AD 411



Year 411 (CDXI) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Theodosius without colleague (or, less frequently, year 1164 Ab urbe condita). The denomination 411 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.
