Ubba

Ubba was a ninth-century Viking, and one of the commanders of the Great Army that invaded Anglo-Saxon England in the 860s. The Great Army appears to have been a coalition of warbands drawn from Scandinavia, Ireland, the Irish Sea region, and the Continent. There is reason to suspect that a proportion of the Viking forces specifically originated in Frisia, where some Viking commanders are known to have held fiefdoms on behalf of the Franks. Some sources describe Ubba as dux of the Frisians, which could be evidence that he also associated with a Frisian benefice.
