Chronology of the Persecution of Christians from 299-324

The table below gives a separate column for each of the four prefectures of the Roman Empire from 299-324. The rows give a brief summary of the events which occurred each year in the given prefecture. You can click on the “Source Cited” to read an English translation of the original source of the information, usually taken from the Nicene-Post Nicene Father series, but updated into modern English. The colors represent official persecution, i.e., the legal status of Christians, and not necessarily the enforcement of those laws. Though laws against Christians were on the books, they were enforced differently by the various local governments, some of which tried to ignore the edicts, and some of which tried to show their zeal for the empire by taking their persecutions above and beyond what was called for. This caveat is not intended to lessen the severity of the persecution when it was enforced. Also, in AD 260  Emperor Gallienus had approved the owning of property and buildings by the church or the local bishops, in effect making it a legal entity; many of the edicts below involve restitution due to subsequent seizures of such property. The succession of Caesares and Augusti of this time period can be quite confusing, but the following two charts will help to clarify the chronology:

White background represents no imperially-mandated persecution.
Green represents a mild or limited form of imperially-mandated persecution (e.g., the loss of certain rights for certain groups of Christians).
Yellow background represents more virulent persecution (e.g., destruction of Christian property; burning of Scripture and churches).
Red background represents total persecution (widespread imprisonment and loss of life).

299

In Antioch, Diocletian calls upon fortune tellers, who are unable to predict the future, claiming that the presence of Christians is making it impossible to read the omens correctly. Under the influence of Galerius, he orders all members of the imperial court and all soldiers to either make pagan sacrifices or leave their place in the army/imperial court.

Lactantius, De Mortibus Persecutorum 10.6

Eusebius, Historica Ecclesiasica 8 appendix

300
301
Autumn 302
23 Feb. 303

Galerius convinces Diocletian to start persecuting the Christians. Christian assembly is made illegal, all churches and houses with Christian contents are to be burned. Christians who refuse to recant lose legal status and can be tortured. Anyone coming to court has to first make a pagan sacrifice.

Eusebius, Historia Ecclesiastica 8.4

Early Spring 303

Constantius allows no executions, but did burn churches.

Maximian enforces the edict more strictly than Constantius.

Deacon Romanus, in Caesarea, offends Diocletian at Antioch. Apparently some churches had been destroyed, and Romanus made a scene, publicly denouncing former Christians who were on their way to make pagan sacrifices. His tongue is cut out and he is imprisoned (and later executed in Nov. 303).

Eusebius, De Martyribus Palestinae 2

Spring/Summer 303

2nd new edict orders Christian clergy to be arrested and imprisoned. They are to be compelled by torture to make pagan sacrifices.

Eusebius, Historia Ecclesiastica 8.2.5
Autumn 303

Eusebius says that the number of martyrs was uncountable, and that martyrdom was occurring all over in cities and towns across the empire.

3rd edict declares release for all prisoners who sacrificed to the gods, and torture and death for all who refuse. Many are martyred all throughout the three tetrarchies, especially in north Africa and Egypt.

Eusebius, Historia Ecclesiastica 8.6.10
early 304

4th edict orders all inhabitants to gather and sacrifice and pour libations, making it increasingly difficult for Christians to hide.

Eusebius, De Martyribus Palestinae 3.1

1 May 305 Constantius is named Augustus. Maximian retires. Severus is named Caesar. Galerius is named Augustus Diocletian retires, Maximinus is named Caesar.

Lactantius, De Mortibus Persecutorum 19.1 Socrates, Historia Ecclesiastica 1.2

25 July 306

Constantius dies at York, Constantine is named his successor and immediately declares the end of Christian persecution in his realm (Britain, Gaul and Spain) and restores former privileges. Full restitution of property is given to those who had lost it during the persecution.

Eusebius, Vita Constantine 1.21

Socrates, Historia Ecclesiastica 1.2.1

Maxentius provides restitution of property to Christians under his rule.

30 April 311

Galerius rescinds persecution edicts with a deathbed edict. It allows the release of prisoners, freedom of assembly, etc., with no restrictions. Still claiming status as senior member of the Tetrarchy, he issued it for the whole empire, in the name of all the Tetrarchs, but to little effect in the east.

Eusebius, Vita Constantine 1.57

Fall 311

Maximinus takes over Galerius’s territory after his death and continues the persecution.

He orders the mutilation of Christians who refuse to sacrifice to the pagan gods, and orders the burning of churches. (The mutilations account for the amount of crippled and disfigured bishops at Nicaea in 325).

Lactantius, De Mortibus Persecutorum 36.1
26 November 311 Maximinus has the Bishop of Alexandria arrested and executed, thus restarting the martyrdoms in the East. Eusebius, Historia Ecclesiastica 7.32, 9.6.2

Eusebius, Vita Constantine 1.51-2.2

Licinius’ governors use these laws as a pretext for martyring Christians. The Bishop of Pontus is put to death with severe torture.

Eusebius, Vita Constantine 2.1

spring 324 Constantine prepares for war against Licinius Zosimus, New History 2.22
19 September 324

Constantine receives the surrender of Licinius at Nicomedia.

How many Christians were killed in the persecution? It is impossible to say. Timothy Barnes notes a tradition that 660 died in Alexandria alone (Constantine and Eusebius [Cambridge: Harvard University Press, 1981], p. 201). To this day the Coptic church’s calendar begins in the year 284 in remembrance of the Diocletian persecution.

The Edict of Milan, issued by Constantine and Licinius in A.D. 313, officially granted to Christians the freedom to practice their religion without threat of persecution.  The text of the Edict can be accessed here. An even earlier Edict of Toleration for part of the eastern empire, issued in A.D. 311, can be accessed here.
