The Jasenovac camp complex at the nowadays Croatia-Republika Srpska border, a string of five camps on the bank of the Sava River (Brickworks, the largest perimeter, Stara Gradiska, work farms and the Ustica Roma camp) functioned between August 1941 and February 1945 under the authorities of the so-called Independent State of Croatia. After seizing power, the Ustasa authorities, of nationalist, fascist and separatist intent, used the complex to isolate and murder approximately 48,000 Serbs, 16,000 Roma and 13,000 Jews, as well as Croatian political and religious opponents of the regime. Although figures are still disputed, having fluctuated both in the historiography of the Socialist Federal Republic of Yugoslavia and after the recent Yugoslav wars, it is estimated that the Ustasa regime murdered between 80,000 and 100,000 people through forced labour and murder. In the contemporary configuration, the memorial site and its communities of victims have been amply speculated, leading to successive attempts to revise the history of Jasenovac, especially since the site is currently divided by the 1995 Croatian -Republika Srpska border.The former complex area rests today on the Croation side while the execution area of Donja Gradina belongs to the Bosnian territory.
