Diocletianic Persecution

The Diocletianic Persecution was a series of anti-Christian measures launched in the Roman Empire in 303. It involved church demolitions, scripture seizures, imprisonment, and demands for sacrifice, with enforcement varying across regions and emperors.

Edict Against the Christians: A Roman imperial decree of 303 ordering churches demolished, scriptures burned, and Christians deprived of legal rights. This first edict established the principal measures used to attack Christian communities.
Diocletian: Roman emperor from 284 to 305 who reorganized imperial government and initiated the persecution of Christians in 303. His government issued the first anti-Christian edicts and set the campaign in motion.
Constantius Chlorus: A Roman emperor from 305 to 306 who ruled the western territories and limited persecution there. His comparatively restrained enforcement made the western provinces an exception to harsher policies.
Edict of Milan: A 313 agreement associated with Constantine and Licinius that granted religious freedom and restored confiscated Christian property. It marks a later imperial turn toward toleration and restitution rather than coercion.
Roman Imperial Cult: Public rituals honoring Roman emperors and the imperial order, often involving sacrifices and vows. Sacrifice to the gods and imperial order became a test of compliance.
Tetrarchy: The system of imperial rule established by Diocletian, with two senior emperors and two junior emperors. The division of imperial authority helps explain why enforcement differed across rulers and territories.
Maximian: Roman emperor from 286 to 305 who ruled the western empire alongside Diocletian. He was one of the senior rulers responsible for implementing the initial imperial policy.
Edict of Serdica: A toleration edict issued by Galerius in 311 that allowed Christians to worship, subject to conditions. It formally ended persecution under Galerius while revealing the limits of early toleration.
Roman governor: A Roman official who governed a province and exercised administrative and judicial authority. Provincial officials carried out edicts, with implementation shaped by local circumstances.
Galerius: Roman emperor from 305 to 311 who enforced the persecution in the eastern empire and issued its first general toleration edict. He pressed for anti-Christian measures and later ended the campaign in his territories.
