query: Who was the last emperor of the Roman Empire?
passage: Romulus Augustulus
Flavius Romulus Augustus (c. AD 460 – after AD 476; possibly still alive as late as AD 507),[3] known derisively and historiographically as Romulus Augustulus, was the Roman emperor who ruled the Western Roman Empire from 31 October 475 until 4 September 476. He is often described as the "last Western Roman emperor", though some historians consider this to be Julius Nepos. His deposition by Odoacer traditionally marks the end of the Roman Empire in the West, the end of Ancient Rome, and the beginning of the Middle Ages in Western Europe.
passage: Wife of Julius Nepos
The wife of Julius Nepos was the last empress of the Roman Empire in the West, whose husband reigned from 474 through 480, although he was in exile from his capital after 475. His surname, Nepos (), he obtained through his marriage. His wife's given name is not in any primary source, all of which report her as the "neptis" of Leo I the Thracian of the Roman Empire in the East (457–74), and his spouse Verina. The word "neptis" could translate as granddaughter, niece or (close) relative, but it is usually assumed that Julius' wife was Leo's niece, and more likely related by blood to Verina rather than Leo. The historian Malchus reports, "Verina also joined in urging this, giving a helping hand to the wife of Nepos, her relative".
