Yugoslavia (Serbo-Croatian, Macedonian, Slovene: Jugoslavija, Југославија), was a country in Southeast Europe during most of the 20th century. It came into existence after World War I in 1918[ii] under the name of Kingdom of Serbs, Croats and Slovenes, by the merger of the provisional State of Slovenes, Croats and Serbs (itself formed from territories of the former Austro-Hungarian Empire) with the formerly independent Kingdom of Serbia and Kingdom of Montenegro. Serbian royal House of Karađorđević became the Yugoslav royal dynasty. Yugoslavia gained international recognition on 13 July 1922 at the Conference of Ambassadors in Paris. The country was named after South Slavic peoples as their first union ever, after centuries-long rules of the Ottoman Empire and Austria-Hungary on these territories.
