Agrippa Postumus father Augustus
Name
He was initially named "Marcus Agrippa" in honor of his father, who died shortly before his birth, for which reason the surname Postumus was added. After the death of his older brothers, Lucius and Gaius Caesar, Postumus was adopted by his maternal grandfather, Roman Emperor Augustus. A lex curiata ratified his adoption, from which Postumus assumed the filiation Augusti f., meaning "son of Augustus". Postumus was then legally the son of Augustus, as well as his biological grandson. As a consequence, Postumus was adopted into the Julia gens, and he took the name "Julius Caesar" as a result. His name was changed to Agrippa Julius Caesar.Adoption
At first, Augustus opted not to adopt Postumus so that Agrippa would have at least one son to carry on his family name. However, the untimely deaths of principes Lucius (d. AD 2) and Gaius (d. AD 4) forced Augustus to adopt Postumus, his only remaining biological grandson, and Tiberius, Augustus' eldest stepson from his third wife, Livia on 26 June AD 4 to secure the succession. He agreed to adopt Tiberius on the condition that Tiberius first adopt Germanicus. Upon his adoption into the Julii Caesares, Postumus assumed the name "Marcus Julius Caesar Agrippa Postumus". Following the adoptions of AD 4, in the event of Augustus' death, the title of princeps would pass first to Tiberius and then from Tiberius to Germanicus.It was not intended that Postumus receive the emperorship; instead, he was meant to be the heir to Augustus' bloodline. Postumus would receive Augustus' name, property, and bloodline, but not the title of princeps. Indeed, Postumus was not given any special schooling or treatment following his adoption. In AD 5, he received the toga virilis at the age of 17, and his name was added to the list of aristocratic youth eligible for training as military officers. This differed greatly from the honors received by his brothers, who were both conducted into the Forum by Augustus himself to commemorate their adoptions, given the title Princeps Iuventutis ("Leader of the Youth"), and promised the consulship five years in advance, to be held when they reached nineteen.
