When did the Roman Empire fall?

The Roman Empire began to decline in the 3rd century AD due to a variety of factors such as political instability, economic troubles, and external pressures from invading forces. However, the official end of the Western Roman Empire is marked by the deposition of the last emperor, Romulus Augustus, in 476 AD. The Eastern Roman Empire, also known as the Byzantine Empire, continued on until its own collapse in 1453. The fall of the Roman Empire had significant impacts on world history, including the transition from ancient to medieval times and the development of European civilization.
