What event is marked by AD 476?

The year AD 476 is significant because it marks the commonly accepted date for the fall of the Western Roman Empire. This event is characterized by the deposition of the last Roman emperor, Romulus Augustulus, by the Germanic king Odoacer. This transition marked a pivotal moment in history, as it symbolized the collapse of Roman authority in the West and the end of ancient Roman civilization's dominance in that region.

While the founding of Constantinople, the signing of the Magna Carta, and other events had profound impacts on history, they occurred well after this significant year. The fall of the Western Roman Empire led to the onset of the Middle Ages in Europe, setting the stage for the development of various successor kingdoms and the eventual emergence of nations. Thus, AD 476 is a landmark date that signifies the end of an era and the beginning of a new chapter in European history.
