Ivar the Boneless

Ivar the Boneless is perhaps the most enigmatic of Ragnar’s sons. His epithet “Boneless” has been subject to various interpretations, ranging from a physical condition like osteogenesis imperfecta, which could have rendered his bones fragile, to symbolic meanings related to his cunning or magical abilities.

Ivar is often credited as the leader of the Great Heathen Army that invaded the Anglo-Saxon kingdoms of England in 865. Under his leadership, the army achieved significant victories, including the capture of York. Ivar’s strategic brilliance and ruthless tactics are well-documented, and he is portrayed as a master of psychological warfare.

After establishing a base in England, Ivar is said to have turned his attention to Ireland, where he became a king and founded the Norse kingdom of Dublin. His death is shrouded in mystery, with some sources suggesting he died peacefully in England.

Bjorn Ironside

Bjorn Ironside is renowned for his raids in France and the Mediterranean. According to legend, he was a fearsome warrior and an adept sailor who led expeditions that pillaged parts of Italy and Spain.

One of the most famous tales about Bjorn involves his cunning siege of Luna (believed to be mistaken for Rome), where he feigned death to gain entry into the city’s church before his men plundered it. Bjorn’s legacy extends beyond his raids; he is considered a founder of the Munsö dynasty, which ruled over parts of Sweden.

Unlike Ivar, Bjorn’s historical footprint in the Nordic regions is more pronounced, with many believing he settled down and ruled in Sweden after his raiding years.

Sigurd Snake-in-the-Eye

Sigurd Snake-in-the-Eye was named for the distinctive mark in his eye, described as being shaped like a snake or dragon.

Sigurd’s historical actions are less documented than those of Ivar or Bjorn, but he is often associated with the settlement and governance of parts of Denmark. He is said to have ruled over Zealand, Scania, Halland, Viken, and parts of Uppland.

His legacy is also tied to his lineage, as he is believed to have continued Ragnar’s line through his descendants, who played significant roles in Scandinavian history.

Famed for being the son of Ragnar Lodbrok, Sigurd Snake-in-the-Eye was said to have been born with the image of the ouroboros, a snake or dragon eating its own tail, in his eye. This mark was considered a sign of great destiny. Image: A 17th century engraving of Sigurd.


Hvitserk, whose name means “White Shirt” in Old Norse, is perhaps the least documented of Ragnar’s sons in historical texts.

His deeds and exploits are inconsistently reported, with some sagas suggesting he participated in the Great Heathen Army’s campaigns alongside Ivar.

One tale recounts Hvitserk’s tragic end through self-immolation, offered to Odin in atonement for a mistake, though the accuracy of this story is debated. Hvitserk’s historical presence is elusive, overshadowed by his more famous brothers, yet he remains a figure of fascination in Viking lore.


Ubbe is often identified with Ubba, a commander in the Great Heathen Army, though the historical records linking him directly to Ragnar as a son are sparse.

His contributions to the Viking invasions of England are significant, with his leadership and martial prowess frequently highlighted in accounts of the period. He is credited with playing a key role in the army’s victories and the subsequent Viking settlement in England.

The exact details of Ubbe’s life and death are murky, with some accounts suggesting he died in battle against the West Saxons.

Who were the wives of Ragnar Lodbrok?

According to the myths, Herrauðr, Earl of Götaland and Ragnar’s vassal, had a daughter called Þóra Borgarhjǫrtr. Þóra (Thora) was known for her beauty. In one account, she was given a lindworm, which later surrounded her tower, threatening all but her servants. During a feast, Herrauðr vowed Thora’s hand to whoever killed the beast.

Ragnar, upon learning this, ventured to Västergötland in tar-and-sand-coated clothes, armed with a spear. He confronted and killed the serpent, shielding himself from its poison. Having slain the beast and won Þóra’s hand, Ragnar married her and embarked on liberating his kingdom, showcasing his bravery and strategic prowess.

Before Thora’s death, she and Ragnar had sons Eric and Agnar. Ragnar then remarried Aslaug, the daughter of King Sigurd Ring and Brynhildr. From that marriage came forth four more sons: Ivar the Boneless, Ubba, Hvitserk, and Sigurd Snake-in-the-Eye.

How did Ragnar’s sons Eric and Agnar die?

Ragnar Lodbrok’s sons, seeking to match their father’s renown, embarked on widespread conquests across Zealand, Reidgotaland, Gotland, Öland, and various islets, with the astute Ivar leading and establishing a base in Lejre. To prevent his sons from outshining him, Ragnar appointed Eysteinn Beli as Sweden’s king, charging him to defend against them.

During Ragnar’s Baltic raids, his sons Eric and Agnar approached Lake Mälaren, demanding Eysteinn’s submission and his daughter Borghild for Eric. Eysteinn, after deliberation with chieftains, chose battle, leading to Agnar’s death and Eric’s capture.

Seeking to end hostilities, Eysteinn proposed peace by offering his daughter’s hand in marriage to Eric, along with a generous portion of Uppsala öd, the royal estates underpinning the Swedish crown’s wealth. However, Eric, overwhelmed by the ignominy of defeat, chose death over dishonor. He requested to be impaled on spears above the fallen, a wish that was solemnly fulfilled.

The news of the demise of Eric and Agnar spurred Aslaug and her sons to vengeance, successfully killing Eysteinn. Ragnar, disapproving of their autonomous retribution, aimed to outdo them by attacking England with immense ships. The Viking king is said to have ignored Aslaug’s advice against such vessels for the English shores.

In the end, Ragnar’s ambition led him to England, where he began a fierce campaign, showcasing the complex dynamics of ambition, loyalty, and familial legacy within the legendary Viking saga.
