The persecution of the Jewish population was accompanied by a large-scale anti-Semitic propaganda campaign aimed at the " Aryan " population – first of all at Poles . Using the " gadzinowa " press , cinema or poster , the occupying forces tried to deepen anti-Semitic attitudes and stereotypes , which were already widespread in some parts of Polish society before the war . The German propaganda attempted , among other things , to blame Jews for the outbreak of the war and the occupational shortages , as well as to dehumanize them in the eyes of Polish society , e. g. through accusations of spreading infectious diseases ( e. g. poster " Jews – lice – typhoid typhus " ) . After the beginning of the war with the USSR and the discovery of the Katyn graves , the slogan of " Judeo-Communism " was also intensively used . In many cases , anti-Semitic propaganda has found its way into fertile soil and influenced Poles ' attitudes towards Jews , even after the " final solution " was initiated
