The collapse of Austria-Hungary in the final days of World War I left its constituent regions in political uncertainty. Serbs, Bunjevci, and other South Slavic peoples in Banat, Bačka, and Baranya sought to determine their own political future as the empire disintegrated in late 1918.
On 25 November 1918, the Great People's Assembly of Serbs, Bunjevci and other Slavs convened in Novi Sad. The assembly, representing communities from Banat, Bačka, and Baranya, passed a resolution declaring those regions' secession from the collapsed Austria-Hungary and their unification with the Kingdom of Serbia.
The formal unification of Banat, Bačka, and Baranya with the Kingdom of Serbia reshaped the territorial composition of the post-war Balkans. This decision contributed to the broader process of South Slavic unification that culminated in the formation of the Kingdom of Serbs, Croats and Slovenes.
