Pannonia
a large extent of country in Europe, bounded on the N. by the Danube, S. by Illyricum and Mœsia, E. by the Danube, and W. by Noricum, inhabited by Celtic tribes and including the parts now known as Hungary and the Republic of Austria. It was attacked by the Romans, under Octovianus, 35 B. C., and made a Roman province by Tiberius in 8. It was ceded to the Huns by Theodosius II. about 447, came into the hands of the Ostrogoths at the death of Attila in 453, and to the Longobardi (527-565), from whom it passed to the Avari in 568. The Ungri, or Hungarians, settled here in 889; and from them a large part of Pannonia received the name of Hungary.
