Constantine the Great: Emperor, Christianity, and Rome

~11 min read 6 sections History · Ancient Rome
Abstract

This paper examines the life and legacy of Constantine I (272–337 AD), the first Roman Emperor to legalize Christianity and reshape the religious and political landscape of the late Roman Empire. The paper covers his origins and early career under the Tetrarchy, his military campaigns and rise to sole emperor, and his pivotal religious policies including the Edict of Milan (313) and the First Council of Nicaea (325). It also analyzes the social and legal reforms enacted during his reign, his complex relationship with both Christianity and paganism, and the lasting consequences of his rule for the Church, the empire, and European history.

  • Religious Policy, Tolerance, and the Edict of Milan: Edict of Milan, church privileges, and clerical power

✍️ How to write this paper — guide, tools & examples ▾

What makes this paper effective

  • The paper integrates primary source quotations — including Symmachus's plea for religious tolerance and eyewitness accounts of Constantine's vision — to ground claims in historical testimony rather than assertion alone.
  • It balances political and religious dimensions of Constantine's reign, showing how his Christian policies had unintended institutional consequences (e.g., the growth of clerical power) alongside intended ones.
  • The paper maintains nuance by acknowledging scholarly skepticism — for example, questioning whether Constantine's vision before the Battle of Milvian Bridge was genuine — rather than presenting a one-sided narrative.

Key academic technique demonstrated

The paper demonstrates effective use of embedded quotation to support historical argument. Rather than paraphrasing all sources, the writer selects specific quoted passages at key argumentative moments — such as the debate over Constantine's vision and the unintended growth of episcopal power — allowing the sources to speak while the surrounding analysis provides interpretive context.

Structure breakdown

The paper moves chronologically and thematically: it opens with biographical background, proceeds through Constantine's military rise, then pivots to his religious significance, examining the Edict of Milan, church-state relations, legal reforms, and finally the Council of Nicaea. Each section builds on the last, culminating in the theological dispute over Arianism that forced Constantine to define orthodox Christianity through the Nicene Creed.

Introduction: Who Was Constantine?

Flavius Valerius Aurelius Constantinus, born February 27, 272, is commonly known as Constantine I or Constantine the Great. He was proclaimed Augustus by his troops on July 25, 306, and ruled an ever-growing portion of the Roman Empire until his death. Constantine is famous for his rebuilding of Byzantium as Nova Roma (New Rome), which was always popularly called "Constantine's City" (Constantinopolis, or Constantinople). With the Edict of Milan in 313, Constantine and his co-Emperor Licinius removed all legal burden from Christianity. By personally convening the Council of Nicaea in 325, Constantine began the Roman Empire's unofficial sponsorship of Christianity — a major factor in that religion's spread. His reputation as the "first Christian Emperor" was promoted by Lactantius and Eusebius of Caesarea, and gained ground in succeeding generations.

He was born at Naissus (today's Niš, in Serbia) in Upper Moesia, to Constantius I Chlorus, who was of Greek descent, and Flavia Iulia Helena, an innkeeper's daughter who was only about sixteen years old at the time. Helena "may not have been married to Constantius I Chlorus — who, as a high officer, could have found it difficult to marry a non-Roman wife — although some modern authorities refuse to accept this view, out of a pious determination to regard Constantine as legitimate."

His father left his mother in 292 to marry Flavia Maximiana Theodora, daughter or stepdaughter of Western Roman Emperor Maximian. Theodora would give birth to six of Constantine's half-siblings, including Julius Constantius. Family influence is thought to account for his personal embrace of Christianity: Helena is said to have probably been born a Christian, though virtually nothing is known of her background except that her mother was an innkeeper's daughter and her father a successful soldier — a career that excluded overt Christians. Certainly Helena demonstrated extreme piety later in life during her trip to Palestine, where she reportedly discovered the True Cross and established basilicas.
