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.
Eparchius Avitus was a member of the Gallo-Roman aristocracy of the empire in his day. He was a strong proponent of keeping Gaul in the empire, even holding his coronation in Toulouse. However, these views were unpopular with the Roman establishment, or rather, what remained of it after the city was sacked by the Vandals earlier that year.
However, he allowed the Vandals to take Hispania, and along with his appointment of other Gallo-Romans to important roles in his administration, this made him immensely unpopular, and he was deposed as Emperor after little more than a year on the throne.
One of the least successful Enely 276 without the consent of the Senate, and eventually died after losing a battle against rival Imperial claimant (and his eventual successor) Probus – he was, in fact, assassinated by his own troops.
Florianus had little basis for his claim to the throne – he was allegedly the half-brother of the previous Emperor, Tacitus – and little experience at political or military leadership – as Probus’ defeat of Florianus’ larger army clearly showed. In the end, he was little more than a blip in Roman history, albeit an indicator of an Empire in decay.
The sixth and final ruler of the Julio-Claudian dynasty, Nero was the grand-nephew of his predecessor, the Emperor Claudius and the nephew of Caligula, Claudius’ predecessor. He would become legendary for his cruelty, although most of the accounts attesting to it are from contemporaries who disliked him, and may have been exaggerated. Nero was only 17 when he ascended to the throne – it was only because both these Emperors died without issue that he even got that close to power. If either of the two had had a son, Nero would today be a footnote.
Instead, he would reign for 13 years, being the Emperor during the great fire of Rome in 64 CE (history records that Nero was instrumental in the rebuilding of Rome afterwards – the business about the fiddling seems to have been a rumour spread by his political enemies), and the famed revolts of Britannia (led by Boudicca) and Judea (which ended in the destruction of the Temple in Jerusalem, and the beginnings of the Jewish Diaspora). Upon his death in 68 CE, (also without issue,) Nero threw the Empire into the chaos and civil war of what became known as the Year of the Four Emperors.
Looking at the history of the last three Julio-Claudian Emperors, one can only conclude that for a people so infamous for their orgies, the Romans must have known a thing or two about birth control.
Shakespeare’s version might be better known, but the best historical account of the death of Big Julie was written by imperial biographer (and obsequious toady) Seutonius. It is from Suetonius that we have Caesar’s famous last words (asking Brutus ‘even you, my child?’, which Shakespeare rendered as ‘et tu, Brute?’) – although curiously, Seutonius himself reports those words as claimed by others, and for himself believes that Caesar said nothing.
This is somewhat hard to believe, given that Seutonius also recounts that Caesar was attacked by 60 or more men, and received a total of 23 stab wounds from his assailants – it appears that the proximate cause of death was loss of blood. (Fun fact: Caesar’s autopsy report is the earliest one to have survived to the present day.) In a larger sense, the cause of the death of Gaius Julius Caesar was political ambition – his own, and that of others.
