The Zeta Banovina, was a province (banovina) of the Kingdom of Yugoslavia between 1929 and 1941. This province consisted of all of present-day Montenegro as well as adjacent parts of Central Serbia, Croatia, Kosovo and Bosnia and Herzegovina. It was named after the Zeta River which also gave its name to the medieval state of Zeta that roughly corresponds to modern-day Montenegro. The capital of Banovina was Cetinje.
