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.
Assassination of Archduke Franz Ferdinand The assassination of Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, and his wife Sophie, Duchess of Hohenberg, occurred on 28 June 1914 in Sarajevo when they were mortally wounded by Gavrilo Princip. Princip was one of a group of six assassins (five Serbs and one Bosniak) coordinated by Danilo Ilić, a Bosnian Serb and a member of the Black Hand secret society. The political objective of the assassination was to break off Austria-Hungary's South Slav provinces so they could be combined into a Yugoslavia. The assassins' motives were consistent with the movement that later became known as Young Bosnia. The assassination led directly to the First World War when Austria-Hungary subsequently issued an ultimatum to the Kingdom of Serbia, which was partially rejected. Austria-Hungary then declared war, triggering actions leading to war between most European states.
