"United Serbia" refers to the concept of a unified Serbian state that encompasses all territories historically inhabited by Serbs. This idea has been a significant aspect of Serbian nationalism, particularly during the 19th and 20th centuries. It aims to bring together regions such as Kosovo, Vojvodina, and parts of Bosnia and Herzegovina where Serbian communities reside. The notion of United Serbia has been a source of political tension in the Balkans, especially during the breakup of Yugoslavia in the 1990s. Various political movements and parties have advocated for this idea, leading to conflicts and discussions about national identity, sovereignty, and territorial integrity in the region.
