Agrippa died in 12 BC, and Tiberius was ordered by Augustus to divorce his wife

, of murdering him at Tiberius's orders. With Germanicus dead, Tiberius began elevating his own son Drusus to replace him as the Imperial successor. By this time Tiberius had left more of the day-to-day running of the Empire to
Lucius Aelius Sejanus.
Sejanus created an atmosphere of fear in Rome, controlling a network of informers and spies whose incentive to accuse others of treason was a share in the accused's property after their conviction and death. Treason trials became commonplace; few members of the Roman aristocracy were safe. The trials played up to Tiberius' growing paranoia, which made him more reliant on Sejanus, as well as allowing Sejanus to eliminate potential rivals. Victims of this reign of terror related to the imperial family included
Gaius Asinius Gallus Saloninus, second husband of Tiberius' first wife Vipsania, who had since died, and

Tiberius, perhaps sensitive to this ambition, rejected Sejanus's initial proposal to marry
Livilla, Germanicus' sister and the widow of Tiberius' son Drusus the Younger, who had since died, in AD 25, but later had withdrawn his objections so that, in AD 30, Sejanus was betrothed to
Julia Livia, daughter of Livilla and Drusus the Younger. Sejanus' family connection to the Imperial house was now imminent, and in AD 31 Sejanus held the Consulship with the emperor as his colleague, an honour Tiberius reserved only for heirs to the throne. When he was summoned to a meeting of the Senate later that year on 18 October AD 31, he probably expected to receive a share of the tribunician power. Instead, however, Tiberius' letter to the Senate, completely unexpectedly, requested the destruction of Sejanus and his faction. A purge followed, in which Sejanus and his most prominent supporters were killed. With Drusus dead and having had Germanicus' elder two sons
Nero and
Drusus convicted of treason and killed, along with their mother Agrippina, Tiberius appointed Caligula, Germanicus' youngest son, and

was later forced to commit suicide after being accused of adultery.
Rome's second Emperor died at the port town of Misenum on 16 March AD 37, at the age of 78 years, having reigned for 23 years. Suetonius writes that the Prefect of the
Praetorian Guard Naevius Sutorius Macro smothered Tiberius with a pillow to hasten Caligula's accession. According to Suetonius, he was known for his cruelty and debauchery through his perversion on the island of Capri where he forced young boys and girls into orgies. On one account when one of the boys complained, Tiberius had his legs broken.
Caligula
Although Augustus' succession plans were all but ruined due to the deaths of more than several family members, including many of his own descendants, in the end, Tiberius remained faithful to his predecessor's wishes that the next emperor would hail from the Julian side of the Imperial family. Thus, Tiberius was succeeded by Gaius Julius Caesar Augustus Germanicus, the sole-remaining son of his nephew and adopted son Germanicus. The new emperor was a great grandson of Augustus through his mother
Agrippina the Elder thus making him a Julian but he was also a Claudian through his father Germanicus being the son of

invasion of Britain in AD 43. He took a personal interest in the law, presided at public trials, and issued up to twenty edicts a day; however, he was seen as vulnerable throughout his rule, particularly by the nobility. Claudius was constantly forced to shore up his position—resulting in the deaths of many senators. Claudius also suffered tragic setbacks in his personal life. He married four times (to, in order,

In late AD 67 or early 68,

Gaul, rebelled against Nero's tax policies.
Lucius Virginius Rufus, the governor of superior Germany, was sent to put down the rebellion. To gain support, Vindex called on
Galba
Galba (; born Servius Sulpicius Galba; 24 December 3 BC – 15 January AD 69) was the sixth Roman emperor, ruling from AD 68 to 69. After his adoption by his stepmother, and before becoming emperor, he was known as Livius Ocella Sulpicius Ga ...

(in the
Iberian Peninsula), to become emperor. Virginius Rufus defeated Vindex's forces and Vindex committed suicide. Galba was declared a public enemy and his legion was confined in the city of Clunia.
Nero had regained the control of the empire militarily, but this opportunity was used by his enemies in Rome.
Nymphidius Sabinus, who desired to become emperor himself, bribed the Praetorian Guard to betray Nero. Sabinus was later murdered in favour of Galba.
Nero reportedly committed suicide with the help of his scribe
Epaphroditus. The Senate had been trying to preserve the dynastic bloodline by saving Nero's life, and were additionally reluctant to let someone who was not of the family become emperor; however, once he had committed suicide, and with Galba marching on the city, it had no choice but to declare him a public enemy posthumously. With his death, the reign of the Julio-Claudian dynasty came to an end. Chaos then ensued in the
Year of the Four Emperors.

Relationships among the rulers

The great-uncle/great-nephew blood relationship and/or adopted son relationship was commonly found among the rulers of the Julio-Claudian dynasty.
# Augustus was the great-nephew and posthumously adopted son of Julius Caesar; his mother Atia was the daughter of Caesar's sister Julia.
# Caligula was the great-nephew and adoptive grandson (via the adoption of his father Germanicus) of Tiberius; his father was the son of Tiberius' brother Drusus.
# Claudius was the great-nephew of Augustus, as well as the nephew of Tiberius (and the only Julio-Claudian who was not adopted); his mother Antonia was the daughter of Augustus' sister Octavia, and his father Drusus was the brother of Tiberius.
# Nero was the great-nephew and adopted son of Claudius; his mother Agrippina, in addition to being married to Claudius, was the daughter of Claudius' brother Germanicus.
The other recurring relationship between emperor and successor is that of stepfather/stepson, a relationship not by blood but by marriage:
# Tiberius was Augustus' stepson due to the latter's marriage to
Livia Drusilla. He and his brother
Drusus were Livia's sons through her previous marriage to
Tiberius Claudius Nero.
# Nero, biological son of
Gnaeus Domitius Ahenobarbus, became the stepson of his great-uncle Claudius when the emperor married his niece
Agrippina the Younger
Julia Agrippina (6 November AD 15 – 23 March AD 59), also referred to as Agrippina the Younger, was Roman empress from 49 to 54 AD, the fourth wife and niece of Emperor Claudius.
Agrippina was one of the most prominent women in the Julio-Claud ...
.
The uncle/nephew relationship is also prominent:
# Tiberius was Claudius's paternal uncle, being the older brother of Drusus, Claudius' father.
# Claudius was Caligula's paternal uncle, being the younger brother of Germanicus, Caligula's father.
# Caligula was Nero's maternal uncle, being the older brother of Agrippina the Younger, Nero's mother.
There were several instances of Emperors being father-in-law and son-in-law to each other:
#Tiberius, in addition to being Augustus' stepson and adopted son, was married to
Julia the Elder, daughter of Augustus.
#Nero, in addition to being Claudius' great-nephew, stepson and adopted son, was married to
Claudia Octavia, daughter of Claudius.
The following bullet points illustrate the lineage of Julio-Claudian emperors (adoptions included; emperors in bold):
*Augustus, adopted son of Julius Caesar
**Tiberius, adopted son of Augustus
***Germanicus, adopted son of Tiberius
****Caligula, son of Germanicus
**Drusus, stepson of Augustus
***Claudius, son of Drusus
****Nero, adopted son of Claudius
No Julio-Claudian emperor was a blood descendant of his immediate predecessor. Although Tiberius and Claudius had potential heirs (
Tiberius Gemellus, grandson of Tiberius through his son Drusus, and
Britannicus
Tiberius Claudius Caesar Britannicus (12 February AD 41 – 11 February AD 55), usually called Britannicus, was the son of Roman emperor Claudius and his third wife Valeria Messalina. For a time he was considered his father's heir, but that ...
, son of Claudius, respectively) available for the succession, both were, in turn, ultimately succeeded by their great-nephews Caligula and Nero, respectively.
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's ''
I, Claudius'' as a dangerous world where scheming family members were all too ready to murder the direct heirs so as to bring themselves, their own immediate families, or their lovers closer to the succession.
