several other religions and imported mystery cults remained represented within its ever-expanding boundaries during the roman republic and empire periods, including judaism, whose presence in the city dates back from the roman republic and was sometimes forcibly confined to the roman ghetto, as well as mithraism which was the official religion of the roman empire for about two centuries, until being superseded by christianity, following the death of emperor constantine in the 4th century. christianity was made the official religion of the roman empire in 380 by emperor theodosius i, allowing it to spread further and eventually wholly replace mithraism in the roman empire.
