Here are some sample listings:
1320: The “Shepherds’ Crusade.” A Christian chronicler records: “The shepherds laid siege to all the Jews who had come from all sides to take refuge… the Jews defended themselves heroically… but their resistance served no purpose, for the shepherds slaughtered a great number of the besieged Jews by smoke and by fire… The Jews, realizing that they would not escape alive, preferred to kill themselves… They chose one of their number (and) this man put some five hundred of them to death, with their consent. He then descended from the castle tower with the few Jewish children who still remained alive… They killed him by quartering. They spared the children, whom they made Catholics by baptism”
1553: Cardinal Carafa instigates a public burning of copies of the Talmud and other Jewish religious works in a square in Rome
1555-1559: Pope Paul IV restricts Jews to ghettos and decrees that they are to wear distinctive headgear
1566-1572: Pope St. Pius V expels Jews from the Papal States, allowing some to remain in Rome’s ghettos and in Ancona for commercial reasons
1592-1605: Pope Clement VIII includes a ban on all Jewish books in the expanded Index of Forbidden Books
