Syrmia Oblast
Syrmia Oblast ( or ; ) was one of the oblasts of the Kingdom of Serbs, Croats and Slovenes from 1922 to 1929. Its administrative center was Vukovar.

History
The Kingdom of Serbs, Croats and Slovenes was formed in 1918 and was initially divided into counties and districts (this division was inherited from previous state administrations). In 1922, new administrative units known as oblasts (Serbo-Croatian: oblasti / области) were introduced and the whole country was divided into 33 oblasts. Before 1922, territory of Syrmia Oblast was part of the Syrmia County.

In 1929, 33 oblasts were administratively replaced with 9 banovinas and one district, and territory of Syrmia Oblast was divided between the Danube Banovina, the Drina Banovina, and the Belgrade City Administration.

Geography
The Syrmia Oblast included the entire region of Syrmia. It shared borders with the Bačka Oblast in the north, the Belgrade Oblast in the east, the Valjevo Oblast, the Podrinje Oblast and the Tuzla Oblast in the south, the Vrbas Oblast in the south-west, and the Osijek Oblast in the west.

Demographics
