Overview
Lucius Caesar (17 BC – 20 August 2 AD) was a grandson of Augustus, the first Roman emperor. The son of Marcus Vipsanius Agrippa and Julia the Elder, Augustus' only daughter, Lucius was adopted by his grandfather along with his older brother, Gaius Caesar. As the emperor's adopted sons and joint-heirs to the Roman Empire, Lucius and Gaius had promising political and military careers. However, Lucius died of a sudden illness on 20 August 2 AD, in Massilia, Gaul, while traveling to meet the Roman army in Hispania. His brother Gaius also died at a relatively young age on 21 February 4 AD. The untimely loss of both heirs compelled Augustus to redraw the line of succession by adopting Lucius' younger brother, Agrippa Postumus as well as his stepson, Tiberius on 26 June 4 AD.
Background
Lucius' father Marcus Vipsanius Agrippa was an early supporter of Augustus (then "Octavius") during the Final War of the Roman Republic that ensued as a result of the assassination of Julius Caesar in 44 BC. He was a key general in Augustus' armies, commanding troops in pivotal battles against Mark Antony and Sextus Pompeius. From early in the emperor's reign, Agrippa was trusted to handle affairs in the eastern provinces and was even given the signet ring of Augustus, who was seemingly on his deathbed in 23 BC, a sign that he would become princeps were Augustus to die. It is probable that he was to rule until the emperor's nephew, Marcus Claudius Marcellus, came of age. However, Marcellus died of an illness that had spread throughout the city of Rome that year.
With Marcellus gone, Augustus arranged for the marriage of Agrippa to his daughter Julia the Elder, who was previously the wife of Marcellus. Agrippa was given tribunicia potestas ("the tribunician power") in 18 BC, a power that only the emperor and his immediate heir could hope to attain. The tribunician power allowed him to control the Senate, and it was first given to Julius Caesar. Agrippa acted as tribune in the Senate to pass important legislation and, though he lacked some of the emperor's power and authority, he was approaching the position of co-regent.
Early life and family
Lucius was born in Rome in 17 BC to Marcus Vipsanius Agrippa and Julia. He was part of the imperial family of Augustus, known as the Julio-Claudian dynasty, and was related to all the Julio-Claudian emperors. On his mother's side, he was the second oldest grandson of emperor Augustus after his brother Gaius.
