Аварский каганат
The Romans pulled out of the Hungarian plains in the 5th century AD to be succeeded by the Huns after fierce warfare. Upon the fragmentation of the Huns that resulted from the death of Attila the Hun, Germanic tribes (such as the Lombards) and the Avars occupied the area during the second Age of Migrations. The Avar Khaganate dominated Pannonia between the 6th and 9th centuries.
