A year defined by the beginning of Byzantine Iconoclasm, as Emperor Leo III ordered the removal of religious images, triggering a bitter theological and political controversy that would divide the empire for over a century.

- The iconoclast policy provoked fierce opposition from monks, many clergy, and the general population, who venerated icons as sacred objects and conduits of divine grace.
- Pope Gregory II condemned the iconoclast policy, deepening the rift between the papacy in Rome and the Byzantine emperor in Constantinople.
- The estimated world population was approximately 225 million.
Geopolitics & Diplomacy
- The Iconoclasm controversy weakened Byzantine control over Italy, as the papacy increasingly looked to the Frankish kingdoms for protection rather than to Constantinople.
