What actions taken by the Nazis prevented Jewish people from leaving Germany?

The Nazis said that the Jews had a plan for world domination and strongly criticized economic liberalism and financial capitalism, as they claimed that both were dominated by the Jews. One of the clear examples of this idea (situated at the time of the conspiracy theories used to accuse the Jews) was a book of Russian origin and an unknown author that was a sales success in Germany: "The protocols of the wise men of Zion".

When the Nazis came to power in Germany in 1933, the process of exclusion and violence against the Jews started progressively. Nazi speech, coupled with indoctrination carried out in German society, made Jews scapegoats and victims of intense persecution, not only by the government, but also by civilians.

One of the first actions taken by the Nazis against the Jews was a law, passed on April 7, 1933, called Berufsbeamtengesetz, translated into Portuguese as the Law for Restoration of Professional Public Service. This law definitively forbade Jews from taking public office. Other such laws have been passed for other trades, such as doctors and lawyers. In addition to the laws, Jews were the target of attacks by Nazi assault troops (SA) and their stores were boycotted nationwide.

As time passed, new actions against Jews were being organized in Germany. This persecution forced thousands of Jews to flee the country, but many others failed, as no country was willing to receive them. In the 1930s, two measures taken by Hitler symbolized the reinforcement of anti-Semitism in Germany: the Nuremberg Laws and the Night of the Crystals.
