Year 251 (CCLI) was a common year starting on Wednesday of the Julian calendar. At the time, in the Roman Empire, it was known as the Year of the Consulship of Traianus and Etruscus (or, less frequently, year 1004 Ab urbe condita). The denomination 251 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.
