During the 1920s and 1930s Europe saw the outbreak of an aggressive and antisemitic nationalism that made racial and social claims and which saw the Jews as an inferior and dangerous race. It sought to limit Jewish economic activity and distance Jews from public life in their countries. With Adolf Hitler’s rise to power in Germany this racial antisemitism became the official ideology and policy of the German regime. In 1938 an organized campaign took place that included destroying synagogues, mass arrests, destruction and looting of Jewish-owned businesses, and official registration of Jewish property in preparation for eventual confiscation. In addition to Jews, other groups who were deemed enemies of the Reich, such as the Roma and Sinti, homosexuals and the mentally ill, were also persecuted.
