Iulius Valerius Maiorianus was born in 420 and was a capable general of the Roman army and had several victories over the Franks and the Alemanni.
Following the deposition of ruler Avitus, Majorian was declared emperor by a Regent named Ricimer but this did not sit well with Emperor Leo who was based in Constantinople and saw Majorian as a usurper.
Following a battle with King Theodoric of the Visigoths and then forming an allegiance with him, he set out to join his navy fleet but the King of Vandals attacked destroying most ships and taking others.
Peace was made with the King of Vandals but Majorians reputation had been ruined and the soldiers mutinied led by Ricimer. Five days later Majorian died of either dysentery or physical violence.
