Livia Drusilla (30 January 59 BC – . AD 29) was Roman empress from 27 BC to AD 14 as the wife of Augustus, the first Roman emperor. She was known as Julia Augusta after her formal adoption into the Julia gens in AD 14. Livia was the daughter of the senator Marcus Livius Drusus Claudianus and his wife Alfidia. She married Tiberius Claudius Nero around 43 BC, and they had two sons, Tiberius and Drusus. In 38 BC, she divorced Tiberius Claudius Nero and married the political leader Octavian. The Senate granted Octavian the title Augustus in 27 BC, effectively making him emperor.
