465 BC

Year 465 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Vibulanus and Barbatus (or, less frequently, year 289 Ab urbe condita). The denomination 465 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.
