Historical synthesis
What happened, and why does it matter?
From 303 imperial edicts ordered destruction of churches and Scriptures, loss of legal status, imprisonment of clergy and sacrifice. Enforcement differed by region; the persecution generated both a vast martyr memory and later disputes over clergy accused of surrendering sacred books.
The subject becomes intelligible when doctrine, worship, government and political circumstance are kept in relation without being treated as identical causes. What legal or local mechanism produced The Great Persecution under Diocletian, how did Christians respond, and which details belong to contemporary record rather than later hagiography?
Imperial or civic authorities, local clergy, confessors and families all affect the course of persecution. local church, imperial administration, martyrs and confessors, episcopal clergy reveal how policy was enforced in Roman Empire. In this dossier that institutional frame is tested specifically against The Great Persecution under Diocletian.
Its historical horizon is tested against Valerian Persecution, Edict of Milan and the Peace of the Church, Neronian Persecution and the Martyrdom of Peter and Paul and Christians under Domitian. These connections show antecedent, parallel development and reception without collapsing separate events into one narrative.
The source base begins with Eusebius, Historia ecclesiastica VIII–IX. It is compared with Lactantius, De mortibus persecutorum 11–16. The difference between these genres is material: one may establish a promulgated act, another a reported experience, argument or later reception. In this dossier the comparison is used specifically to reconstruct The Great Persecution under Diocletian, not as a reusable conclusion for the whole period.
