345 BC

Year 345 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Dorsuo and Camerinus (or, less frequently, year 409 Ab urbe condita). The denomination 345 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.

The Athenian statesman Demosthenes is among those who recommend this stance in his oration On the Peace.
