Roman Empire

Who spread Christianity throughout the Roman Empire?


Wiki User

More than anyone before him, Emperor Constantine spread Christianity throughout the Roman Empire. True, Christianity was already well established, especially in the Greek-speaking east, long before the fourth century, but Constantine gave the religion state patronage, offered career preferment to those who claimed to be Christians, and began the long persecution of the pagan temples. From this time, and with this impetus, Christianity spread quickly in the Roman Empire.
