With Germany and Italy's support, the Croatian ultra-nationalist Ustaše movement came to power in the newly established puppet state called the Independent State of Croatia (NDH). The Ustaše were notoriously antisemitic, and wasted little time in instituting anti-Jewish legislation and persecuting the Jews under their control. Indeed, NDH Interior Minister Andrija Artuković said in 1941 upon the proclamation of racial laws: ""The Government of NDH shall solve the Jewish question in the same way as the German Government did"". Already in April 1941, the Ustaše and Volksdeutche burned the synagogue and destroyed the Jewish cemetery in Osijek, while the Ustaše mayor of Zagreb, Ivan Werner, ordered the destruction of the main Zagreb synagogue, which was completely razed in 1942The Ustaše set up a number of concentration camps with the most notorious being Jasenovac in which 20,000 Jews were murdered.
