401



Year 401 (CDI) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Vincentius and Fravitus (or, less frequently, year 1154 Ab urbe condita). The denomination 401 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.

Roman Empire

 * Emperor Arcadius sends many gifts to the Hunnish chieftain Uldin, in appreciation of his victory over the Goths and Gainas. Arcadius then allies himself with the Huns.
 * Piracy is committed by slave-traders from Galatia (Anatolia), along the coasts of Africa.

 * Stilicho, Roman general (magister militum), leads his army in an extensive campaign against the Vandals in Rhaetia (Switzerland).

 * November 18 – The Visigoths, led by king Alaric I, cross the Alps and invade northern Italy.
 * Emperor Honorius begins to use the city of Ravenna as a temporary center for certain administrative and military functions. The city is chosen because of its proximity to the bulk of the Western Roman army and due to the fact that its relative poverty makes it a less tempting target for barbarian invaders than cities such as Rome or Milan. This event is often misinterpreted as the establishment of Ravenna as a capital. In reality, the capital of the Western Roman Empire was not truly established at Ravenna until 408.
