During much his reign, the young Emperor was overshadowed by his mother and regent, Agrippina the Younger, who oversaw the administration of the empire, military movements against two other pretenders to the principate (Domitius Corbulo and Publius Petronius). This merely left Tacitus as a figurehead, used by his mother as a way to legitimise her control of the nation whilst he remained under house arrest during his twelve months "in power". This power structure in Rome left many proconsuls/governors unimpressed with the situation in the capital, with some going as far as refusing to accept Tactitus as Caesar, only to have the provinces they governed levied with high taxes.
Following the defeat of the imperial army during the Battle of Saena on July 5, 795, the senate abandoned their support for Tacitus and his mother, and instead transferred it over to the victorious Domitius Corbulo who was preparing to march on Rome. On the night of July 7, as Corbulo was closing in on the capital, Agrippina, instead of handing herself over to the victor, smothered her son in his sleep, and proceeded to commit suicide by slicing her own throat.
