Olybrius is one of the least distinguished Emperors in Roman history. He reigned over the Western Roman Empire for only seven months, and for that whole time, he was little more than the puppet of the men who had put him on the throne, the general Ricimer and his nephew Gundobad.
Olybrius was of the Roman senatorial class, and by his marriage (to Placida, daughter of Emperor Valentinian III) a member of the Imperial House of Theodosius – the last of that House, in fact. He spent most of his reign distracted by religious matters while Ricimer and (after Ricimer’s death) Gundobad ruled in his name. He died of dropsy, and only three more Emperors followed him before the western empire died too.
