Roman Religion's Role in Empire: Tolerance, Persecution, and the Rise of Christianity

publication · 2026-10-16

According to The Collector, Roman religion acted as both a cohesive and disruptive element throughout five centuries of imperial governance. The polytheistic belief system incorporated foreign gods such as Mithras and Isis, promoting expansion through its inclusive nature. A key aspect was Pax Deorum, which ensured prosperity through appropriate rituals. Emperors, particularly Augustus, leveraged religion to validate their power, founding the imperial cult with temples in Rome and elsewhere. Between 70 and 82 emperors reigned, each possessing distinct religious perspectives. Significant figures included Elagabalus, Nero, Domitian, and Diocletian, who notably persecuted Christians. Claudius expelled Jews, and Jerusalem fell in AD 70. The Edict of Milan in AD 313 marked a pivotal change for Christianity under Constantine, while Theodosius I later established it as the state religion.
