Diocletian worked hard to pull together the Roman Empire from the brink of collapse but remember, his strategy was to return the Empire to some mythic past that really never existed in the first place. But that meant something had to be done about this new pesky religion that had shown up, one that centered an executed criminal. Something must be done about Christianity. Thus began The Great Persecution and the Cult of Martyrs that would grow to become the practice of saints. But even without the religious troubles, there was unrest brewing in the empire. Diocletian and Maximius retired, only for their sons to throw the empire back into civil war.
