Year 453 (CDLIII) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Opilio and Vincomalus (or, less frequently, year 1206 Ab urbe condita). The denomination 453 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.
- Attila the Hun is found dead in bed after a wedding feast with the Goth princess Ildica. He dies of a nosebleed at his Hungarian stronghold, drowning in his own blood at age 47 (approximate). The Huns celebrate a strava (lamentation) over his burial place with great feasting. Attila has intended to renew his attacks on Constantinople and reclaims the tribute which emperor Marcian had stopped in late 450. The Hunnic Empire is divided between his sons Ellac (appointed successor), Dengizich and Ernakh. They fight over his legacy, and establish their kingdoms north of the Black Sea (Ukraine) supported by vassal states.
