Battle of Pydna (Greece)
Year 168 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Macedonicus and Crassus (or, less frequently, year 586 Ab urbe condita). The denomination 168 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.
