The Huns, taking advantage of the departure of the Goths, Quadi, et al., created a significant empire in 423 based in Hungary. In 453 they reached the height of their expansion under the well-known conqueror, Attila the Hun. The empire collapsed in 455, when the Huns were defeated by the neighbouring Germanic tribes (such as the Quadi, Gepidi and Sciri). The Gepidi (having lived to the east of the upper Tisza river since 260 CE) then moved into the eastern Carpathian Basin in 455. They ceased to exist in 567 when they were defeated by the Lombards and Avars. The Germanic Ostrogoths inhabited Pannonia, with Rome's consent, between 456 and 471.
