How did the Roman Empire fall?
assistant
The Roman Empire fell because it lost the wars against the Huns and the Goths. In the 4th century, the Huns defeated the Roman Empire in Central Asia and then moved westward. The Goths, who had been living in Eastern Europe, moved westward and attacked the Roman Empire. The Romans were not able to defeat the Goths and the Huns, and the Roman Empire fell in 476 AD.
