409

Year 409 was a common year starting on Friday of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Honorius and Theodosius. The denomination 409 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.
