Before 2nd world war jews occupied all business and wealth in germany but messacare of nuremberg was not good and was injustice according to human rights

Nazi takeover of 1933, which resulted in Adolph Hitler (1889-1945), a virulent anti-Semite, becoming chancellor, was a stunning blow to German Jews. In 1935, the Nuremberg Laws were adopted; these laws officially defined Judaism in terms of race, and withdrew the citizenship of all Jews. The situation escalated in 1938 when Austria was annexed by Germany. The atrocities perpetrated there against Jews soon became common in Germany proper as well. On November 9, 1938, Kristallnacht, Jewish businesses and synagogues were razed, and Jews were hurt and killed in rioting.

The government persecution led to an increased solidarity among German Jewry. Communities banded together to promote immigration, and to provide many of the services that had been stripped away by the government. After the war began, these communal organizations were transformed into the Reichsvereinigung der Juden in Deutschland ("Reich Union of Jews in Germany"), headed by Leo Baeck.
