 Once a suburb of Belgrade, separated from it by the vast marshlands on the Sava's left bank, Bežanija today forms one completely urbanized area with Belgrade thanks to the rapid development of Novi Beograd after World War II.Today, Bežanija extends to the northeast into Bežanijska kosa and the west into Ledine.After the World War II ended, Belgrade was divided into raions and Bežanija was part of the Raion X.
