How long did the persecution of Christians go on in the Roman Empire?
Any persecution of the Christians ended early in the fourth century, when Christianity received state patronage under Emperor Constantine. Then, later in the fouth century, Christianity became the official religion of Rome and was in a position to persecute pagans and Mithraists. It seems that persecution does not choose its victims – whichever religion is more powerful at the time persecutes the less powerful.
