Kingdom of Serbia
Origins
Prince Milan Obrenović of the Principality of Serbia, independent since 1878, proclaimed himself king in 1882 with the support of Austria-Hungary. His reign brought defeat by Bulgaria at Slivnitsa in 1885 and domestic unrest, and he abdicated in 1889 in favour of his son Alexander.
Rule and society
The unpopular Alexander Obrenović was murdered with his queen by army officers in the May Coup of 1903, and Peter I Karađorđević became king. Under the 1903 constitution and Nikola Pašić's Radical Party, Serbia became a parliamentary state, freed itself from Austrian economic control after the Pig War of 1906, and in the Balkan Wars of 1912 to 1913 gained Kosovo and Vardar Macedonia.
Decline and legacy
After the Sarajevo assassination, Austria-Hungary attacked Serbia in 1914. Overrun in 1915, its army retreated through Albania to Corfu and returned via the Salonika front in 1918. On 1 December 1918 Serbia joined the Kingdom of Yugoslavia, then called the Kingdom of Serbs, Croats and Slovenes.
