Odoacer became king on the 23rd of August 476 when Germanic foederati proclaimed him rex after defeating Orestes at Placentia. He advanced to Ravenna compelling Romulus Augustulus to abdicate on the 4th of September 476 which marks the traditional end of the Western Roman Empire.
Debate continues over whether Odoacer's father Edeco was Hunnic or Germanic in origin. His brother Hunulf carries a name generally understood as Hun wolf within Germanic tradition yet experts suggest the first part hun may refer to the Huns themselves rather than just a generic descriptor.
Odoacer died ten days after Theodoric entered Ravenna on the 5th of March 493 when he was slain by Theodoric during a shared meal inside the imperial palace Honorius Ad Laurentum At The Laurel Grove. Theodoric struck Odoacer himself after their plan for followers to kill him went astray.
Odoacer introduced important changes to the administrative system of Italy including granting tax immunity to Liguria inhabitants for five years and issuing coins bearing legend S(enatus) C(onsulto).
