Mandate, issued by Emperor Ferdinand I, King of Germany, for the Archbishopric of Mainz [Present-day Germany]: “Henceforth, no Jew or Jewess in the Archbishopric of Mainz may lend anything to Our subjects and residents without the permission of the Archbishop of Mainz, be it against a collateral of small items, clothes, or any other movable or immovable goods, in any kind of usurious manner; any claims to such debts that were incurred without such permission shall be null and void, and no court shall accept to hear any case in such a matter. Notwithstanding any additional penalties, contraventions of this order shall incur a fine of twenty marks in gold, half of which is payable to Our imperial tax chamber, with the other half payable to the Archbishop of Mainz.”
