Once in power Adolf Hitler began to openly express anti-Semitic ideas. Based on his readings of how blacks were denied civil rights in the southern states in America, Hitler attempted to make life so unpleasant for Jews in Germany that they would emigrate. The campaign started on 1st April, 1933, when a one-day boycott of Jewish-owned shops took place. Members of the Sturm Abteilung (SA) picketed the shops to ensure the boycott was successful.
The hostility of towards Jews increased in Germany. This was reflected in the decision by many shops and restaurants not to serve the Jewish population. Placards saying "Jews not admitted" and "Jews enter this place at their own risk" began to appear all over Germany. In some parts of the country Jews were banned from public parks, swimming-pools and public transport.
Germans were also encouraged not to use Jewish doctors and lawyers. Jewish civil servants, teachers and those employed by the mass media were sacked. Members of the SA put pressure on people not to buy goods produced by Jewish companies. For example, the Ullstein Press, the largest publisher of newspapers, books and magazines in Germany, was forced to sell the company to the NSDAP in 1934 after the actions of the SA had made it impossible for them to make a profit.
Many Jewish people who could no longer earn a living left the country. The number of Jews emigrating increased after the passing of the Nuremberg Laws on Citizenship and Race in 1935. Under this new law Jews could no longer be citizens of Germany. It was also made illegal for Jews to marry Aryans.
