Roman and Eastern Roman emperors
Under Christian emperors, Jews were persecuted in the Roman and Eastern Roman Empires, including forbidding Jews from marrying Christians and restricting Jewish ownership of slaves by Emperors Constantine I, Constantius II, and Theodosius I in the 4th century, restricting Jews from holding public office by Emperor Theodosius II in the 5th century, and forced conversions of Jews to Christianity by Emperors Heraclius I, Leo III, Basil I, and Romanos I Lekapenos between the 7th and 10th centuries.

Ambrose of Milan
During the 4th century, Bishop Ambrose of Milan was hateful toward Jews. Ambrose defended a bishop involved in the destruction of a synagogue and expressed that he wanted to have burned down a synagogue with his own hands. He also blamed Jews for the death of Jesus Christ.

Philaster of Brescia
In 388, Bishop Philaster of Brescia encouraged the populace of Rome to set fire to a synagogue.

Ostrogothic Ravenna
After being incited by clergy, a Christian mob burned down synagogues in the Ostrogoth capital city, Ravenna, in 519.

Victor of Palermo
In 598, Bishop Victor of Palermo confiscated synagogues and converted them to churches.

Papacy
The popes of the papacy have made laws restricting Jewish people, which includes Jews being prohibited from holding public office (1078, 1215, and 1442), prohibited from the construction of synagogues (1442 and 1555), prohibited from testifying against Christians (1442), forced to live in ghettos (1555, 1775, 1823, and 1850), forced to wear a Jewish badge and hat (1215, 1218, and 1555), and expelled from the Papal States (1569 and 1593). Pope Benedict VIII (1012-1024) and Pope Paul IV (1555-1559) ordered the execution of a number of Jews.

King Frederick II of Sicily in 1310 prohibited Jewish doctors from attending to Christian patients in Sicily and in 1312 ordered Jews to live outside the city wall of Palermo in a ghetto.

Blood libels
Jews were forcibly converted and killed in Trani in the 1290s after a blood libel, which falsely accuses Jews of having killed a Christian child for a ritual. In 1475, Jews were falsely accused in a blood libel for the death of Simon of Trent and over a dozen Jews were killed.
