In the Independent State of Croatia (NDH), the Nazi regime demanded that its rulers, the Ustaše, adopt antisemitic racial policies, persecute Jews and set up several concentration camps. NDH leader Ante Pavelić and the Ustaše accepted Nazi demands. By the end of April 1941 the Ustaše required all Jews to wear insignia, typically a yellow Star of David and started confiscating Jewish property in October 1941. During the same time as their persecution of Serbs and Roma, the Ustaše took part in the Holocaust, and killed the majority of the country's Jews; the United States Holocaust Memorial Museum estimates that 30,148 Jews were murdered. According to Jozo Tomasevich, the Jewish community in Zagreb was the only one to survive out of 115 Jewish religious communities in Yugoslavia in 1939–1940.
