On September 1, 1941, the Reich Minister of the Interior decreed that Jews over the age of six in the Greater German Reich were required to wear a yellow Star of David on their outer clothing in public at all times.
While ghettos were generally not established in Germany, strict residence regulations forced Jews to live in designated areas of German cities, concentrating them in “Jewish houses”
In Christian countries, dress codes were imposed on Jewish and other non-Christian residents.
The badge was an obvious, visual, step back to the Middle Ages, a time before Emancipation.
If a Jew forgot to wear their badge they could be fined or imprisoned, but often, it meant beatings or death. Jews came up with ways to remind themselves not to go out without their badge.
REMEMBER THE BADGE
Wearing the badge meant that they were targets for attacks and that they could be grabbed for forced labor.
