In 1931,
Mitrovica and
Šid districts were transferred from
Drina Banovina to Danube Banovina. In 1939, when the new
Banovina of Croatia was formed,
Šid and
Ilok districts were transferred from the Danube Banovina to that of Croatia. In 1941, the
World War II Axis powers occupied the Danube Banovina. Bačka and Baranja regions were attached to
Hungary, while Syrmia was attached to the
Independent State of Croatia. The remainder of the former Danube Banovina (including Banat, Šumadija, and Braničevo) were part of the
Territory of the Military Commander in Serbia. However, Banat had autonomy as a region ruled by its
ethnic German minority. In 1945, the region was restored as a province of Serbia within a
federal Socialist 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. ==Cities==
