These policies and preoccupations culminated in Diocletian's Tetrarchy: the empire was divided into Western and Eastern administrative blocs, each with an Augustus (senior emperor), helped by a Caesar (junior emperor) as Augustus-in-waiting. Provinces were divided and subdivided: their imperial bureaucracy became extraordinary in size, scope and attention to detail. Diocletian was a religious conservative. On his accession in AD 284, he held games in honour of the "divus" Antinous. Where his predecessors had attempted the persuasion and coercion of recalcitrant sects, Diocletian launched a series of ferocious reactions known in Church history as the Great Persecution. According to Lactantius, this began with a report of ominous haruspicy in Diocletian's "domus" and a subsequent (but undated) dictat of placatory sacrifice by the entire military. A date of 302 is regarded as likely and Eusebius also says the persecutions of Christians began in the army. However Maximilian's martyrdom (295) came from his refusal of military service, and Marcellus' (298) for renouncing his military oath. Legally, these were military insurrections and Diocletian's edict may have followed these and similar acts of conscience and faith. An unknown number of Christians appear to have suffered the extreme and exemplary punishments traditionally reserved for rebels and traitors.
