The 5th century

1,296 sourced entries across 100 documented years, grouped into 10 decades. A century here runs 1900–1999 rather than 1901–2000, so its decades sit inside it exactly; on the BC side the same rule puts 1–99 BC in the 1st century BC and 100 BC in the 2nd.

A few of the years

400January 9 – Emperor Arcadius gives his wife Aelia Eudoxia the official title of Augusta. She is able to wear the purple paludamentum and is depicted in Roman currency.
412Heraclianus, governor (Comes Africae), revolts against Honorius and proclaims himself Augustus. He interrupts the grain supply to Rome. Honorius condemns him and his supporters to death with an edict at Ravenna.
424April 22 – Flavius Anthemius Isidorus becomes the new Praetorian prefect of Illyricum, comprising most of Greece and Serbia, taking office at the capital, Sirmium (now Sremska Mitrovica in Serbia).
436End of the Burgundian Revolt of Gunther: Flavius Aetius, Roman general (magister militum), attempts to put an end to Burgundian raids in Gaul. He calls in Hun mercenaries under the command of Attila and his brother Bleda, which plunder Augusta Vangionum, killing some 20,000 Burgundians. The Kingdom of the Burgundians is destroyed; King Gunther and his family are killed (this epic disaster will later provide the source for the Nibelungenlied).
448Rechiar succeeds his father Rechila as king of the Suebi in Galicia (Northern Spain). He marries a daughter of the Visigoth king Theodoric I and converts to Catholicism.
460March 27 (night) – Swabians invade the Gallic city of Lugo. The governor is killed.
472July 11 – Anthemius, besieged in the part of Rome he controls until his troops are defeated, is caught while fleeing the city disguised as a supplicant in the Old St. Peter's Basilica (or at the church of Santa Maria in Trastevere), and later beheaded by Gundobad or Ricimer. Ricimer proclaims Olybrius emperor. Ricimer's nephew, the Burgundian general Gundobad, assumes command of the Western army and holds de facto power in the Empire.
484February 24 – King Huneric passes the Edict of 484, a law banning Catholicism within the Vandal Kingdom. A few weeks later, King Huneric removes Catholic bishops from their offices and banishes some to Corsica. A few are martyred, including former proconsul Victorian along with Frumentius and other merchants. They are killed at Hadrumetum after refusing to become Arians.
