In the beginning of the 4th century, a large group of Rugii settled at the upper Tisza in ancient Pannonia, in what is now modern Hungary. They were later attacked by the Huns but took part in Attila's campaigns in 451, but at his death they rebelled and created under Flaccitheus a kingdom of their own in Rugiland, a region presently part of lower Austria (ancient Noricum), north of the Danube. After Flaccitheus's death, the Rugii of Rugiland were led by king Feletheus, also called Feva, and his wife Gisa. Yet other Rugii had already become foederati of Odoacer, who was to become the first Germanic king of Italy. By 482 the Rugii had converted to Arianism. Feletheus' Rugii were utterly defeated by Odoacer in 487; many came into captivity and were carried to Italy, and subsequently, Rugiland was settled by the Lombards. Records of this era are made by Procopius, Jordanes and others.
