He became the emperor of the western part of the Roman Empire after winning a war on an usurper emperor. In 324 he became sole emperor after wining a war against the emperor of the eastern part of the empire. Constantine is known mainly for being the first Roman emperor who supported Christianity. In 313. together with his co-emperor Licinius, he issued the Edict of Milan, which aimed at completing the ending of the Great Persecution of Christians which had been decreed by the Edict of Toleration by the emperor Galerius of 311. He tried to arbitrate disputes between rival Christian doctrines by holding synods and ecumenical councils, the most important of which was the First Council of Nicaea. He built a number of Christian churches, most notably the original St Peter's Basilica (Old St Peter's) and the Lateran archibasica (which was the first papal residence) in Rome, Church of the Holy Sepulchre in Jerusalem and the Church of the Holy Apostles in Constantinople . He also opened high office in the imperial administration to Christians.

Constantine the Great did not spread Christianity. By the time of his reign, Christianity had already spread and had already become the religion of the masses in the Roman Empire, although there were still many pagans. Constantine supported the Christians. He arbitrated between different doctrines of Christianity, promoted Christians in the imperial administration and built Christian Churches. The most notable of these churches were 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.
Some of the accomplishments of Constantine I (or the Great) were: 1) Becoming the sole emperor of the whole of the Roman Empire. Constantine started off being a junior emperor in charge of Britain, Gaul and Spain. He then won a civil war against Maxentius, a usurper emperor who had taken over Italy (after which he became emperor of the west) and another civil war against his co-emperor Licinius (the emperor of the east). 2) Finalising the end of the great Persecution of Christians. The edict of Milan agreed with Licinius reiterated the toleration of the Christians decreed two years earlier by the Edict of Toleration by (emperor) Galerius and provided for the return of Christian property which had been confiscated during the persecution. 3) Moving the Capital of the eastern part of the Roman Empire from Nicomedia (in north-western Turkey) to the nearby Byzantium. Constantine redeveloped it and renamed it Constantinople (City of Constantine). 4) Resolving the problem of inflation which had been plaguing the empire for a long time and caused its economy to decline. Constantine did so by amassing gold and issuing a new gold coin (the solidus) which proved to be stable. 5) Building important Christian churches. Constantine built 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.
