In 1933, Hitler rose to power and became the Chancellor of Germany. In the same year, Jews were prohibited from working for the German government and joining sports clubs. This was the beginning of the discrimination against Jews leading up to the Holocaust.
In 1935, Jews were discriminated against by the German government when they lost their rights as German citizens. Their passports were restricted and they were forbidden from marrying non-jewish citizens to "protect german blood". This was classification, as people were taught to see Jews as a different race to Aryan Germans.
In 1938, Jewish children were prohibited from attending the same school as non-Jewish children, and those who were already in schools with non-jews were humiliated in front of their classmates before being expelled.
In the same year, Jewish doctors were also forbidden from treating non-jewish patients. This was polarisation, the Jewish doctors could only treat Jewish patients, and non-german doctors would only treat non-jewish patients.
In 1939, Landlords were allowed to evict Jewish residents at any given time. Jews were also mandated to be home by 9 pm during the winter, and 8 pm during the summer. This was discrimination, as the landlords had the right to evict Jewish residents purely because they are Jewish.
In 1941, it was mandatory for Jewish people above the age of 6 to wear a yellow star to identify that they are Jewish, this was symbolisation, to encourage citizens to go against Jews. Jewish people were no longer allowed to leave Germany.
