This province consisted of all of present-day Montenegro as well as adjacent parts of Central Serbia, Croatia, Kosovo and Bosnia and Herzegovina.

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.

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.

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