Creation of Yugoslavia in the context of "Balkans"

The Balkans (/ˈbɔːlkənz/ BAWL-kənz, /ˈbɒlkənz/ BOL-kənz), corresponding partially with the Balkan Peninsula, is a geographical area in southeastern Europe with various geographical and historical definitions. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Musala, 2,925 metres (9,596 ft), in the Rila mountain range, Bulgaria.

The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of southeastern Europe spanning from the Adriatic Sea to the Black Sea. In the 19th century the term Balkan Peninsula was a synonym for Rumelia, the parts of Europe that were provinces of the Ottoman Empire at the time. It had a geopolitical rather than a geographical definition, which was further promoted during the creation of Yugoslavia in the early 20th century. The definition of the Balkan Peninsula's natural borders does not coincide with the technical definition of a peninsula; hence modern geographers reject the idea of a Balkan Peninsula, while historical scholars usually discuss the Balkans as a region. The term has acquired a stigmatized and pejorative meaning related to the process of Balkanization. The region may alternatively be referred to as Southeast Europe.

Croatia, officially the Republic of Croatia, is a country in Central and Southeast Europe, on the coast of the Adriatic Sea. It borders Slovenia to the northwest, Hungary to the northeast, Serbia to the east, Bosnia and Herzegovina and Montenegro to the southeast, and shares a maritime border with Italy to the west. Its capital and largest city, Zagreb, forms one of the country's primary subdivisions, with twenty counties. Other major urban centers include Split, Rijeka and Osijek. The country spans 56,594 square kilometres (21,851 square miles), and has a population of nearly 3.9 million.

The Croats arrived in modern-day Croatia, then part of Roman Illyria, in the late 6th century. In the 7th century, they organized the territory into two duchies. Croatia was first internationally recognized as independent on 7 June 879 during the reign of Duke Branimir. Tomislav became the first king by 925, elevating Croatia to the status of a kingdom. During the succession crisis after the Trpimirović dynasty ended, Croatia entered a personal union with Hungary in 1102. In 1527, faced with Ottoman conquest, the Croatian Parliament elected Ferdinand I of Austria to the Croatian throne. In October 1918, the State of Slovenes, Croats, and Serbs, independent from the Habsburg Empire, was proclaimed in Zagreb, and in December 1918, it merged into the Kingdom of Yugoslavia. Following the Axis invasion of Yugoslavia in April 1941, most of Croatia was incorporated into a Nazi-installed puppet state, the Independent State of Croatia. A resistance movement led to the creation of the Socialist Republic of Croatia, which after the war became a founding member and constituent of the Socialist Federal Republic of Yugoslavia. On 25 June 1991, Croatia declared independence, and the War of Independence was successfully fought over the next four years.

Yugoslavia (/ˌjuːɡoʊˈslɑːviə/; lit. 'Land of the South Slavs') was a country in Central Europe and the Balkans that existed from 1918 to 2003. 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.

This article lists the heads of state of Yugoslavia from the creation of the Kingdom of Serbs, Croats and Slovenes (Kingdom of Yugoslavia) in 1918 until the breakup of the Socialist Federal Republic of Yugoslavia in 1992.

The Kingdom of Yugoslavia was a hereditary monarchy ruled by the House of Karađorđević from 1918 until World War II. After the war, SFR Yugoslavia was headed first by Ivan Ribar, the President of the Presidency of the National Assembly (the parliamentary speaker), and then by President Josip Broz Tito from 1953 up until his death in 1980. Afterwards, the Presidency of Yugoslavia assumed the role of a collective head of state, with the title of President of the Presidency of Yugoslavia rotating among the representatives of the republics and autonomous provinces that composed the Presidency. However, until 1990 the position of leader of the League of Communists of Yugoslavia was usually the most powerful position, most often coinciding with the President of the Presidency. With the introduction of multi-party system in 1990, individual republics elected their own heads of state, but the country's head of state continued to rotate among appointed representatives of republics and autonomous provinces until the country dissolved two years later.

The Niš Declaration (Serbian: Niška deklaracija, Serbian Cyrillic: Нишка декларација) was a document issued on 7 December 1914, in the midst of World War I, in which the government of the Kingdom of Serbia formally declared its wartime objectives. Published during the Battle of Kolubara as a defensive declaration seeking to attract support from the South Slavs living in Austria-Hungary, it contained a promise to work for the liberation of South Slavs from foreign rule and the establishment of a common South Slavic state after the war. As the Serbian government had withdrawn from Belgrade earlier in the conflict, the declaration was adopted in the temporary Serbian capital of Niš.

The Triple Entente did not accept the objectives set out in the Niš Declaration because they supported the preservation of Austria-Hungary. In subsequent years, Allied support for a separate peace with Austria-Hungary and trialist reform proposals such as the May Declaration of 1917 motivated the Serbian government to cooperate with the Yugoslav Committee. Negotiations between the Serbian government and the Yugoslav Committee led to the Corfu Declaration of 1917, in which the two sides agreed to the creation of a common South Slavic state once the war had ended.

The Corfu Declaration (Serbo-Croatian: Krfska deklaracija, Крфска декларација) was an agreement between the prime minister of Serbia, Nikola Pašić, and the president of the Yugoslav Committee, Ante Trumbić, concluded on the Greek island of Corfu on 20 July 1917. Its purpose was to establish the method of unifying a future common state of the South Slavs living in Serbia, Montenegro and Austria-Hungary after the First World War. Russia's decision to withdraw diplomatic support for Serbia following the February Revolution, as well as the Yugoslav Committee's sidelining by the trialist reform initiatives launched in Austria-Hungary, motivated both sides to attempt to reach an agreement.

Pašić and Trumbić's positions were disparate. Pašić advocated for a centralist government, while Trumbić argued for a federal state, leaving significant powers to federal units and safeguarding national rights. The resulting declaration glossed over the matter of the system of government. As a compromise, it specified only that the common Kingdom of Serbs, Croats and Slovenes would be a constitutional monarchy ruled by the currently reigning Serbian Karađorđević dynasty, deferring most questions to a future Constitutional Assembly. During the discussions, which lasted 35 days, Trumbić had little support for his view from the other members of the Yugoslav Committee, who were preoccupied with the threat posed by Italy, which had been promised territory under the 1915 Treaty of London.
