The historians Tacitus and Cassius Dio depict an overweening, even domineering dowager, ready to interfere in Tiberius’ decisions. The most notable instances were the case of Urgulania (grandmother of Claudius's first wife Plautia Urgulanilla), a woman who correctly assumed that her friendship with the empress placed her above the law; and Munatia Plancina, suspected of murdering Germanicus and saved at Livia's entreaty. (Plancina committed suicide in AD 33 after being accused again of murder after Livia's death.) A notice from AD 22 records that Julia Augusta (Livia) dedicated a statue to Augustus in the center of Rome, placing her own name even before that of Tiberius.
