After the death of Marcellus in 23 BC, Augustus married his daughter to Agrippa. This union produced five children, three sons and two daughters: Gaius Caesar, Lucius Caesar, Vipsania Julia, Agrippina the Elder, and Postumus Agrippa, so named because he was born after Marcus Agrippa died. Shortly after the Second Settlement, Agrippa was granted a five-year term of administering the eastern half of the Empire with the "imperium" of a proconsul and the same "tribunicia potestas" granted to Augustus (although not trumping Augustus's authority), his seat of governance stationed at Samos in the eastern Aegean. This granting of power showed Augustus's favor for Agrippa, but it was also a measure to please members of his Caesarian party by allowing one of their members to share a considerable amount of power with him.
