Germanicus was a popular imperial Roman general. He stifled a rebellion in the west on the death of Augustus in AD 14. Though urged to take imperial power, he deferred to Tiberius. In the East, he came into conflict with Gnaeus Calpurnius Piso, governor of Syria. His death may have been due to poisoning ordered by Piso, though Tiberius was also suspected. He was immensely popular among the citizens of Rome.
