convert Gentiles to Judaism. It has also been argued that some people adopted some Jewish practices and belief in the Jewish God without actually converting (called God-fearers). The fate of Jews in Rome and Italy fluctuated, with partial expulsions being carried out under the emperors Tiberius and Claudius. After the successive Jewish revolts of 66 and 132 CE, many Judean Jews were brought to Rome as slaves (the norm in the ancient world was for prisoners of war and inhabitants of defeated cities to be sold as slaves). These revolts caused increasing official hostility from the reign of Vespasian onwards. The most serious measure was the Fiscus Judaicus, which was a tax payable by all Jews in the Roman Empire. The new tax replaced the tithe that had formerly been sent to the Temple in Jerusalem (destroyed by the Romans in 70 CE), and was used instead in the temple of Jupiter Optimus Maximus in Rome. In addition to Rome, there were a significant number of Jewish communities in southern Italy during this period. For example, the regions of Sicily, Calabria, and Apulia had well established Jewish populations. Late antiquity With the promotion of Christianity as a legal religion of the Roman Empire by Constantine in 313 (the Edict of Milan), the position of Jews in Italy and throughout the empire declined rapidly and dramatically. Constantine established oppressive laws for the Jews; but these were in turn abolished by Julian the Apostate, who showed his favor toward the Jews to the extent of permitting them to resume their plan for the reconstruction of the Temple at Jerusalem. This concession was withdrawn under his successor, who, again, was a Christian; and then the oppression grew considerably. Nicene Christianity was adopted as the state church of the Roman Empire in 380, shortly before the fall of the Western Roman Empire. At the time of the foundation of the Ostrogothic rule under Theodoric (493–526), there were flourishing communities of Jews in Rome, Milan, Genoa, Palermo, Messina, Agrigentum, and in Sardinia. The Popes of the period were not seriously opposed to the Jews; and this accounts for the ardor with which the latter took up arms for the Ostrogoths as against the forces of Justinian—particularly at Naples, where the remarkable defense of the city was maintained almost entirely by Jews. After the failure of the various attempts to make Italy a province of the
