NOTOC Year 171 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Crassus and Longinus (or, less frequently, '*year 583 *Ab urbe condita'''''). The denomination 171 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.
