 The Axis occupation of Yugoslavia in 1941 allowed the Croatian radical right Ustaše to come into power, forming the "Independent State of Croatia" ("Nezavisna Država Hrvatska", NDH), led by Ante Pavelić, who assumed the role of "Poglavnik".Following the pattern of other fascist regimes in Europe, the Ustashi enacted racial laws, formed eight concentration camps targeting minority Serbs, Romas and Jewish populations, as well as Croatian and Bosnian Muslim partisans.The biggest concentration camp was Jasenovac in Croatia.
