The Roman Empire began in 27 BC with Augustus, the first emperor of Rome. It eventually split in half in 395 AD. The Western Roman Empire, including the city of Rome itself, fell in 476 AD. The Eastern Roman Empire, or the Byzantine Empire was centered on Constantinople, not Rome.
The point is Rome did not last 1,480+ years as you and the other poster claimed, not even close. Odoacer conquered Rome and became the first barbarian king of Italy in 476 AD.
