__NOTOC__
The year '''509 BC''' was a year of the [[Roman calendar|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.
