After World War I there was a controversy over the Balkan region. The countries that supported the allies wanted more land and to unify the region. Yugoslavia was the name that came up and it was made up of Serbia and southern parts of Austria-Hungary. Italy did not want Yugoslavia to gain lands or power but after a several months The U.S., France and Britain finally recognized Yugoslavia. Yugoslavia had many divisions in language, religion, culture and race. There were Orthodox, Catholics and Muslims as well as Serbs, Croats, Slovenes, Bosnians and Montegrins. Some of these people even fought against each other in the war that had just taken place.
             The Serbian Prime Minister Nikolas Pasic and the Croatian exile Ante Trumbic came up with the Corfu Deceleration. The agreement was a triumph for the Trumbic who had worked to convince Pasic's Serbian government to sponsor the notion of a union of the Croats, Slovenes and Slavs, an idea that was regarded with great mistrust by Pasic who remained intent upon the simple expansion of Serbia via territorial gains from a beaten Austrian-Hungarian empire. Pasic though said that the Corfu Deceleration was only written for propaganda and that any new state would be controlled by Serbia.
             Before the Peace Conference the South Slavs had already taken matters into their own hands and in October 1918 a council of Serbs, Croats and Slovenes declared their independence from Austria-Hungary. Many Croats wanted their own independent Croatia. On December 1st 1918 Prince Alexander of Serbia proclaimed the Kingdom of Serbs, Croats, and Slovenes. There was still a lot of debate as Serbia wanted the area to be Serbia and the Croats and Slovenes wanted a new country; Yugoslavia. The Serbs controlled the country even though they had less than half the total population. The Serbian army was the national army and the government was made up of mostly Serbs.
