The last Western Roman Emperor, Romulus Augustulus is deposed on September 4, 476, by the Germanic chieftain Odoacer (Adovacar), a barbarian member of the Germanic tribe Siri and former commander in the Roman army.
Odoacer entered the city of Rome unopposed, dethroned emperor Romulus Augustus and declared himself King of Italy, with the approval of the Roman Senate and the eastern Emperor Zeno. Although Roman rule continued in the East, the crowning of Odoacer marked the end of the original Roman Empire centered in Italy, although there was some resurgence and expansion of the power of Rome to the west.
