§ 55. The Reorganization of the Empire by Diocletian
After a period of anarchy Diocletian (284-305) undertook a reorganization of the Empire for the sake of greater efficiency. Following a precedent of earlier successful emperors, he shared (285) the imperial authority with a colleague, Maximianus, who in 286 became Augustus of the West. As the greatest danger seemed to lie in the East, Diocletian retained the Eastern part of the Empire, and having already abandoned Rome as the imperial residence (284), he settled in Nicomedia in Bithynia. To provide for a succession to the throne more efficient than the chance succession of natural heirs, two Cæsars were appointed in 293, Constantius Chlorus for the West, and Galerius, the son-in-law of Diocletian, for the East. Constantius at once became the son-in-law of Maximianus. These Cæsars were to ascend the throne when the Augusti resigned after twenty years' reign. The scheme worked temporarily for greater efficiency, but ended in civil war as the claims of natural heirs were set aside in favor of an artificial dynasty. At the same time the system bore heavily [pg 258] upon the people and the prosperity of the Empire rapidly declined.

When Diocletian, the author of crimes and deviser of evils, was ruining all things, not even from against God could he withhold his hand. This man, partly by avarice and partly by timidity, overturned the world. For he made three persons sharers with him in the government. The Empire was divided into four parts, and armies were multiplied, since each of the four princes strove to have a much larger military force than any emperor had had when one emperor alone carried on the government. There began to be a greater number of those who received taxes than of those who paid them; so that the means of the husbandmen were exhausted by enormous impositions, the fields were abandoned, and cultivated grounds became woodlands, and universal dismay prevailed. Besides, the provinces were divided into minute portions and many presidents and prefects lay heavy on each territory, and almost on every city. There were many stewards and masters and deputy presidents, before whom very few civil causes came, but only condemnations and frequent forfeitures, and exactions of numberless commodities, and I will not say often repeated, but perpetual and intolerable, wrongs in the exacting of them.
§ 56. The Diocletian Persecution
The last great persecution was preceded by a number of laws aimed to annoy the Christians. On March 12, 295, all soldiers in the army were ordered to offer sacrifice. In 296 sacred books of the Christians were sought for and burnt at Alexandria. In 297 or 298 Christian persecutions began in the army, but the great persecution itself broke out in 303, as described below. Among other reasons for energetic [pg 259] measures in which Galerius took the lead, appears to have been that prince's desire to establish the unity of the Empire upon a religious basis, which is borne out by his attempts to reorganize the heathen worship immediately after the cessation of the persecution. In April, 311, the edict of Galerius, known as the Edict of the Three Emperors, put an official end to the persecution. In parts of the Empire, however, small persecutions took place and the authorities attempted to attack Christianity without actually carrying on persecutions, as in the wide-spread dissemination of the infamous “Acts of Pilate,” which were posted on walls and spread through the schools. In the territories of Constantius Chlorus the persecution had been very light, and there was none under Constantine who favored Christians from the first.
