Although he was born to Marcus Vipsanius Agrippa and Julia, Augustus' only daughter, Gaius and his younger brother, Lucius Caesar, were raised by their grandfather as his adopted sons and joint-heirs to the empire. In 4 AD, following the deaths of Gaius and Lucius, Augustus adopted his stepson, Tiberius, as well as his sole-surviving grandson, Agrippa Postumus. 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. ./cache/en-wikipedia-org-8935.html ./txt/en-wikipedia-org-8935.txt
