Marking Jews. Who came up with that? Hmmm....
The practice of wearing special markings in order to distinguish Jews and other non-Muslims (Dhimmis) in Muslim-dominated countries seems to have been introduced by Umayyad Caliph Umar II in early 8th century.The practice was reissued and reinforced by Caliph Al-Mutawakkil (847–61), subsequently remaining in force for centuries.[2][3] A genizah document from 1121 gives the following description of decrees issued in Baghdad:
Two yellow badges [are to be displayed], 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 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 a small bell on their necks or shoes.[4]
