evidence: The official website of Liberland declares that the nation could be created due to the territorial dispute between Serbia and Croatia. Since the Yugoslav War, some territories on the Serbo-Croatian border have been in dispute, such as Vukovar Island and Šarengrad Island. Despite this, some other territories were not claimed by either side. Liberland was proclaimed on the largest plot of land in these unclaimed territories, which is known as Gornja Siga.
