174 BC

Year 174 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Paullulus and Scaevola (or, less frequently, year 580 Ab urbe condita). The denomination 174 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.
