The Julio-Claudian dynasty refers to the first five Roman Emperors: Augustus, Tiberius, Caligula, Claudius, and Nero. They ruled the Roman Empire from 27 BC to AD 68, when the last of the line, Nero, committed suicide. These five rulers were linked through marriage and adoption into the familial gens Julia and gens Claudia. Julius Caesar is sometimes inaccurately seen as its founder, although he was not an emperor and had no Claudian connections; Augustus is the more widely accepted founder.

Dynastic relations


This dynasty is known as the Julio-Claudians because its members were drawn from two of the patrician gentes of Ancient Rome, the Julii and the Claudii. Its founder, Augustus, was a Julian through adoption by his great-uncle, Julius Caesar.

Tiberius was born a Claudian but, like Augustus before him, became a Julian upon his adoption.

Caligula, however, had both Julian and Claudian ancestry being a Julio-Claudian, and was also a direct blood great-grandson of Augustus.

Claudius was a Claudian, though he was descended from the Julian family through his maternal grandmother Octavia Minor—sister of Augustus—whose own maternal grandmother was Julia, Caesar's sister.

Like Caligula before him, Nero also shared Julian and Claudian ancestry. Nero, again like Caligula, was a descendant of Augustus, a great-great-grandson.

The rise and fall of the Julio-Claudians


All responsable rulers, acknowledging that they are not immortal, try to choose a worthy political heir in a most careful fashion, and Augustus was no different. Lacking any male child, he married his only natural daughter Julia to Marcus Claudius Marcellus, his nephew by his own sister Octavia Minor. However, Marcellus died of food poisoning in 23 BC. Reports of later historians that this poisoning, and other later deaths, were organized by Livia Drusilla, wife of Augustus, are unproven, and inconclusive at best.

Augustus then married his widowed daughter to his loyal friend, Marcus Vipsanius Agrippa. This marriage produced five children, three sons and two daughters: Gaius Caesar, Lucius Caesar, Vipsania Julia, Agrippina, and Postumus Agrippa. All male children were potential heirs, especially the first two children, who were adopted by Augustus. Augustus also showed great favor towards Livia's children from her first marriage, Nero Claudius Drusus Germanicus and his brother Tiberius Claudius Nero, successful military leaders who had fought against the barbaric Germanic tribes.

Agrippa died in 12 BC, and Tiberius was ordered by Augustus to divorce his beloved wife Vipsania Agrippina and to marry the twice widowed Julia. Drusus, the brother of Tiberius died in 9 BC, as he fell down a horse. Tiberius shared in Augustus' tribune powers, but shortly thereafter in 6 BC, he departed for Rhodes, into voluntary exile. After the early deaths of both Gaius in 4 AD and Lucius in 2 AD, Augustus banished Postums for reasons unknown to us around AD 6 or 7 to the small island of Planasia. Tiberius was recalled to Rome and was officially adopted by Augustus. He was the only remaining reasonable choice.

On 19 August 14 AD, Augustus died. In his will Postumus Agrippa and Tiberius were named as co-heirs. However, Postumus was quickly executed. Who ordered his death is unclear, but the way was clear for Tiberius to assume the same powers that his stepfather had had.

Great-nephews


It is interesting how commonly the blood relationship of great-uncle /great-nephew is found between the rulers of Julio-Claudian dynasty.
  • 1) Augustus was the great-nephew of Julius Caesar (and his adopted son).
  • 2) Caligula was the great-nephew of Tiberius (and his adopted son)
  • 3) Claudius was the great-nephew of Augustus.
  • 4) Nero was the great-nephew of Claudius (and his adopted son).
The other recurring relationship between emperor and successor is that of stepfather/stepson, a relationship not by blood but by marriage:
  • 1) Tiberius was Augustus's stepson
  • 2) Nero, as well as being Claudius' great-nephew, was also his stepson (his mother Agrippina being Claudius' niece, and also Claudius' fourth wife). The uncle/nephew relationship also is prominent: Tiberius was Claudius' uncle, and Claudius was Caligula's uncle.

No Julio-Claudian emperor was a blood descendent of his immediate predecessor. Both Tiberius and Claudius had male direct descendants (Tiberius' grandson Tiberius Gemellus, Claudius' son Britannicus) available for the succession, but their great-nephews were preferred.

The fact that ordinary father-son (or grandfather-grandson) succession did not occur has contributed to the image of the Julio-Claudian court presented in Robert Graves' I, Claudius, a dangerous world where scheming family members were all too ready to murder the obvious, direct heirs so as to bring themselves, their own immediate families, or their lovers closer to the succession.
