Writ of King Rupert I [Present-day Germany]: “King Rupert grants the city of Nördlingen a Freibrief (letter of freedom)* […] and permits them to keep Jews (settled there) for another 10 years, stipulated that half of the revenues collected from them as well as the golden Opferfennig** from each Jew above the age of 12 [is submitted to him and his chamber …]” [Researcher’s note: *A Freibrief was a letter which granted a city or a person a number of privileges, including often to function semi-autonomously. **The Sacrifice-Penny (‘Opferpfennig’) was a special tax placed on Jews.]
