Mandate issued by Prince Elector John Frederick I [Germany] [Unconfirmed]
Commentary from other sources:
1) “Since 1432 Jews had been forbidden to take up permanent residence in Electoral Saxony. It is unclear why Elector John Frederick issued a mandate at the beginning of August 1536 that prohibited them from staying there, engaging in business, or passing through…He appears to have approved the mandate because of the Jews’ unwilling to repent and because of their usury.”

2) “By 1537, [in 1536] a disappointed [Martin] Luther became convinced that most Jews had no intention of converting to Christianity. If conversion was not a possibility, Luther believed there was no reason to tolerate the Jews. He therefore persuaded one of his strongest supporters–the prince of Saxony–to expel Jews from his territory. They could no longer live in, engage in business in, or even pass through Saxony.”
