Romulus Augustulus
Flavius Romulus Augustus (c. AD 460 – after AD 476; possibly still alive as late as AD 507), 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.
Prince-elector
From the 13th century onwards, the Prince-Electors had the privilege of electing the King of the Romans, who would be crowned by the Pope as Holy Roman Emperor. Charles V was the last to be a crowned Emperor (elected 1519, crowned 1530); his successors were elected Emperors directly by the electoral college, each being titled "Elected Emperor of the Romans" (; ). In practice, every emperor from 1440 onwards (except for Charles VII and Francis I) came from the Austrian House of Habsburg, and the Electors merely ratified the Habsburg succession.
