What role did religion play in the rise and fall of the early middle ages empires?

The decline of Rome dovetailed with the spread of Christianity, and some have argued that the rise of a new faith helped contribute to the empire’s fall. The Edict of Milan legalized Christianity in 313, and it later became the state religion in 380. These decrees ended centuries of persecution, but they may have also eroded the traditional Roman values system. Christianity displaced the polytheistic Roman religion, which viewed the emperor as having a divine status, and also shifted focus away from the glory of the state and onto a sole deity. Meanwhile, popes and other church leaders took an increased role in political affairs, further complicating governance. The 18th-century historian Edward Gibbon was the most famous proponent of this theory, but his take has since been widely criticized. While the spread of Christianity may have played a small role in curbing Roman civic virtue, most scholars now argue that its influence paled in comparison to military, economic and administrative factors.
