Constantine was favourable to Christianity. He finalised the end of the Great Persecution of Christians, promoted Christians within the imperial bureaucracy and tried to arbitrate disputes between competing Christian doctrines. He also built important Christian churches: the original Basilica of St Peter's in Rome, the St John Lateran's Basilica (the city of Rome's first Cathedral and the original residence of the Popes), the Church of the Holy Apostles and the Hagia Eirene in Constantinople and Church of the Holy Sepulchre, in Jerusalem. Therefore, Constantine helped Christianity to become an established religion in the Roman Empire and to spread further.
Constantine the Great supported Christianity. He ended the last remnants of the Great (and last) Persecution of the Christians which had started in 303. He promoted Christians to high offices in the imperial administration and arbitrated disputes between various Christian theologies. He built Christian churches, most notably, the original Basilica of St Peter's in Rome, the St John Lateran's Basilica (the city of Rome's first Cathedral and the original residence of the Popes), the Church of the Holy Apostles in Constantinople and Church of the Holy Sepulchre in Jerusalem. Therefore, he created the first steps of Christianity becoming the established religion of the Roman Empire.
With regard to the Roman Empire, he continued the policy his predecessor, Diocletian, had doubled the size of the imperial bureaucracy and made the rule by the emperor an autocratic one.
Constantine's reign as Roman emperor (A.D. 306-337) dramatically changed the direction of Christianity, though in ways far different from those portrayed in The Da Vinci Code. This grew out of his strategy for unifying his empire by creating a “catholic”—meaning universal —church that would blend elements from many religions into one.

Emperor Constantine I and his mother Helena.
As Roman Emporer, Constantine declared Christianity to be the official religion of the Roman Empire. At the time, the Empire was vast, so Christianity spread quickly.
Constantine helped spread Christianity throughout the Roman Empire. He issued the Edict of Milan in 313, which granted religious tolerance to Christians and allowed them to practice their faith openly. Constantine's conversion to Christianity and support of the religion played a significant role in its growth and development.
Christianity
Because Emperor Constantine made it the official religion of the Roman Empire in the East. year 240 ad
Both Islam and Christianity religions were spread through people free choice and will. However, the early spread of Islam was through fighting against the pagans who were attacking Muslims from time to time. While the early wide spread of Christianity was through the convert of the emperor Constantine to Christianity and accordingly persuaded the empire people to convert to Christianity.
Constantine was important to the spread of Christianity because he was considered to be the first Christian emperor. He actually made it legal to be a Christian or to be of the Christian faith.
to me it does not matter when or where it happened however i do have some belif that it started after the death of Christ, which shows me that it has grown and spread since then The answer to the question is: Christianity became declared legal under the rule of the Roman emperor Constantine in 313 A.D. Chrstianity was called Christianity after Christ came and ascended.
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.

I learnt this in worl religions...I can't remember which emperor, but I'm pretty sure it was after Nero...anyway this guy was going to battle with an army and he claimed that god spoke to him and told him to mark their shields with his symbol and they would win, and so they did mark their shields, and they did win, they then returned to Rome and Christianity was made legal and it spread like wildfire...oh I remember his name now Emperor Constantine...so really Christianity didn't convert anybody, an emperor allowed already converted peopel to practice without fear of death and so it spread faster
