[Priscus of Panium](/source/Priscus) (left) with the Roman [embassy](/source/Diplomatic_mission) at the court of [Attila the Hun](/source/Attila_the_Hun) Year **447** (**[CDXLVII](/source/Roman_numerals)**) was a [common year starting on Wednesday](/source/Common_year_starting_on_Wednesday) of the [Julian calendar](/source/Julian_calendar). At the time, it was known in the Roman Empire as the **Year of the Consulship of Calepius and [Ardabur](/source/Ardabur_(consul_447))** (or, less frequently, **year 1200 *[Ab urbe condita](/source/Ab_urbe_condita)***). The denomination 447 for this year has been used since the early medieval period, when the [Anno Domini](/source/Anno_Domini) [calendar era](/source/Calendar_era) became the prevalent method in Europe for naming years. ## Events ### By place #### Byzantium - [November 6](/source/November_6) – The [Walls of Constantinople](/source/Walls_of_Constantinople) are severely damaged by an earthquake, which destroys large parts of the structure, including 57 [towers](/source/Tower). The population is threatened by a plague. Emperor [Theodosius II](/source/Theodosius_II) orders [Constantine](/source/Constantine_(consul_457)), [praetorian prefect of the East](/source/Praetorian_prefecture_of_the_East), to supervise the repairs. He employs the city's *demoi* ("[Circus](/source/Hippodrome_of_Constantinople) factions") in the work, and rebuilds the walls within 60 days. - The [Huns](/source/Huns), led by [Attila](/source/Attila), cross the [Danube](/source/Danube), and invade the [Balkans](/source/Balkans) as far as [Thermopylae](/source/Thermopylae) (Greece). During the invasion, [Serdica](/source/Serdica) (modern [Sofia](/source/Sofia)) is destroyed. For disobeying the terms of the treaty made in [442](/source/AD_442), Attila triples his demand for [tribute](/source/Tribute) to 2,100 pounds (ca. 700 kg) of [gold](/source/Gold) per year; and the [ransom](/source/Ransom) for each Roman prisoner to 12 *[solidi](/source/Solidus)*. - Theodosius II sends an [embassy](/source/Diplomatic_mission) to Attila; [Priscus of Panium](/source/Priscus), envoy for the [Eastern Roman Empire](/source/Eastern_Roman_Empire). Priscus records one of the few eyewitness accounts of the Hun kingdom. - [Battle of the Utus](/source/Battle_of_the_Utus): Attila defeats the [Roman army](/source/Late_Roman_army) near the river [Utus](/source/Utus) (Vit, Bulgaria). The Huns are forced to abandon the siege of [Constantinople](/source/Constantinople). They march north and plunder the defenseless Balkan provinces (including [Thrace](/source/Thrace), [Scythia](/source/Scythia_Minor_(Roman_province)), [Moesia](/source/Moesia), [Dacia](/source/Roman_Dacia) and [Illyricum](/source/Illyricum_(Roman_province))). - Winter – Theodosius II chooses a policy to protect Constantinople against the Huns. He removes [Aspar](/source/Aspar) and [Areobindus](/source/Areobindus_(consul_434)) (*[magister militum](/source/Magister_militum)*) from their military commands.[1] #### Europe - [Vortigern](/source/Vortigern), [king of the Britons](/source/King_of_the_Britons), receives the [Saxon](/source/Anglo-Saxons) leaders [Hengist and Horsa](/source/Hengist_and_Horsa) "as friends" and grants the brothers the [Isle of Thanet](/source/Isle_of_Thanet), most easterly point of [Kent](/source/Kingdom_of_Kent) (England). ### By topic #### Arts and Sciences - The first entry in the *[Annales Cambriæ](/source/Annales_Cambriae)* refers to this year. #### Religion - [Germanus](/source/Germanus_of_Auxerre), [bishop of Auxerre](/source/Ancient_Diocese_of_Auxerre), makes his second visit to [Britain](/source/Roman_Britain). - The [Synod of Toledo](/source/Councils_of_Toledo) (Spain) tries to add the [filioque clause](/source/Filioque) to the [Nicene Creed](/source/Nicene_Creed). The [Eastern Orthodox Church](/source/Eastern_Orthodox_Church) refuses to go along with this idea. ## Deaths - [Areobindus](/source/Areobindus_(consul_434)), Roman general (*[magister militum](/source/Magister_militum)*) - [Juqu Mujian](/source/Juqu_Mujian), prince of the Chinese state [Northern Liang](/source/Northern_Liang) - [Secundinus](/source/Secundinus) (or Seachnaill), [patron saint](/source/Patron_saint) ## References 1. **[^](#cite_ref-1)** *The End of Empire* (p. 144).
