Jasenovac concentration camp (Croatian, Serbian: Logor Jasenovac; Cyrillic script: Логор Јасеновац) was the largest concentration and extermination camp in Independent State of Croatia during World War II. It was established by the Ustaše (Ustasha) regime in August 1941. It was dismantled in April 1945. Unlike other concentration and extermination camps, in Jasenovac the largest number of victims were ethnic Serbs, whom Ante Pavelić considered the main racial enemy of the NDH. The camp also held Jews, Roma, and large numbers of Croatian resistance members, most notably Partisans. Jasenovac was a complex of five subcamps and three smaller camps spread over 240 square kilometers (93 square miles) on the banks of the Sava river. The largest camp was at Jasenovac, about 100 km (62 miles) southeast of Zagreb. The complex also included large grounds at Donja Gradina directly across the Sava river, a camp for children in Sisak to the northwest, and a women's camp in Stara Gradiška to the southeast. The Jasenovac Memorial Area maintains a list of the names of 69,842 Jasenovac victims, including: 39,580 Serbs, 14,599 Roma, 10,700 Jews, 3,462 Croats, as well as people of some other ethnicities. The Belgrade Museum of the Holocaust keeps a list of the names of 80,022 victims (mostly from Jasenovac), including: around 52,000 Serbs, 16,000 Jews, 12,000 Croats and nearly 10,000 Roma.
