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.
Coronations in Europe
Since Charlemagne in 800, Holy Roman Emperors were crowned by the pope until 1530, when Charles V became the last Holy Roman Emperor to be crowned by the Pope, at Bologna. Thereafter, until the abolition of the empire in 1806, Imperial coronations were held in Frankfurt and were performed by the Spiritual Princes-Electors,the Archbishops of Cologne, Mainz and Trier. Later rulers simply proclaimed themselves "Electus Romanorum Imperator" or "Elected Emperor of the Romans", without the formality of a coronation by the Pontiff.
