who succeeded him?
Marcus Agrippa
Augustus
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.

Augustus [SEP] Death and succession
He took the consulship in 5 and 2 BC so that he could personally usher them into their political careers, and they were nominated for the consulships of AD 1 and 4. Augustus also showed favor to his stepsons, Livia's children from her first marriage Nero Claudius Drusus Germanicus (henceforth referred to as Drusus) and Tiberius Claudius (henceforth Tiberius), granting them military commands and public office, though seeming to favor Drusus. After Agrippa died in 12 BC, Tiberius was ordered to divorce his own wife Vipsania Agrippina and marry Agrippa's widow, Augustus's daughter Julia—as soon as a period of mourning for Agrippa had ended.
