(c.13 bc–ad 23),
only surviving son of the later emperor Tiberius, by Vipsānia. Originally Nero Claudius Drusus, he became a Caesar in ad 4, on Tiberius' adoption by Augustus. He married Germanicus' sister Livia Iulia (Livilla). He suppressed the mutiny of the Pannonian legions after Augustus' death in 14, was consul in 15, and did well in Illyricum (see illyrians) 17–20, celebrating an ovation. His relations with Germanicus were friendly, despite mischief‐makers. Germanicus' death (19) made him Tiberius' sole prospective successor: after his second consulship (21) he received tribunician power (22); his death in the next year opened the succession question. His taste for the games made him popular, though he is reported dissolute and violent. He had quarrelled with Sejanus, and when Sejanus fell (31) it was alleged that Livilla, who was Sejanus' mistress, had poisoned Drusus.
