The lagums remained an important part of the local Zemun identity, preserving the spirit of the town and personal memories. For generations of the local boys, descending into the lagums, wandered through them and stayed below as long as possible, which was of a coming of age ritual. Even the name, Zemun, comes from the words zemlja (earth) or zemunica (dug out). Neighbourhoods and suburbs The municipality has only two official settlements: Belgrade (Zemun), which is part of the urban Belgrade city proper (uža teritorija grada; statistically classified as Belgrade-part) and the village of Ugrinovci (which includes the hamlets of Grmovac and Busije). Many of the neighbourhoods developed in the last few decades (Altina, Plavi Horizonti, Kamendin, Grmovac, Busije, etc.).

Germany technically recognised Zemun and surroundings as part of the Independent State of Croatia puppet regime, but Zemun remained under direct German rule. During this time the Sajmište concentration camp was established, where over 20000 Jews, Romani and opponents of the Nazi regime died.
