Yugoslavia
For ten years it was known as the Kingdom of Serbs, Croats, and Slovenes. It began using the name 'Yugoslavia' in 1929. The name 'Yugoslavia' is Serbo-Croatian for 'Land of the Southern Slavs'. The Kingdom was invaded by Axis powers in 1941 and quickly fell during World War II. The Federal Democratic Republic was declared in 1943 with the King's approval, but the monarchy was abolished shortly after.
