541

Year 541 (DXLI) was a common year starting on Tuesday of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Basilius without colleague (or, less frequently, year 1294 Ab urbe condita). Basilius was the last person to be officially appointed Roman consul, since after this year, the office was permanently merged with the office of Roman/Byzantine emperor. Thus, from the next year forward, the consular year dating was abandoned. The denomination 541 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.
