[Possible/Probable] “Wormser Privilege” Issued by the Holy Roman Emperor Heinrich IV [Present-day Germany / Holy Roman Empire] 

Commentary from other sources:
1) “During the Wormser Privilege, Jews are established as imperial “chamber servants” of the Holy Roman Empire in a collection of legal standards which set a groundbreaking precedence that had a positive as well as a negative impact on the Jews and their relationship to Christians for centuries to come.”
