The Roman Senate (Latin: Senātus Rōmānus) was a governing and advisory assembly in ancient Rome. It was one of the most enduring institutions in Roman history, being established in the first days of the city of Rome (traditionally founded in 753 BC). It survived the overthrow of the Roman monarchy in 509 BC; the fall of the Roman Republic in the 1st century BC; the division of the Roman Empire in AD 395; and the fall of the Western Roman Empire in 476; Justinian's attempted reconquest of the west in the 6th century, and lasted well into the Eastern Roman Empire's history.
