“Jewish Dress Code” issued by the Abbasid Caliphate [Abbasid Dynasty; Present-day Saudi Arabia, Iran, Yemen, Oman] [Provisional]: “[… Jews are required to wear] two yellow badges, one on the headgear and one on the neck. Furthermore, each Jew must hang round his neck a piece of lead with the word dhimmi [Jew] on it. He also has to wear a belt round his waist. The women have to wear one red and one black shoe and have [to have] a small bell on their necks or shoes.” [Researcher’s note: The original documents have been lost. However, the decree has been found described in a Genisa* document (*documents found hidden in Jewish synagogues)].
