Constantine is counted the most important of the later Roman emperors because of:

  • Christianity
    Constantine was the 1st Roman emperor to support Christianity and become Christian. From the time of Constantine, Christianity became the Roman religion, with a temporary setback when his nephew Julian tried to reinstate the old Roman polytheistic beliefs, which we refer to as paganism.

  • Tolerance
    Constantine proclaimed the Edict of Milan, in 313, granting religious freedom to all.
  • Symbolism
    Constantine was victorious against Emperor Maxentius at the Milvian Bridge, which was significant for its Christian symbolism.
  • Building
    Constantine created a new central, Christian city for the Roman Empire at Byzantium (Constantinople [later, Istanbul]).

Family and Birth of Constantine:

Flavius Valerius Constantinus, who became the Emperor Constantine the Great, was born on Feb. 27, c. 280, in Naissus, in the province of Moesia Superior (Serbia) [see map of Macedonia, Moesia, Dacia, and Thracia]. Constantine's mother was named Helena, described as a barmaid, and his father was an officer named Constantius. Constantius would become the Emperor Constantius I (Constantius Chlorus) and Constantine's mother would become famous as the canonized St. Helena. Helena is thought to have found a portion of the cross of Jesus.

Flavia Julia Constantia was one of Constantine's 3 half-sister and 3 half-brothers, the product of his father's marriage to a second woman of less dubious background than Helena's. By the time Constantius became governor of Dalmatia, he required a pedigreed wife, Theodora (Flavia Maximiana Theodora). She was a daughter of Maximian [see Tetrarchy Emperors]. Constantius then shuffled his son Constantine and Helena off to the eastern emperor, Diocletian, in Nicomedia. [Paul Stephenson's Constantine; New York: The Overlook Press (2010).]

Constantine married twice. By the 1st, he had a son Crispus. By the 2nd, Constantine II, Constans, and Constantius II.

In Hoc Signo Vinces:

The story goes that Constantine had a vision of the words "in hoc signo vinces" ('in this sign you will conquer', but in Greek: εν τούτῳ νίκα) upon a cross and that this vision prompted Constantine to pledge to convert if he actually did win the battle at the Milvian Bridge. Since Constantine was the victor, the vision led to his conversion to Christianity. Constantine probably experienced his great "in hoc signo vinces" vision in 312. On December 25, 323, Constantine exempted Christians from pagan lustration rites [Stephenson].

Constantine the Great Rules Alone:

Constantine had ruled jointly with Licinus, who was married to Constantine's half-sister Flavia Julia Constantia, but Constantine defeated Licinus, who was based on the Sea of Marmara, in 324. Licinus said Constantine had violated treaty terms with the Sarmatians, whom Constantine had fought, in 323, applying the title of Sarmatian conqueror (Sarmaticus Maximus) to himself.

The first battle between Constantine and Licinus, on July 3-4 of 324, was at Adrianople, in Thrace. Constantine won. Next they fought at sea, in the Hellespont. Constantine's son Crispus was victorious in this encounter with Licinius' admiral Amandus. Licinus surrendered at Chrysopolis on the 18th of September.

Constantine created Constantinople on the site of Byzantium to celebrate his victory. [Stephenson]

Constantine on Heresy:

Constantine was not yet a baptized Christian when he settled matters of Christian dogma and the Arian Controversy at the First Nicene Council (First Council of Nicaea), which ended on August (or July) 25, 325. As a result of his initial decision against the Arians, Constantine exiled his friend Eusebius for holding an heretical position. Constantine later revised his opinion and recalled Eusebius.

It was from 325 that Constantine enjoyed sole reign in the Roman empire, having defeated and executed his co-emperor Licinius, who had reneged on the Edict of Milan.

Death of Constantine:

Constantine died in 22 May, 337 at Nicomedia, shortly after his baptism by the Arian bishop, his friend Eusebius of Nicomedia.

Constantine and Christianity:

Most people consider Constantine a Christian from the Milvian Bridge in 312, but he wasn't baptized until a quarter century later. Today, Constantine wouldn't count as a Christian in many forms of Christianity without the baptism, but it's even less clear in the period of Classical Christianity.
