Year 210 (CCX) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Faustinus and Rufinus (or, less frequently, year 963 Ab urbe condita). The denomination 210 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.
