Tiberius Claudius Drusus's grandfather was Marcus Plautius Silvanus and his great-grandmother was Urgulania. Urgulania is presumed to have helped her friend Livia, the future emperor's grandmother and the wife of the emperor Augustus, to arrange the marriage of Claudius and Plautia Urgulanilla when Claudius was around 18. Claudius married Plautia Urgulanilla sometime between 9 and 12 AD. Tiberius Claudius Drusus was born soon after the marriage, decades before his father became emperor. Throughout his life, the emperor was his relative Tiberius, son of Livia.
Life
Some five months after his daughter Claudia Julia was born, Claudius divorced Plautia on suspicion of adultery and complicity in the murder of Apronia, her brother's wife, who had been pushed from a window. The divorce may have been as early as 20 to as late as 27 AD. Claudius disowned Claudia Julia by exposing her on Urgulanilla's doorstep, believing her to be fathered by a freedman of his, but he did not dispute the paternity of his son Claudius Drusus, leaving the boy Claudius's only son at the time. A marble statue of Claudius Drusus was installed in the Sebasteion of Aphrodisias, an augusteum temple dedicated to the cult of the divine emperors and their family; its inscribed base was uncovered during archaeological excavations there in the late twentieth century. Claudius Drusus was betrothed to Aelia Junilla, the only daughter of Lucius Aelius Sejanus, the commander of the Praetorian Guard. In 20 AD Sejanus was reaching the height of his power, and the birth of his daughter offered an opportunity to connect his own family with the imperial Julio-Claudian dynasty. This betrothal filled Sejanus, then just a prefect, with unfulfilled hopes. The Roman historian Tacitus wrote that the people were not satisfied with this match as they were with the betrothal of Claudius Drusus's cousin, Nero Caesar, son of the popular general Germanicus Julius Caesar. Probably it was felt the nobility of the family was to be polluted; Sejanus was not of senatorial rank and his appointment as a praetor in 20 AD was an unprecedented novelty. Claudius Drusus was ultimately never married to Aelia Junilla, who may have only been born in the year of their betrothal. According to Tacitus:
Coinage
Probably in honour of the occasion of his betrothal to Aelia Junilla, a issue of coins is known to have been minted at Myrina in Aeolis, on the coast of Asia Minor. Myrina was of little importance at the time, and had comparatively little involvement in the imperial cult. However, in 17 AD the region suffered a major earthquake, and Myrina was one of twelve cities to receive funds for reconstruction from the Fiscus, the imperial treasury, as well as five years' tax remission from the Roman Senate. It is therefore likely that the coins, of which five examples are known to exist, were issued at a time of substantial gratitude towards Tiberius. The obverse of the bronze coins shows a draped bust of Claudius Drusus facing to the right with the legend written clockwise in. On the reverse is a wreathed head of Apollo, together with a lyre and the name of the Myrina mint, written anti-clockwise:.
Death
The year of Claudius Drusus's death is not precisely known. The Roman historian Suetonius's account suggests he died in 20 AD, but Tacitus's Annales suggests he was still alive in 23 AD, when, according to Tacitus the emperor Tiberius's son Drusus the Younger said of Sejanus in disgust "the grandsons of us Drususes will be his grandsons too". This suggests that Claudius Drusus was still due to marry Sejanus's daughter. Subsequently, it was suspected that Claudius Drusus had been murdered by Sejanus, but Suetonius did not believe that. Instead Suetonius said he had choked to death on a pear he had thrown into the air. According to him, Claudius Drusus;
