Ubba
Ubba (Old Norse Ubbi) was a 9th-century Viking leader who died in 878. He was one of the commanders of the Great Heathen Army that invaded Anglo-Saxon England in the 860s. This army wasn’t a single force; it was a mix of warbands from Scandinavia, Ireland, and the Continent, and some troops may have come from Frisia. Some sources call Ubba a duke of the Frisians, suggesting he led Frisian troops as part of the alliance.
In 865 the Great Army overwintered in East Anglia, then moved to Northumbria and defeated its kings. In 869 the Vikings conquered East Anglia and killed its king, Edmund. Some later legends link Ubba to Edmund’s martyrdom, but contemporary records do not clearly connect them.
Ubba and Ivar the Boneless became famous as the archetypal Viking invaders and opponents of Christianity. Later stories tie Ubba to legends about Ragnar Lodbrok, but these connections are not reliable historical facts. Ubba’s exact origins are unclear: some accounts suggest a Frisian connection, while others keep him as a Scandinavian Viking.
After East Anglia fell, leadership of the Great Army passed to Bagsecg and Halfdan. Around 873 the army split: one group under Guthrum, Oscytel, and Anwend moved south against Wessex, while Halfdan settled in Northumbria. In 877–878 Guthrum and his men struck deep into Wessex. Another Viking force in Devon was said to be destroyed at Arx Cynuit in 878. A near-contemporary source says a brother of Ivar and Halfdan led that force, and some later writers identify this man as Ubba.
Towards the end of the 870s, King Alfred the Great fought back. The Vikings were finally defeated at Edington in 878, and Guthrum agreed to baptism and to rule East Anglia peacefully for a time. Guthrum later ruled as a Christian king until his death.
Many later tales try to link Ubba with Edmund’s death or with Ragnar Lodbrok. Medieval writers used such figures to explain the Viking presence in England, and Ubba became a symbol of Viking savagery in some stories. In modern fiction and media, Ubba often appears as a character inspired by these legends, sometimes with different names or details.
The exact details of Ubba’s life and death remain uncertain. What most historians agree on is that he was a major Viking commander during the mid-9th century, part of the Great Heathen Army that reshaped England and left a lasting mark in legend as well as history.
