Yugoslavia (; lit. 'Land of the South Slavs') was a country in Central Europe and the Balkans that existed from 1918 to 1992. It came into existence following World War I, under the name of the Kingdom of Serbs, Croats and Slovenes, from the merger of the Kingdom of Serbia with the provisional State of Slovenes, Croats and Serbs, and constituted the first union of South Slavic peoples as a sovereign state, following centuries of foreign rule over the region under the Ottoman Empire and the Habsburg monarchy.
Under the rule of the House of Karađorđević, the kingdom gained international recognition on 13 July 1922 at the Conference of Ambassadors in Paris and was renamed the Kingdom of Yugoslavia on 3 October 1929. Peter I was the country's first sovereign. Upon his father's death in 1921, Alexander I went on to rule the country through an extended period of political crisis that culminated in the 6 January Dictatorship and, ultimately, his assassination in 1934. Prince Paul headed the state as a prince regent until Alexander's son Peter II was declared of-age, which happened following the Yugoslav coup d'état in March 1941. Alexander I was the longest reigning of the three Yugoslav monarchs.
The kingdom was invaded and occupied by the Axis powers in April 1941, marking the start of World War II in Yugoslavia. The Communist-led Partisan resistance went on to proclaim the Democratic Federal Yugoslavia and acquire the backing of the Allies at the Tehran Conference in late November 1943. In 1944, King Peter II, then living in exile, gave his recognition to the Anti-Fascist Council for the National Liberation of Yugoslavia as the legitimate government. In November 1945, after the war ended, the regency council appointed by the King called a parliamentary election that established the Constituent Assembly of Yugoslavia. The Constituent Assembly proclaimed Yugoslavia a federal republic on 29 November 1945, thus abolishing monarchical rule. This marked the onset of a four-decade long uncontested communist party rule of the country. The newly proclaimed Federal People's Republic of Yugoslavia acquired the territories of Istria, Rijeka, and Zadar from Italy. Partisan leader Josip Broz Tito ruled the country from 1944 until his death in 1980, first as the prime minister and later as the president. In 1963, the country was renamed for the final time, as the Socialist Federal Republic of Yugoslavia (SFRY).
The six constituent republics that made up the SFRY were the socialist republics of Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slovenia. Within Serbia were the two socialist autonomous provinces, Kosovo and Vojvodina, which, following the adoption of the 1974 Yugoslav Constitution, were largely equal to the other members of the federation. After an economic and political crisis and the rise of nationalism and ethnic conflicts following Tito's death, Yugoslavia broke up along its republics' borders during the Revolutions of 1989, at first into five countries, leading to the Yugoslav Wars. From 1993 to 2017, the International Criminal Tribunal for the former Yugoslavia tried political and military leaders from the former Yugoslavia for war crimes, genocide, and other crimes committed during those wars.
After the breakup, the republics of Montenegro and Serbia formed a reduced federative state, the Federal Republic of Yugoslavia (FRY). This state aspired to the status of sole legal successor to the SFRY, but those claims were opposed by the other former republics. Eventually, it accepted the opinion of the Badinter Arbitration Committee about shared succession and in 2003, its official name was changed to the State Union of Serbia and Montenegro. This state dissolved when Montenegro and Serbia each became independent states in 2006, with Kosovo having an ongoing dispute over its declaration of independence in 2008.
Background
The concept of Yugoslavia, as a common state for all South Slavic peoples, emerged in the late 17th century and gained prominence through the Illyrian Movement of the 19th century. The name was created by the combination of the Slavic words jug ("south") and Slaveni/Sloveni (Slavs). Moves towards the formal creation of Yugoslavia accelerated after the 1917 Corfu Declaration between the Yugoslav Committee and the government of the Kingdom of Serbia.
Kingdom of Yugoslavia
The country was formed in 1918 immediately after World War I as the Kingdom of Serbs, Croats and Slovenes by union of the State of Slovenes, Croats and Serbs and the Kingdom of Serbia. It was commonly referred to at the time as a "Versailles state". Later, King Alexander I renamed the country Yugoslavia in 1929.
Austria-Hungary collapsed after World War I in 1918. Bačka, Banat and Baranja were annexed, and the Podgorica Assembly led to the unification of the Kingdom of Montenegro into Serbia. Međimurje was occupied and held by the Yugoslav forces, and Prekmurje was occupied twice before it was held. The subsequent Treaty of Trianon in 1920 formally ceded the northern territories from Hungary to Yugoslavia.
King Alexander's rule
On 20 June 1928, Serb deputy Puniša Račić shot at five members of the opposition Croatian Peasant Party in the National Assembly, resulting in the death of two deputies on the spot and that of leader Stjepan Radić a few weeks later. On 6 January 1929, King Alexander I got rid of the constitution, banned national political parties, assumed executive power, and renamed the country Yugoslavia. He hoped to curb separatist tendencies and mitigate nationalist passions. He imposed a new constitution and relinquished his dictatorship in 1931. However, Alexander's policies later encountered opposition from other European powers stemming from developments in Italy and Germany, where Nazis rose to power, and the Soviet Union, where Joseph Stalin became absolute ruler. None of these three regimes favored the policy pursued by Alexander I. In fact, Italy and Germany wanted to revise the international treaties signed after World War I, and the Soviets were determined to regain their positions in Europe and pursue a more active international policy.
Alexander attempted to create a centralised Yugoslavia. He decided to abolish Yugoslavia's historic regions, and new internal boundaries were drawn for provinces or banovinas. The banovinas were named after rivers. Many politicians were jailed or kept under police surveillance. During his reign, communist movements were restricted.
The king was assassinated in Marseille during an official visit to France in 1934 by Vlado Chernozemski, an experienced marksman from Ivan Mihailov's Internal Macedonian Revolutionary Organization with the cooperation of the Ustaše, a Croatian fascist revolutionary organisation. Alexander was succeeded by his eleven-year-old son Peter II and a regency council headed by his cousin, Prince Paul.
1934–1941
The international political scene in the late 1930s was marked by growing intolerance between the principal figures, by the aggressive attitude of the totalitarian regimes, and by the certainty that the order set up after World War I was losing its strongholds and its sponsors their strength. Supported and pressured by Fascist Italy and Nazi Germany, Croatian leader Vladko Maček and his party managed the creation of the Banovina of Croatia (Autonomous Region with significant internal self-government) in 1939. The agreement specified that Croatia was to remain part of Yugoslavia, but it was hurriedly building an independent political identity in international relations.
Prince Paul submitted to fascist pressure and signed the Tripartite Pact in Vienna on 25 March 1941, hoping to continue keeping Yugoslavia out of the war. However, this was at the expense of popular support for Paul's regency. Senior military officers were also opposed to the treaty and launched the Yugoslav coup d'état when the king returned on 27 March. Army General Dušan Simović seized power, arrested the Vienna delegation, exiled Prince Paul, and ended the regency, giving 17-year-old King Peter full powers. Hitler then decided to attack Yugoslavia on 6 April 1941, followed immediately by an invasion of Greece where Mussolini had previously been repelled.
World War II
At 5:12 a.m. on 6 April 1941, German, Italian and Hungarian forces invaded Yugoslavia. The German Air Force (Luftwaffe) bombed Belgrade and other major Yugoslav cities. On 17 April, representatives of Yugoslavia's various regions signed an armstice with Germany in Belgrade, ending eleven days of resistance against the invading German forces. More than 300,000 Yugoslav officers and soldiers were taken prisoner.
The Axis powers occupied Yugoslavia and split it up. The Independent State of Croatia was established as a Nazi satellite state, ruled by the fascist militia known as the Ustaše that came into existence in 1929, but was relatively limited in its activities until 1941. German troops occupied Bosnia and Herzegovina as well as part of Serbia and Slovenia, while other parts of the country were occupied by Bulgaria, Hungary, and Italy. From 1941 to 1945, the Croatian Ustaše regime persecuted and murdered around 300,000 Serbs, along with at least 30,000 Jews and Roma; hundreds of thousands of Serbs were also expelled and another 200,000-300,000 were forced to convert to Catholicism.
From the start, the Yugoslav resistance forces consisted of two factions: the communist-led Yugoslav Partisans and the royalist Chetniks, with the former receiving Allied recognition at the Tehran conference (1943). The heavily pro-Serbian Chetniks were led by Draža Mihajlović, while the pan-Yugoslav oriented Partisans were led by Josip Broz Tito.
The Partisans initiated a guerrilla campaign that developed into the largest resistance army in occupied Western and Central Europe. The Chetniks were initially supported by the exiled royal government and the Allies, but they soon focused increasingly on combating the Partisans rather than the occupying Axis forces. By the end of the war, the Chetnik movement transformed into a collaborationist Serb nationalist militia completely dependent on Axis supplies. The Chetniks also persecuted and killed Muslims and Croats, with an estimated 50,000-68,000 victims (of which 41,000 were civilians). The highly mobile Partisans, however, carried on their guerrilla warfare with great success. Most notable of the victories against the occupying forces were the battles of Neretva and Sutjeska.
On 25 November 1942, the Anti-Fascist Council of National Liberation of Yugoslavia was convened in Bihać, modern day Bosnia and Herzegovina. The council reconvened on 29 November 1943, in Jajce, also in Bosnia and Herzegovina, and established the basis for post-war organisation of the country, establishing a federation (this date was celebrated as Republic Day after the war).
The Yugoslav Partisans were able to expel the Axis from Serbia in 1944 and the rest of Yugoslavia in 1945. The Red Army provided limited assistance with the liberation of Belgrade and withdrew after the war was over. In May 1945, the Partisans met with Allied forces outside former Yugoslav borders, after also taking over Trieste and parts of the southern Austrian provinces of Styria and Carinthia. However, the Partisans withdrew from Trieste in June of the same year under heavy pressure from Stalin, who did not want a confrontation with the other Allies.
Western attempts to reunite the Partisans, who denied the supremacy of the old government of the Kingdom of Yugoslavia, and the émigrés loyal to the king led to the Tito-Šubašić Agreement in June 1944; however, Marshal Josip Broz Tito was in control and was determined to lead an independent communist state, starting as a prime minister. He had the support of Moscow and London and led by far the strongest Partisan force with 800,000 men.
The official Yugoslav post-war estimate of victims in Yugoslavia during World War II is 1,704,000. Subsequent data gathering in the 1980s by historians Vladimir Žerjavić and Bogoljub Kočović showed that the actual number of dead was about 1 million.
Federal People's Republic of Yugoslavia
On 11 November 1945, parliamentary elections were held with only the Communist-led People's Front appearing on the ballot, securing all 354 seats in the newly formed Constituent Assembly. On 29 November, the Constituent Assembly proclaimed the Federal People's Republic of Yugoslavia, thus abolishing monarchical rule. The elections were called by the regency council appointed by the King on 2 March 1945, though whether this represented an abdication is in dispute among historians. Marshal Tito was now in full control, and all opposition elements were eliminated.
The 1946 Constitution of the Federal People's Republic of Yugoslavia, modelled after the Constitution of the Soviet Union, established six republics, an autonomous province, and an autonomous district that were a part of Serbia. The federal capital was Belgrade. The policy focused on a strong central government under the control of the Communist Party, and on recognition of the multiple nationalities. The flags of the republics used versions of the red flag or Slavic tricolor, with a red star in the centre or in the canton.
Tito's regional goal was to expand south and take control of Albania and parts of Greece. In 1947, negotiations between Yugoslavia and Bulgaria led to the Bled agreement, which proposed to form a close relationship between the two Communist countries, and enabled Yugoslavia to involve itself in the civil war in Greece and use Albania and Bulgaria as bases. Stalin vetoed this agreement and it was never realised. The break between Belgrade and Moscow was now imminent.
Yugoslavia solved the national issue of nations and nationalities (national minorities) in a way that all nations and nationalities had the same rights. However, most of the German minority of Yugoslavia, most of whom had collaborated during the occupation and had been recruited to German forces, were expelled towards Germany or Austria.
Yugoslav–Soviet split and the Non-Alignment Movement
The country distanced itself from the Soviets in 1948 (cf. Cominform and Informbiro) and started to build its own way to socialism under the political leadership of Josip Broz Tito. Accordingly, the constitution was heavily amended to replace the emphasis on democratic centralism with workers' self-management and decentralization. The Communist Party was renamed to the League of Communists and adopted Titoism at its congress the previous year.
All the Communist European Countries had deferred to Stalin and rejected the Marshall Plan aid in 1947. Tito, at first went along and rejected the Marshall plan. However, in 1948 Tito broke decisively with Stalin on other issues, making Yugoslavia an independent communist state. Yugoslavia requested American aid. American leaders were internally divided, but finally agreed and began sending money on a small scale in 1949, and on a much larger scale 1950–53. The American aid was not part of the Marshall plan.
Tito criticised both Eastern Bloc and NATO nations and, together with India and other countries, started the Non-Aligned Movement in 1961, which remained the official affiliation of the country until it dissolved.
