Agrippa Postumus (26 June 12 BC – 20 August AD 14), also referred to as
Postumus Agrippa, was a son of
Marcus Vipsanius Agrippa and
Julia the Elder. He was originally named
Marcus Vipsanius Agrippa Postumus in honor of his father, who died shortly before Postumus' birth. After the deaths of his older brothers,
Lucius (d. AD 2) and
Gaius Caesar (d. AD 4), Postumus was
adopted by his maternal grandfather, the
Roman emperor Augustus. In accordance with
Roman naming conventions, Postumus' name was changed to
Marcus Julius Caesar Agrippa Postumus. At the time Augustus considered Postumus as a potential successor, until Postumus' scandalous behavior led to his banishment from
Rome. This, in effect, though not in law, cancelled his adoption and virtually assured
Tiberius' position as Augustus' sole heir. Postumus was ultimately executed by his own guards shortly after Augustus' death in AD 14.
