Year 211 (CCXI) was a common year starting on Tuesday of the Julian calendar. At the time, in the Roman Empire it was known as the Year of the Consulship of Terentius and Bassus (or, less frequently, year 964 Ab urbe condita). The denomination 211 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.
