Edict issued by Friedrich III, Duke of Prussia [Present-day Germany]: “[…] When a Jew lends money to a Christian, a distinction should be made, as to whether the loan period is only a few days or a month, and thus, since a Jew often makes a living from this, the same should be allowed twelve thalers interest out of a principal of one hundred, or at the most four and twenty, in proportion to an annual interest rate; when, however, the loan period is a whole year, no Jew shall take more than twelve per hundred.”
