The 
Kingdom of Yugoslaviaball, previously called the Kingdom of Serbs, Croats and Slovenesball, is an historical Slavic countryball composed by 
Serbia, 
Croatiaball, 
Bosniaball, 
Montenegroball, 
Sloveniaball and 
Macedoniaball. Relatively big, it occupied most of Balkan clay with his neighbors 
Romaniaball, 
Bulgariaball, 
Albaniaball and 
Greeceball. He was partially occupied by 
Fascist Italyball and 
Nazi Germanyball, both of whom supported and recognized 
Croatian Rebels inside his clay.
History:
The Kingdom of Yugoslaviaball was born when 
Kingdom of Serbiaball anschlussed the 
State of Slovenes, Croats and Serbsball, as nobody wanted to recognise it as a real state (even though EVERYONE promised to do so) and the 
Kingdom of Montenegroball. The country was known as the Kingdom of Serbs, Croats and Slovenesball, before it changed its name to Kingdom of Yugoslaviaball, by royal decree. He had several internal problems with his two biggest minorities, the Banovina of Croatiaball and the Slovenian Drava Banovinaball.
Like his "brother" ( 
Yugoslaviaball) he had multi personality dissorder, and wanted to get medical help to cure it, but before he could have succeeded, he was attacked by Nazi Germanyball, the Kingdom of Italyball, the 
Kingdom of Hungaryball (1920-46), and by the Kingdom of Bulgariaball.
While he was under 
German and Italian 
occupation, his clay was divided, creating new axis states. These included Independent State of Croatiaball and a small rump 
Serbiaball while the rest of his clay was partitioned between the two axis powers.
Effective 
resistance movements sought to establish an independent Yugoslaia free from Fascist occupation. The communist Yugoslav partisans managed to gain allied support, leading to the death of a Royal Yugoslavia and the establishment of his cousin.
