The year 509 BC was a year of the pre-Julian Roman calendar. In the Roman Republic it was known as the Year of the Consulship of Brutus and Collatinus (or, less frequently, year 245 Ab urbe condita). The denomination 509 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
