The Nazi regime begins implementing discriminatory laws against Jewish people in Germany, including boycotts of Jewish businesses, dismissal of Jewish civil servants, and restrictions on Jewish students in schools and universities. These measures prompt Otto Frank to consider moving his family out of Germany.

The Nuremberg Laws are enacted in Germany, stripping Jewish people of their German citizenship and prohibiting marriage and sexual relations between Jews and non-Jews. These laws further marginalize and dehumanize Jewish people.

Germany invades and occupies the Netherlands. The Nazi regime immediately begins implementing anti-Jewish measures, including requiring Jewish people to register with the authorities and restricting their access to public spaces.

Jewish people in the Netherlands are increasingly segregated from the rest of society. They are banned from owning businesses, attending non-Jewish schools, using public transportation, and visiting parks, libraries, and theaters. Jewish people are required to wear a yellow Star of David to identify themselves publicly.

The Nazi regime begins deporting Jewish people from the Netherlands to concentration camps in Eastern Europe. The threat of deportation becomes a constant source of fear and anxiety for Jewish families, including the Franks.

Margot Frank receives a notice ordering her to report for deportation to a labor camp. This event serves as the immediate trigger for the Frank family's decision to go into hiding the following day.
