This historian begs to differ with the charged that Flavius Odoacer was responsible for the demise of the western Roman empire.
"Although everyone from schoolchildren to scholars now learn that the Western Roman Empire fell in 476, 5th century Romans did not see anything particularly special about Odoacer’s coup. Nine different Western Roman emperors had risen and fallen since 455 and most of them had been overthrown by barbarian commanders like Odoacer. In four cases, the barbarian generals toppled one emperor and delayed appointing another. One of these imperial vacancies stretched for 20 months, a span longer than the entire reigns of more than 20 previous Roman emperors. Even Romulus Augustus himself was a usurper who assumed the imperial office after an imperfectly executed coup that left Julius Nepos, the legitimate emperor Romulus replaced, still in charge of Western Roman imperial territories in what is now Croatia. In other words, while the West had lost an imperial usurper in 476, it still had a legitimate Roman emperor.
Odoacer maintained most of the structures of the Roman government during the nearly 17 years he controlled the state. The Senate continued to meet in Rome just as it had for nearly a millennium. Latin remained the language of administration. Roman law governed the land. Roman armies continued to fight and win victories on the frontiers. And Roman emperors appeared on the coins that Odoacer minted. These coins showed Julius Nepos at first and then, after Nepos’s death in 480, they featured the busts of the Eastern Roman emperors who reigned in Constantinople."
