On April 30, 311, a dying Galerius issued an edict at Nicomedia granting Christians legal standing to assemble, provided they kept public order. “So that they may again be Christians,” the Latin text reads. Wax cracked under seals; a long persecution stopped on paper—and in practice.
What Happened
Five years of political strain and uneven repression had taught hard lessons. On April 30, 311, Galerius—once the enforcer, now mortally ill—dictated a reversal from Nicomedia: Christians could meet again, “provided they do nothing contrary to good order.” The edict acknowledged failure: coercion had not achieved conformity; the state wanted peace [3][4].
Lactantius preserved the Latin, Eusebius a Greek version. Both versions convey a pragmatic tone wrapped in imperial dignity. The wording is careful—rights to assemble, a call for prayers for the emperors, and the condition of public tranquility. The parchment would have been warm from hands; purple seals pressed into wax snapped when the copies were opened for reading in cities like Serdica, Thessalonica, and Antioch [3][4].
Enforcement patterns shifted quickly. Prison doors opened; bishops returned; congregations tested the boundaries with early gatherings. In places where the edicts of 303 had burned hottest—Palestine, Egypt—the change felt like a weather front passing. The sound moved from the crash of demolitions to the low murmur of services, cautious at first, then stronger [2][3].
This was a political as much as a religious act. Galerius needed quiet in the East as rivals multiplied; he needed Christians to stop being a problem category. The Tetrarchy that had tried to engineer obedience by law now tried to buy legitimacy by tolerance. It was late, but it worked enough to matter [3][4].
Why This Matters
The 311 edict legally ended the Diocletianic persecution. It restored Christian assemblies and normalized them as a fact of urban life, while preserving the state’s claim to police public order [3][4].
Within the ideology, law, and religion theme, the reversal shows the regime’s willingness to amend theology by statute. The same chancery that had ordered burnings now invited prayers for imperial health, reframing the relationship between church and state [3][4].
In the broader arc, Galerius’ toleration opened a door Constantine and Licinius would push wide in 313, guaranteeing free worship “to Christians and all others” and ordering restitution. The legal pivot of 311–313 marks the end of the Tetrarchy’s religious war, even as its political war continued [6][5].

People Involved
Key figures who played a role in Galerius’s Edict of Toleration Ends Persecution
Licinius
Licinius, a Balkan soldier and friend of Galerius, was elevated as Augustus at the 308 settlement to stabilize the Tetrarchy’s West. He soon allied with Constantine, married his half-sister Constantia, and co-authored the 313 agreement popularly called the Edict of Milan, guaranteeing free worship and restitution of Christian property throughout the empire. Though later a rival of Constantine, in this timeline he is the indispensable partner who turned a weary toleration into a formal policy and broke Maximinus Daia’s resistance in the East.
Maximinus Daia
Maximinus Daia, a nephew of Galerius from the Balkan countryside, was raised to Caesar in 305 and ruled Syria and Egypt with a heavy hand. A staunch pagan, he intensified the Great Persecution in his territories, encouraged anti-Christian petitions, and resisted concessions even after Galerius’s 311 edict of toleration. When Constantine and Licinius agreed on the 313 religious settlement, Maximinus defied it, only to be defeated by Licinius and die in flight later that year. In this timeline he is the last holdout of the old order—ambitious, coercive, and ultimately swept aside.
Constantine I
Constantine, son of Constantius, was acclaimed by the army at York in 306 and soon transformed the Tetrarchy’s civil wars into a new imperial order. He defeated rival claimants, confronted Maxentius and Maximinus Daia, and—together with Licinius—issued the 313 settlement known as the Edict of Milan, guaranteeing free worship and the restitution of Christian property. In this timeline he stands at the hinge: the Tetrarchy’s promise of order collapses into rivalry, and Constantine reframes legitimacy around personal victory and religious toleration, opening the path to a Christian empire.
