Hitler's takeover of power in January 1933 created a new and dangerous situation for German Jewry. Nazi policy developed gradually, but before the spring of 1933 was well advanced there could be little doubt that serious injury was intended toward the Jewish community. The “wildcat” anti-Semitic actions of undisciplined SA men were followed by the national boycott of Jewish businesses conducted on April 1. Legislative and administrative measures, preceded and accompanied by “unofficial” and “illegal” actions tending in the same direction, began the process that drove Jews from public employment, from medicine, law, and teaching, from cultural, political, and journalistic pursuits, and that severely hampered their economic activity in any form. Long before any sane observer could have glimpsed the outlines of the “final solution,” the leaders of the German Jewish community were faced with a situation demanding the utmost of their political and organizational talents. As a leading Jewish participant put it, the situation provided a classic case of Toynbee's “challenge” and “response.” To one German Jewish leader, Georg Kareski, it was a great and positive political opportunity.
