Why did Emperor Julian attempt to restore pagan worship in the Roman Empire?

Emperor Julian, often called "the Apostate," attempted to restore pagan worship in the Roman Empire primarily due to his deep-seated devotion to Hellenic culture and his personal animosity toward the Christian leadership that had decimated his family.12

His motivations and methods included:

• Philosophical Conviction: Julian was a committed adherent of Neoplatonism and a practitioner of theurgy. He sought to elevate paganism into an official, organized religion, modeling its hierarchy after the structure of the Christian church, with himself as the supreme pontiff.12
• Cultural Preservation: He viewed Christianity as a threat to the classical heritage of Greece and Rome. Consequently, he prohibited Christians from teaching classical literature and philosophy, arguing they had no right to interpret authors like Homer or Plato.12
• Political Strategy: By restoring pagan shrines and favoring pagans for high official appointments, he aimed to reverse the Christianization of the government and military initiated by his predecessors. He also sought to weaken Christianity by allowing exiled bishops to return, hoping to incite internal doctrinal disputes.12

Ultimately, Julian viewed the revival of paganism as a means to achieve national reconciliation and restore the glory of the Roman past.2
