The Emperor Constantine adopted Christianity as the official religion of the Roman Empire, thereby converting it from a small, persecuted minority religion to a powerful, expanding religion. Constantine did not adopt Christianity as the official religion of the Roman Empire. That was done 43 years after his death by the Edict of Thessalonica issued by co-emperors Gratian, Theodosius I and Valentinian II in 380. In Constantine's days Christianity had already become the religion of the masses in the Roman Empire and was already a majority religion. Constantine brought about the final termination of the Great Persecution of Christians (which stared in 303) which was decreed in the Edict of Toleration by (emperor) Galerius and which had been reiterated in the Edict of Milan signed in 313 by himself and his co-emperor Licinius. Constantine supported Christianity and helped it to flourish. 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. However, Constantine also patronised Roman paganism. The triumphal arch he built had images of the goddess Victoria and had no Christian symbols. Sacrifices to Apollo, Diana and Hercules were held when the arch was inaugurated. When he was 49 he established the first day of the week as "the venerable day of the sun" and called it Sunday. He ordered that Christians and non-Christians should observe a sun-worship (established as an official cult by Emperor Aurelia) on on that day. The Chi-Rho (a Christian symbol) appeared or the name of Christ appeared on one side of his coins, but on the other side there was the symbol of Sol Invictus (the sun god) or Mars Conversator. At the dedication of its new capital, Constantinople (in 337) he held the sun-rayed diadem of Apollo and no Christian symbols were used. Constantine also retained the title of pontifex maximus (the head of the Roman pagan religion) until his death. Constantine also moved the capital of the eastern part of the Roman Empire from Nicomedia (in northwestern Turkey) to the nearby Byzantium (originally a Greek city), redeveloped it and renamed it Constantinople (city of Constantine). He resolved the problem of hyperinflation which had been plaguing the empire for a long time.
Constantine, in a vision or drean, saw a cross in the sky! Thinking it to be a sign of victory, he ordered all his soldiers to have crosses painted on their shields. Afterwards, when the battle was won, Constantine made it 'allowable' for Christians to follow their religion of Rome.
It spread through strong and passionate evangelization. Truly these people were ready to die for Jesus and that send a very powerful message. The Romans didn't change until Constantine came along.
Apart from laws which favoured the Christians, Constantine mostly retained the reforms introduced by his predecessor, Diocletian.

He helped to change the empires religious beliefs to Christianity.
The Edict of Milan marked a dramatic change in the way Christians were treated in the Roman Empire. They would now be tolerated instead of persecuted. They would be compensated for property that had been seized.

The poor began to convert (in hopes of a better life after death), people in other classes tired of war, and feared for the empire, and desired the trust, love, and bravery that they believed Christianity would offer, Christians began to better accept the Empire, and Constantine legalized the religion.

It all started by a simple thing for example by the roman empire decline affected the christians because the christians taught that the Romans were gona change who they were but they dint
Constantine decreed in the Edict of Milan that Christianity was a legal religion. This was because there was not only hatred of the Christians by the non-Christians, but also dissent among the Christians themselves. He needed domestic tranquility in order to settle his military matters. While the Council of Milan did not settle matters among the Christians to a great extent, it did give them legal status.
