A rare anti-Semitic work, published in January 1941, on the eve of WWII in Yugoslavia, was written by a lawyer, author, publisher and a mayor of Slavonski Brod Radovan Golubić, who was notorious for his hate towards the Jews.
The book discusses the possibility of the “Jewish danger” in Croatia and the author’s own experiences with the Jewish organizations. In the past Golubić was sued by a Jewish community in Croatia for hate speech. The book includes the correspondence between the parties.
Only a few months later, upon the proclamation of the Independent State of Croatia during WWII, a large percentage of the Jewish population was sent to prison and concentrations camps with only small chances to survive until the end of the war.
