The official name of the province was Banat, Bačka and Baranya, but it was also unofficially known as Vojvodina.
History
Following the collapse of Austria-Hungary in October 1918, the regions of Banat, Bačka and Baranya came under control of the Serbian army, in November. They entered Novi Sad on 9 November and dismantled the Hungarian-supported Banat Republic on 15 November. The local ethnic Serb population from these regions had already formed its own administration under the supreme authority of Serb National Board in Novi Sad.
The Great People's Assembly decided to join Banat, Bačka and Baranya to Serbia, and formed a new local administration (government) in these regions known as the People's Administration for Banat, Bačka and Baranya (Serbo-Croatian: Narodna uprava za Banat, Bačku i Baranju / Народна управа за Банат, Бачку и Барању). The president of the People's Administration was Jovan Lalošević. The People's Council was formed as the legislative body of the province.
Although the government in Belgrade accepted the decision that Banat, Bačka and Baranya had joined Serbia, it did not recognize the People's Administration. The People's Administration for Banat, Bačka and Baranya was active until March 11, 1919, when it held its last session.
Before the peace conference defined the exact borders of the Kingdom of Serbs, Croats and Slovenes, the People's Administration for Banat, Bačka and Baranya also administered parts of Banat, Bačka and Baranya that today belong to Romania and Hungary.
After the Paris peace conference, the Banat, Bačka and Baranya province remained in place until the Vidovdan Constitution of 1921 which established the Kingdom of Serbs, Croats, and Slovenes as a unitary state and replaced in 1922 the 8 Pokrajinas (provinces) by 33 new administrative oblasts (counties) ruled from the center.
Population
The population of Banat, Bačka and Baranya (within the borders defined by the peace conference) was 1,365,596, including 29.1% Serbs, 27.71% Hungarians, 23.10% Germans, and others[1][failed verification – see discussion][2] (such as Romanians). Serbs and Croats together comprised 36.80% of population of the region.[3]
