Glycerius was not recognized by the Eastern Roman emperor Leo I, who instead nominated Julius Nepos as Emperor and sent him with an army to invade the Western Empire. Glycerius was without allies, because Gundobad had left to rule the Burgundians, and therefore was forced to abdicate on 24 June 474. He was appointed Bishop of Salona, which position he held until his death. He died some time after 474, possibly 480. He may have had a role in the assassination of Julius Nepos in 480.
