Zeta Banovina

The Zeta Banovina or Zeta Banate (Serbian, Bosnian, Montenegrin and Croatian: Зетска бановина/Zetska banovina) was a province (banovina) of the Kingdom of Yugoslavia between 1929 and 1941. This province consisted of all of the present-day Montenegro as well as adjacent parts of Central Serbia, Kosovo, Croatia, and Bosnia and Herzegovina. It was named for the Zeta River which also gave its name to the Medieval state of Zeta that roughly corresponded to modern Montenegro. The capital city of the Zeta Banovina was Cetinje.

Borders
According to the 1931 Constitution of the Kingdom of Yugoslavia,
 * ''The Zeta Banovina is bounded on the north by the southern boundaries of the Littoral and Drina Banovinas ... as far as the intersection of the boundaries of the three districts of Dragačevo, Žiča and Studenica. From this point and as far as the national frontier with Albania, the boundary of this Banovina follows the eastern boundaries of the districts of Studenica, Deževa, Mitrovica, Drenica and Drin, including all these districts. Then the boundary coincides, up to the Adriatic Sea, with the Yugoslav-Albanian State frontier.

History
In 1939, ethnic Croatian areas of the Zeta Banovina from the Bay of Kotor to Pelješac including Dubrovnik were merged with a new Banovina of Croatia.

In 1941, the World War II Axis Powers occupied the remaining area of the Zeta Banovina. A small area around the Gulf of Kotor was annexed by Fascist Italy while much of the rest was joined with Italian-occupied Montenegro and Albania. Eastern areas were made part of German-occupied Serbia and western areas part of Independent State of Croatia.

Following World War II, the region was divided between Montenegro, Bosnia and Herzegovina, Serbia, and Croatia within a federal Socialist Yugoslavia.

Demographics
According to the 1931 census, the Zeta Banovina had a population of 925,516 and an area of 30,741 km².
