how did the nazi policy of anti-semitism evolve in germany?

The Nazi Party rose to power with an anti-Semitic racial ideology. However, the anti-Jewish campaign was not conducted according to a blueprint, rather it evolved. Before the outbreak of the war, political and economic factors, as well as public opinion both inside and outside Germany influenced the evolution of Nazi anti-Jewish laws and measures.
The main purpose of the anti-Jewish policy between 1933 and 1939 according to the racial theory was to isolate German Jewry from German society. These laws sought to uproot and dispossess Jews economically from daily life in Germany and encourage them to leave their homeland. These laws limited and humiliated Jews on a daily basis.
