The Kingdom of Yugoslavia ( / Краљевина Југославија; ) was a state in Southeast and Central Europe that existed from 1918 until 1941. From 1918 to 1929, it was officially called the Kingdom of Serbs, Croats and Slovenes ( / Краљевина Срба, Хрвата и Словенаца; ), but the term "Yugoslavia" (literally "Land of South Slavs") was its colloquial name due to its origins. The official name of the state was changed to "Kingdom of Yugoslavia" by King Alexander I on 3 October 1929.
