Tiberius' son, Drusus Caesar, d. 23, called Drusus Junior, served in the provinces Pannonia ( 15) and in Illyricum ( 17-20). In 22 he was made tribune. Meanwhile, Sejanus, Tiberius' minister, had become jealous of Drusus' power and tried to turn Tiberius against him. In order to move himself into the position of succeeding Tiberius, Drusus had an affair with Drusus' wife, and Drusus probably was poisoned by Sejanus, or by his wife under Sejanus' influence.
