State of Slovenes, Croats and Serbs

The State of Slovenes, Croats and Serbs (Slovene: Država Slovencev, Hrvatov in Srbov; Croatian: Država Slovenaca, Hrvata i Srba; Serbian: Држава Словенаца, Хрвата и Срба) was a country that was created in October 1918, in Southeast Europe. Before that, it's land was a part of Austria-Hungary. When Austria-Hungary lost the World War I, it was broken up. Slovenes, Croats and Serbs are slavic peoples that lived in the south of Austria-Hungary. Their leaders and representatives wanted their people to come together and live in one country. In December 1918, soon after it was created, it joined the Kingdom of Serbia where many Serbs were already independent. This new country became the Kingdom of Serbs, Croats, and Slovenes which changed it's name to Yugoslavia in 1929.
