Persecution of Christians in Roman Egypt

Christians in Roman Egypt experienced repeated persecution, especially under Decius, Valerian, and the tetrarchy, leaving a lasting legacy in church discipline, martyr veneration, and the Coptic calendar.[^1][^2][^3][^4]

Religious and political context

The persecution of Christians in Egypt was closely connected with Roman religious policy and the imperial ruler cult. Authorities sought to demonstrate political loyalty through sacrifice to the empire’s gods, often sparing Christians who complied. Large-scale persecution became a feature of imperial religious policy in the third century.1

Decius and Valerian

Under Decius, between 249 and 251, an imperial decree required sacrifice and libation to the gods, with certificates known as libelli recording compliance. Numerous examples survive from Egypt.2 These ceremonies included offering incense, pouring a libation, and eating sacrificial meat before a local commission; the requirement extended even to people who already held priesthoods in traditional cults.67

Christian responses varied. Dionysius of Alexandria described panic, confusion, and acceptance of the decree, but also resistance and martyrdom. His account names seventeen martyrs and describes Christians killed by hostile crowds or driven into the desert.7

Persecution resumed under Valerian in 257. Dionysius and members of the Alexandrian clergy were deported to Libya, while other Christians suffered more severe penalties. Following Valerian’s capture by the Persians in 260, Gallienus permitted Christianity to continue unmolested, a policy largely maintained until the end of the century.3

The Great Persecution

The Great Persecution began in 303 under Diocletian. Successive edicts intensified repression of Christian leaders and congregations; in Egypt, the prefect Clodius Culcianus was responsible for their implementation.4

The persecution developed in stages. Churches in the countryside were destroyed or dismantled, and measures initially concentrated on clergy and prominent Christians. A fourth edict in 304 required universal sacrifice under threat of punishment, including death. One account emphasizes that many martyrdoms recorded by Eusebius belonged to the subsequent reign of Maximinus rather than Diocletian’s own rule.8

Neither Diocletian’s abdication in 305 nor Galerius’s toleration edict of 311 brought lasting relief in Egypt. Maximinus Daia continued persecution until his defeat by Licinius in 313. Peter I, bishop of Alexandria, was executed on 25 November 311, during the prefecture of Sossianus Hierocles.9

Licinius renewed persecution in 322–323 before his defeat by Constantine in 324. Constantine’s victory inaugurated what the source calls the “Peace of the Church.”10

Evidence and disputed details

Important evidence includes Egyptian papyri and Eusebius’s Ecclesiastical History, which preserves letters by Dionysius of Alexandria and Phileas of Thmuis. Eusebius also reported martyrdoms that he witnessed in Egypt.5

The supplied sources differ over the execution date of Phileas: the martyrology entry reports 4 February 306 from the heading of his Apologia, whereas the persecution survey proposes 4 February 307.511

The number of victims cannot be securely established. One entry regards approximately one million Coptic martyrs as a reasonable estimate, while another explicitly states that this figure lacks strict historical substantiation. A separate survey says reliable victim totals are unavailable and cites an estimate of 2,500–3,000 martyrs throughout the East during the Great Persecution alone; these figures therefore also differ in geographical and chronological scope.121314

Coptic legacy

Disagreements over the readmission of Christians who had sacrificed contributed to lasting divisions, including the Melitian schism in Egypt.1 The Coptic Era of the Martyrs commemorates persecution by beginning with Diocletian’s accession in 284, rather than the outbreak of the Great Persecution in 303.4

Martyr veneration flourished after persecution ended. By about 600, a network of martyrs’ sanctuaries covered Egypt, and shrines such as Abu Mina attracted pilgrims from abroad.15

    there is ample evidence for the large-scale systematic persecution under Decius between 249 and 251. An imperial decree ordered sacrifice and libation to the gods, and certificates (libelli) that these had been performed were required. Many of these documents are known from Egypt.

    After the short reign of Decius and a pause of a few years, persecutions resumed in 257 under Valerianus (253-260). Dionysius and members of the Alexandrian clergy were deported to Libya. Others, including Christian laymen, suffered worse fates. But these actions came to a halt in 260, when Valerianus was defeated and captured by the Sassanids of Persia. His son and successor, Gallienus, permitted Christianity to survive unmolested, a policy largely followed until the end of the third century.

    His pressure, more than anything else, seems to have determined Diocletian to take action, first on 23 February 303, the pagan feast of the Terminalia. In a crescendo of edicts from 24 February 303 to the fourth edict in January/February 304, ever growing repression was applied to the Christians, leaders and flock alike. In Egypt it was the prefect Clodius Culcianus (301-307) who was responsible for the application of the tetrarchic edicts. The persecution left such a mark on Egyptian Christians that in their time reckoning they used the Era of the Martyrs, starting with the accession of Diocl

In VIII.10 he quotes from a letter of Phileas of Thmuis, who died a martyr in the persecution under DIOCLETIAN. According to VIII.9, Eusebius witnessed martyrdoms in Egypt. ... Also first-rate sources are papyri from the Age of Persecution, such as the libelli of the Decian persecution (Bludau, 1931) and the Apologia of Phileas of Thmuis, which contains the conversation between Culcianus, his judge, and the martyr, which was followed, according to

    Both libelli indicate the solemn character of the action, obligatory even to those who already held priesthoods in local cults. ... At Alexandria, Bishop Dionysius paints an awe-inspiring picture of the mixture of panic, confusion, and resigned acceptance of the imperial edict by the mass of the Christian population ... In Alexandria, there was some resistance. Dionysius mentions seventeen martyrs, six significantly being recorded as "Libyans" ...

    In the countryside, churches were destroyed or dismantled ... The second and third edicts of persecution, in the summer and autumn of 303, were aimed at enforcing the conformity of the clergy ... Up to then the persecution had affected "only the presidents of the churches" (Martyrs of Palestine iii.1) or at least only prominent Christians, but the fourth edict that Galerius promulgated in the spring of 304 required all to sacrifice to the gods on pain of punishment, including death. ... The many martyrdoms recorded in Eusebius belong, however, to the reign of Maximin (305-313).

    Neither the abdication of Diocletian and Maximian on 1 May 305 nor Galerius' edict of toleration on 30 April 311 brought lasting relief for the Christians in Egypt. Maximinus Daia (caesar, 305-310; augustus, 310-313) continued the persecution until Constantine and Licinius met at Milan in 313 and pronounced themselves in favor of the toleration and restoration of the Christian church. Only with Maximinus' defeat at the hands of Licinius in 313 did the Great Persecution finally come to a halt. In Egypt, Sossianus Hierocles, prefect in 310/311 (Barnes, 1982, p. 150) is on record as a particularl

    In 322-323, Licinius, preparing for his struggle with Constantine, resumed the persecution of Christians, but without much success, since he was defeated by 324. Constantine's victory inaugurated for the whole Roman Empire a new epoch, the "Peace of the Church," only briefly interrupted by the countermeasures of JULIAN THE APOSTATE (361-363).

    Phileas was executed probably on 4 February 307.

    It is, of course, impossible to assemble the names of all the martyrs who were tortured and executed for refusing to offer incense and libations to the ancient gods and emperors, but a fair estimate of their number would be about 1 million.

    The price that the church in Egypt paid during this dark episode in the history of humanity was very heavy indeed. It has been estimated, though without strict historical substantiation, that the toll reached a million souls, men and women of all walks of life.

    We do not have any reliable data on the number of victims. Frend (1965, p. 537) estimates the number of martyrs in the entire East at between 2,500 and 3,000 in the period of the Great Persecution (303-313).
  15. 15.The Coptic Encyclopedia, Volume 5 — Aziz S. Atiya (Editor in Chief) (p. 494)
    When the Age of Persecution had ended, a flourishing cult of the martyrs grew up in Egypt, with features typical of that country. ... Around the year 600, a network of martyrs' sanctuaries covered the country. ... The sanctuaries of the martyrs Cyrus and John in Menuthis, and especially that of ABU MINA, attracted numerous pilgrims, foreigners among them.
