According to Herwig Wolfram, following Jordanes, the Ostrogoths had a huge kingdom north of the Black Sea in the 4th century,[REF] which the Huns overwhelmed in the time of the Gothic king Ermanaric (or Hermanric; i.e. "king of noblemen"[REF]) when the Huns migrated to the Ukrainian steppe.
The Ostrogoths became vassals of the Huns until the death of Attila, when they revolted and regained independence.
