He married Vipsania, the daughter of [[Marcus Vipsanius Agrippa]], Augustus' greatest general who defeated [[Mark Antony]] at the [[Battle of Actium]]. He had one son with Vipsania. Agrippa was also the husband of Tiberius' stepsister Julia, although he was much older. They had 3 sons together. When Agrippa died, Tiberius and Julia were forced by their parents to marry each other, even though it meant that Tiberius had to leave Vipsania. Although the marriage was reportedly peaceful at first the death of their young son Tiberillus caused the marriage to turn cold. Julia refused to acknowledge Tiberius as her equal and very soon she began petitioning to her father for a divorce. When Augustus refused, Tiberius and Julia separated. Tiberius left for Rhodes and Julia allied herself with [[Iullus Antonius]], the son of Mark Antony who allegedly became her lover. Julia was later exiled and Iullus executed, both for adultery and treason. | He married Vipsania, the daughter of [[Marcus Vipsanius Agrippa]], Augustus' greatest general who defeated [[Mark Antony]] at the [[Battle of Actium]].
