History of Serbia The Serbian realms disappeared by the mid-16th century, torn by domestic feuds and overcome by Ottoman conquest. The success of the Serbian revolution against Ottoman rule in 1817 marked the birth of the Principality of Serbia, which achieved de facto independence in 1867 and finally gained recognition by the Great Powers in the Berlin Congress of 1878. As a victor in the Balkan Wars of 1912-1913, Serbia regained Vardar Macedonia, Kosovo and Raška (Old Serbia). In late 1918 the region of Vojvodina proclaimed its secession from Austria-Hungary to unite with the pan-Slavic State of Slovenes, Croats and Serbs; the Kingdom of Serbia joined the union on 1 December 1918, and the country was named the Kingdom of Serbs, Croats, and Slovenes.

World War I On 28 June 1914, Gavrilo Princip, a Bosnian Serb supporter of Yugoslav nationalism, assassinated the Austro-Hungarian heir Archduke Franz Ferdinand while he was visiting Sarajevo. The instability caused by competing Russian and Austro-Hungarian objectives in the Balkans meant this led to a diplomatic crisis, which ended with Austria-Hungary issuing an ultimatum to Serbia. [12][13] Interlocking alliances meant the crisis ultimately involved all the major European powers as well as their respective colonial empires and the conflict rapidly spread across the globe.
American entry into World War I On December 7, 1917, the U.S. declared war on Austria-Hungary.[5][6]
Breakup of Yugoslavia After the Allied victory in World War II, Yugoslavia was set up as a federation of six republics, with borders drawn along ethnic and historical lines: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia and Slovenia. In addition, two autonomous provinces were established within Serbia: Vojvodina and Kosovo. Each of the republics had its own branch of the League of Communists of Yugoslavia party and a ruling elite, and any tensions were solved on the federal level. The Yugoslav model of state organization, as well as a "middle way" between planned and liberal economy, had been a relative success, and the country experienced a period of strong economic growth and relative political stability up to the 1980s, under the rule of president-for-life Josip Broz Tito. After his death in 1980, the weakened system of federal government was left unable to cope with rising economic and political challenges.
Triple Entente Historians continue to debate the importance of the alliance system as one of the causes of World War I. At the start of World War I in 1914, all three Triple Entente members entered it as Allies against the Central Powers: Germany and Austria-Hungary.[1]
