Abraham ben Moses Jaffe of Bohemia (Hebrew: אברהם בן משה יפה מבוהמיה; d. 1533)[1][2] also known by his Latin name "'Abraham Judaeus Bohemus" was a very prominent 16th-century Bohemian Jewish banker, tax collector, money lender and Court Jew who later moved to Poland and served as the Prefect of the Council of Four Lands from 1514 to 1518.
[3][better source needed] Early in his carrier, Abraham amassed a great fortune, which he later lent out to King Vladislaus II of Bohemia and Holy Roman Emperor Maximilian I.
It was also around this time that Abraham became involved in commerce, holding a trading post in Lwów, where he owned a house in the Jewish quarter, given to him by the king.
The king ordered all the Jews of Poland, and especially the rabbis, to respect the liberties and privileges granted to Abraham, and not to encroach upon them by excommunication or in any other such way.
The king also dismissed all accusations against Abraham, freed him from taxes paid by all other Jews, and allowed him freedom of commerce and banking in all Poland.
