According to the 1931 Constitution of the Kingdom of Yugoslavia,
"The Danube Banovina is bounded on the south-west by the boundaries ... of the Sava and Drina Banovinas, on the north and north-east by the State frontiers with Hungary and Romania, up to the point where the latter frontier meets the Danube. The boundary then follows the course of the Danube up to the eastern boundary of the district of Ram and then turns along the south-eastern boundary of the Požarevac district. It then follows the eastern boundaries of the districts of Morava, Lepenica, Kragujevac, and Gruža, as far as the Dulenski Crni Vrh (hill 919), turning towards the Gledic Mountains and thence over the Krečane (hill 760) and Brzak (hill 822) up to the boundary of the Drina Banovina on Mount Kotlenik, near Crni Vrh (hill 768)."
In 1945 the region was restored as a province of Serbia within a federalSocialist Yugoslavia. The province was officially renamed as Vojvodina, its historical name, with the capital at the city of Novi Sad. The new province consisted of Syrmia, Banat and Bačka regions. Baranja was included in the People's Republic of Croatia, while Šumadija and Braničevo were included in Serbia Proper.
