Flaccitheus

Flaccitheus (died c. 475) was the founder of the Kingdom of the Rugii.

Biography
Little is known about Flaccitheus, but he is mentioned in the work Vita Sancti Severini by Eugippius. After the Battle of Nedao in 454, the Rugii had settled on the north bank of the Danube. During the subsequent breakdown of Roman order in Noricum, the Rugii had exploited the situation to consolidate their power. By 467, Flaccitheus had established the Kingdom of the Rugii. He was in frequent conflict with the Ostrogoths, and although an Arian Christian, a close confidant of Severinus of Noricum. Flaccitheus died probably around 475, after which he was succeeded by his son Feletheus.
