Constantine The Great

Flavius Valerius Aurelius Constantinus (27 February c. 272 – 22 May 337), commonly known in English as Constantine I, Constantine the Great, or (among Eastern Orthodox, Oriental Orthodox and Byzantine Catholic Christians) Saint Constantine, was Roman Emperor from 306, and the undisputed holder of that office from 324 until his death in 337. Best known for being the first Christian Roman Emperor, Constantine reversed the persecutions of his predecessor, Diocletian, and issued (with his co-emperor Licinius) the Edict of Milan in 313, which proclaimed religious toleration throughout the empire.
The Byzantine liturgical calendar, observed by the Eastern Orthodox Church and Eastern Catholic Churches of Byzantine rite, lists both Constantine and his mother Helena as saints. Although he is not included in the Latin Church’s list of saints, which does recognize several other Constantines as saints, he is revered under the title “The Great” for his contributions to Christianity.
Constantine also transformed the ancient Greek colony of Byzantium into a new imperial residence, Constantinople, which would remain the capital of the Byzantine Empire for over a thousand years.

As the Emperor who empowered Christianity throughout the Roman Empire and moved the Roman capital to the banks of the Bosphorus, Constantine was a ruler of major historical importance, but he has always been a controversial figure. The fluctuations in Constantine’s reputation reflect the nature of the ancient sources for his reign. These are abundant and detailed, but have been strongly influenced by the official propaganda of the period, and are often one-sided. There are no surviving histories or biographies dealing with Constantine’s life and rule. The nearest replacement is Eusebius of Caesarea’s Vita Constantini, a work that is a mixture of eulogy and hagiography. Written between 335 and circa 339, the Vita extols Constantine’s moral and religious virtues. The Vita creates a contentiously positive image of Constantine, and modern historians have frequently challenged its reliability. The fullest secular life of Constantine is the anonymous Origo Constantini. A work of uncertain date, the Origo focuses on military and political events, to the neglect of cultural and religious matters.

Lactantius’ De Mortibus Persecutorum, a polemical Christian pamphlet on the reigns of Diocletian and the Tetrarchy, provides valuable but tendentious detail on Constantine’s predecessors and early life. The ecclesiastical histories of Socrates, Sozomen, and Theodoret describe the ecclesiastic disputes of Constantine’s later reign. Written during the reign of Theodosius II (408–50), a century after Constantine’s reign, these ecclesiastic historians obscure the events and theologies of the Constantinian period through misdirection, misrepresentation and deliberate obscurity. The contemporary writings of the Orthodox Christian Athanasius and the ecclesiastical history of the Arian Philostorgius also survive, though their biases are no less firm.
The epitomes of Aurelius Victor (De Caesaribus), Eutropius (Breviarium), Festus (Breviarium), and the anonymous author of the Epitome de Caesaribus offer compressed secular political and military histories of the period. Although pagan, the epitomes paint a favorable image of Constantine, but omit reference to Constantine’s religious policies. The Panegyrici Latini, a collection of panegyrics from the late third and early fourth centuries, provide valuable information on the politics and ideology of the tetrarchic period and the early life of Constantine. Contemporary architecture, like the Arch of Constantine in Rome and palaces in Gamzigrad and Córdoba, epigraphic remains, and the coinage of the era complement the literary sources.

Constantine received a formidable education at Diocletian’s court, where he learned Latin literature, Greek, and philosophy. The cultural environment in Nicomedia was open, fluid and socially mobile, and Constantine could mix with intellectuals both pagan and Christian. He may have attended the lectures of Lactantius, a Christian scholar of Latin in the city. Because Diocletian did not completely trust Constantius—none of the Tetrarchs fully trusted their colleagues—Constantine was held as something of a hostage, a tool to ensure Constantius’ best behaviour. Constantine was nonetheless a prominent member of the court: he fought for Diocletian and Galerius in Asia, and served in a variety of tribunates; he campaigned against barbarians on the Danube in 296, and fought the Persians under Diocletian in Syria (297) and under Galerius in Mesopotamia (298–99). By late 305, he had become a tribune of the first order, a tribunus ordinis primi.
