In 476, Odoacer, leader of the foederati in the West, had staged a coup against the rebellious "magister militum" Orestes, who was seeking to have his son Romulus Augustulus recognized as Western Emperor in place of Emperor Julius Nepos. Orestes had reneged on the promise of land in Italy for Odoacer's troops, a pledge made to ensure their neutrality in his attack on Nepos. After executing Orestes and putting the teenage usurper in internal exile, Odoacer paid nominal allegiance to Nepos (now in Dalmatia) while effectively operating autonomously, having been raised to the rank of patrician by Zeno. Odoacer retained the Roman administrative system, cooperated actively with the Roman Senate, and his rule was efficient and successful. He evicted the Vandals from Sicily in 477, and in 480 he occupied Dalmatia after the murder of Julius Nepos.
