in Belgrade, quickly spreading throughout Serbia. Communists and anti-fascist activists were behind these riots, and the protesting masses, recalling the First World War, revived their anti-German sentiments. The mass "no" to the union with the German Reich was evident from the slogans shouted by the protesters: "Down with the government!", "Long live the union with the Soviet Union!", "Better a grave than a slave!" and "Better war than a pact!".

In March 1941, Yugoslavia experienced serious unrest, culminating in a military coup. This unrest was largely caused by the government's decision to sign the Tripartite Pact with the Axis powers on 25 March, allying the country with Germany, Italy and Japan in a military alliance. This move sparked widespread protests and eventually led to a coup d'état on 27 March, which overthrew the incumbent Cvetkovic government.
In this situation, on the night of March 26-27, 1941, Air Force Generals Borivoje Mirkovic and Dusan Simovic staged a coup d'état. The young King Peter II declared himself of age. General Dusan Simovic was appointed Prime Minister and Vlatko Maček was appointed Vice Prime Minister. Only one person died in this military coup, and the military forces participating in it occupied all the main government institutions in Belgrade within two hours of the night and surrounded the royal court, encountering almost no serious resistance.

General Dusan Simovic – Prime Minister of Yugoslavia. Immediately after the coup that overthrew the government of Dragiša Cvetković, General Dusan Simovic (1882–1962) served as Prime Minister of Yugoslavia from 27 March 1941 to 12 January 1942. Simovic's premiership was short-lived, as Yugoslavia was occupied by Nazi Germany on 6 April 1941, the day of his daughter's wedding. He subsequently headed the Yugoslav government-in-exile, first in Jerusalem and then in London, until he was replaced by Slobodan Jovanovic in January 1942. After the end of the war, Peter II appointed Simovic as head of the Yugoslav government, but Josip Broz Tito refused to support him, and Simovic resigned in May 1945. The communist authorities were quite lenient towards Simovic after he returned to his homeland in 1952, where he was granted a general's pension.
Germany's opponents responded to this coup with enthusiasm - for Winston Churchill, the coup d'état in Yugoslavia was evidence that the Kingdom of Yugoslavia, in his words, "found its soul", and Hitler saw this as a brazen challenge to Germany in the midst of preparations for war against the USSR. In his appeal to the German people on April 6, 1941, Hitler declared:
Here is what the British military historian Antony Beevor writes:
Note. In post-war historiography, suspicions began to appear that the NKVD may have also been aware of the preparation of this coup, and may have influenced it. For example, according to General Pavel Sudoplatov, in his memoirs published after the war, Soviet intelligence actively assisted the conspirators by sending a group of its employees to Belgrade. There is also an opinion that the coup was carefully planned and financed by British intelligence, and that British intelligence services had been in contact with opposition forces long before the putsch, but there is no evidence for this...

German invasion of Yugoslavia. In April 1941, Germany, along with its allies Italy, Hungary and Bulgaria, invaded Yugoslavia. The attack on Yugoslavia was swift and brutal, an act of terror that resulted in the deaths of 17 civilians, the highest civilian death toll in a single day since the war began. To make matters worse, residents of nearby towns and villages had flocked to the capital to celebrate Palm Sunday. All Yugoslav airfields were also bombed, destroying most of the 000 aircraft on the ground. The invasion, which began on 600 April, was a swift and decisive victory for the Axis powers, culminating in the unconditional surrender of the Royal Yugoslav Army on 6 April.
Early in the morning of April 6, 1941, Hitler's Germany attacked Yugoslavia and Greece at the same time without declaring war. The Wehrmacht invaded Yugoslavia from three directions simultaneously - Bulgaria, Austria and Hungary, and the beginning of this invasion was accompanied by massive bombing of Yugoslav military and communication facilities. The most important communication lines were put out of action, and the already small and outdated Yugoslav army was destroyed on the ground. aviation.

Belgrade after the bombing. Around 7:00 a.m., the first waves of German bombers flew over Belgrade and dropped their deadly cargo. There was practically no serious defense – weak anti-aircraft fire was conducted for some time, several Yugoslav fighters took off and entered into air battles, but were put out of action in the shortest possible time. The entire city was easy prey for German bombers. Source: Belgrade National Library
Belgrade suffered greatly, with barbaric bombings resulting in extensive destruction and significant civilian casualties (according to various estimates, between 2000 and 30 people died).

The bombings mainly targeted residential and business areas where there were no military targets. The attack, which included four waves of bombing, caused significant damage to infrastructure, including the destruction of bridges over the Sava and Danube rivers, as well as the loss of vital transportation networks. The National Library, one of Belgrade's most important cultural institutions, was also destroyed, with hundreds of thousands of books and manuscripts lost. Source: Belgrade National Library
The Germans entered Zagreb on April 10, 1941. After Vlatko Maček* refused the post of prime minister of Croatia under German protectorate, it was proclaimed Independent State of Croatia, and the Ustasha came to power. Croatia was ruled by a militia, an army, a secret police and a system of concentration camps – there were twenty of them, and the Ustasha principles of an ethnically pure state, proclaimed by the Ustasha back in 1933, reigned in the country.

German troops enter Zagreb. In April 1941, Zagreb became the capital of the Independent State of Croatia (NDH), a puppet state created by the Ustasha, a Croatian nationalist organization that closely collaborated with the Axis powers. This followed the German invasion of Yugoslavia, which began on April 6, and on April 10, Slavko Kvaternik, a prominent Ustasha representative, proclaimed the establishment of the NDH in Zagreb. The city became the administrative center of the new state under the Ustasha regime.
And on April 13, 1941, Belgrade fell, which was facilitated in no small measure by numerous supporters of the fifth column, spreading defeatist sentiments and anti-war propaganda. The Kingdom of Yugoslavia finally ceased to exist on April 17, 1941, when its army, which had fought for eleven days, capitulated, and the bearers of the Yugoslav supreme power were in exile...
After the complete occupation of Serbia, in August General Milan Nedić was appointed Prime Minister of the so-called Government of National Salvation, but his administration differed from the administration in Norway and France in that in Serbia the Germans held all the main levers of power in their hands. In Serbia the Germans created a system of concentration camps, where out of 75 Jews according to the 000 census only 1940 survived the war.

In 1941, Milan Nedić (1887–1946) was a key figure in Serbia during the German occupation, heading the collaborationist Government of National Salvation. He initially commanded the 2nd Army Group during the Axis invasion of Yugoslavia, but was captured by the Germans. He was later released and allowed to return to Belgrade. On 29 August 1941, the German military commander in Serbia appointed Nedić as prime minister.Governments of National Salvation"This puppet government collaborated with the occupation forces, particularly the Germans, in administering the occupied territory.
Note. In July 2008, a group of Serbian citizens filed a petition with the Belgrade District Court seeking the posthumous rehabilitation of Milan Nedić, whom the plaintiffs considered a "victim of persecution and violence for political reasons." In a 2014 ruling, the higher court rejected the petition for judicial rehabilitation of Milan Nedić. Today, Milan Nedić, the head of the Axis collaborationist regime in Serbia during World War II, remains attractive to some Serbs and therefore controversial, with claims that he sought to save Serbs from a worse fate. In 1946, he committed suicide by jumping out of a window...
This is how L. Ya. Gibiansky from the Institute of Slavic Studies describes the negotiations between Serbian collaborators and the German occupation authorities about the future structure of Serbia:
After the dismemberment of Yugoslavia, Montenegro received the status of an Italian protectorate, and Slovenia was divided between Germany, Italy and Hungary. The history of the Kingdom of Serbs, Croats and Slovenes from 1918 to 1929 and the Kingdom of Yugoslavia from 1929 to 1941 was short: only twenty-three years.
The People's Liberation War was ahead...
