Soon after the end of the Persian War, Diocletian ordered a persecution of the Christians (303), the harshness of which would be incomprehensible in such a sagacious ruler if we did not know, from other actions, how jealously he watched his authority. Every act of disobedience, every attempt at rebellion, he punished with inexorable severity and cruelty, often in a paroxysm of rage giving orders which had the most fatal results. For instance, in Egypt, after the defeat of the usurper Achilleus, he exterminated all the latter’s adherents and destroyed entire towns, the inhabitants of which had shown themselves insubordinate. When a certain Eugenius had set himself up as emperor in Syria, he caused the inhabitants of Antioch to expiate this presumption by suffering revolting cruelties, although they had helped to suppress the insurrection and had killed the rebel.
Diocletian’s persecution of the Christians at first only struck at the Christians in the army. Latterly, whenever they had to witness a heathen sacrifice they had fastened the sign of the cross to their helmets, so as to prevent the raising of the devil, which, according to their belief, took place at the inspection of the entrails of the victim; they thereby roused the anger of one of the high priests, and he incited the emperor against them. Nevertheless Diocletian did not yet determine on cruel measures, as he was wise and thoughtful enough to perceive that the new sect could not be rooted out, on account of its wide diffusion, and that to persecute it would occasion dangerous disturbances throughout the kingdom. On this account he would not have determined on a general persecution had not Galerius, who was passionately attached to the mystical fantasies of the Phrygian worship, drawn him into it by every sort of intrigue. Even then his orders were directed less against the persons of the Christians than against their religion and against the acknowledgment of their congregation as a body.
The Christians were to fill no public offices, and not to seek justice before the tribunals; their churches were to be closed or pulled down, crosses and pictures of Christ were not allowed. This ordinance was publicly posted up in Nicomedia, where Diocletian and Galerius were. A man of great distinction among the Christians tore it down in full daylight with loud mockery, and it was only then that Diocletian, who, as soon as he thought his imperial dignity touched, became terribly cruel, gave free scope to a cruel persecution of individuals. His rage was further increased by a fire in the imperial palace, which, as it seems not unjustly, was attributed to the Christians. The execution of the imperial orders was left to the soldiers and the populace, and a number of Christians suffered death. These extreme measures were restricted to the East, to Africa, and to the south of Europe.
ABDICATION OF DIOCLETIAN AND MAXIMIAN; THE TWO NEW CÆSARS
[303-306 A.D.]
Soon after the beginning of this persecution Diocletian fell ill, and his illness, which lasted almost a year, became so dangerous that the news of his death was repeatedly spread. When he recovered, traces of a weakening of intellect often showed themselves, and made it impossible for him to continue to conduct the business of administration. Therefore in May, 305, he laid down the government, and at the same time Maximian did likewise, Galerius having previously extorted from him a promise to abdicate.

The two cæsars, Galerius and Constantius Chlorus, were then acclaimed as emperors. The former immediately named two new cæsars without consulting his co-rulers, but in so doing paid no heed to either Maximian’s son Maxentius, or the son of Constantius, afterwards the emperor Constantine the Great. It is probable that his own father did not deem the former worthy to ascend the throne; the latter had already distinguished himself in the field, and possessed the favour of Diocletian, but he was also friendly towards the Christians, and seemed dangerous to Galerius. The new cæsars were rough officers, undistinguished by any superiority of merit. One of them, Severus, received the government of Africa and Italy; the other, Maximinus, was invested with Syria and Egypt.
