The Grand National Assembly not only declared the unification of Banat, Bačka and Baranja with the Kingdom of Serbia, but also made a decision on the formation of a provincial administration (government and assembly) in these regions. The provincial government was officially named People's Administration for Banat, Bačka and Baranja, and Jovan Lalošević was elected its president, while the provincial assembly was officially called the "Great People's Council", whose president was elected Slavko Miletić.
