The Heruli were one of the smaller Germanic peoples of Late Antiquity, known from records in the third to sixth centuries AD. The best recorded group of Heruli established a kingdom north of the Middle Danube, probably in or near present day Lower Austria, where the kingdom of the Rugii also existed at that time. These two kingdoms were among several which precipitated out of the Hun empire, following the death of Attila in 453 and the Battle of Nedao in 454. After the conquest of this Heruli kingdom by the Lombards, which happened in the period 493-511, splinter groups moved to Scandinavia and the region near present day Belgrade, which was at that time under Eastern Roman control.
