 In the beginning of the 4th century, large parts of the Rugii moved southwards and 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.
