Act issued by King Sigismund II Augustus of Poland & Grand Duke of Lithuania [Present-day Lithuania / Poland] [Provisional]: “The Jews shall not wear costly clothing, nor gold chains, nor shall their wives wear gold or silver ornaments. The Jews shall not have silver mountings on their sabers and daggers; they shall be distinguished by characteristic clothes; they shall wear yellow caps, and their wives kerchiefs of yellow linen, in order that all may be enabled to distinguish Jews from Christians.”
