Zunnar (also spelled "zunar" or "zonar"; Arabic: زنار zunār) was a distinctive belt or girdle, part of the clothing that Dhimmi (e.g. Jews, Christians and Zoroastrians) were required to wear within the Islamic caliphate regions to distinguish them from Muslims.[1] Though not always enforced, the zunnar served, together with a set of other rules, as a covert tool of discrimination.[2][3]
