By the 5th century, lacking the wealth needed to pay and train a professional army, the Western Roman Empire's military strength was almost entirely reliant on "foederati" units. In 451, Attila the Hun was defeated only with help of the "foederati", who included the Visigoths, Alans and Saxons. The "foederati" would deliver the fatal blow to the dying nominal Western Roman Empire in 476, when their commander, Odoacer, deposed the usurping Western Emperor Romulus Augustulus and sent the imperial insignia back to Constantinople with the Senate's request for the 81-year-old west-east subdivision of the empire to be abolished. Even before the eventual fall of the Western Roman Empire in 476, several kingdoms with the status of "foederati" had managed to gain a full independence that was formally recognised by the Western Roman Empire, such as the Vandals in the peace treaty concluded in 442 between their king, Genseric, and Valentinian III and the Visigoths through the peace treaty concluded in 475 between their king Euric and Julius Nepos.
