Ustasa was a Croatian fascist party that controlled the Independent State of Croatia, a puppet state of Nazi Germany, from 1941 to 1945. This organization helped to implement the Holocaust in Croatia. Under leader Ante Pavelic, the Croatian state persecuted its Serb, Jewish, and Roma populations. Thirty thousand Jews and 325.000 to 333.000 Serbs were murdered in the territory of the Independent State of Croatia under the Ustasa government.
