Map of the Eastern Hemisphere in 323 BC.
Year 323 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Longus and Cerretanus (or, less frequently, year 431 Ab urbe condita). The denomination 323 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.
