The Vikings show cast helped turn History’s historical drama into one of television’s most popular Viking sagas. Created by Michael Hirst, Vikings premiered in 2013 and ran for six seasons, following Ragnar Lothbrok, Lagertha, Rollo, Floki and eventually Ragnar’s sons as the story expanded from Scandinavian raids into a much larger struggle for power across England, France and the Viking world.
At the center of the series was Travis Fimmel as Ragnar Lothbrok, supported by Katheryn Winnick as Lagertha, Clive Standen as Rollo, Gustaf Skarsgård as Floki, Alexander Ludwig as Bjorn Lothbrok, Alyssa Sutherland as Queen Aslaug, and Alex Høgh Andersen as Ivar the Boneless. History’s official cast listings identify these performers among the show’s principal characters.
As the story moved beyond Ragnar, the Vikings cast changed significantly. New performers took center stage, particularly the actors playing Ragnar’s sons, while characters such as King Ecbert, King Harald Finehair, Judith and Ubbe became increasingly important to the story.
Vikings Show Cast at a Glance
The main Vikings TV show cast includes Travis Fimmel as Ragnar Lothbrok, Katheryn Winnick as Lagertha, Clive Standen as Rollo, Gustaf Skarsgård as Floki, George Blagden as Athelstan, Alexander Ludwig as Bjorn Lothbrok, Alyssa Sutherland as Queen Aslaug, Linus Roache as King Ecbert, Moe Dunford as Aethelwulf, Peter Franzén as King Harald Finehair, Alex Høgh Andersen as Ivar the Boneless, Jordan Patrick Smith as Ubbe, Marco Ilsø as Hvitserk and David Lindström as Sigurd Snake-in-the-Eye. History’s official cast pages list these characters and performers across the series.
Travis Fimmel as Ragnar Lothbrok
Travis Fimmel plays Ragnar Lothbrok, the central character who drives the early seasons of Vikings. Ragnar begins as an ambitious farmer and warrior who believes there are richer lands to the west and eventually becomes a powerful king. History describes him as a restless warrior and family man whose desire to explore new territories changes the fortunes of his people.
Fimmel’s performance is one of the defining elements of the Vikings show cast. He plays Ragnar as both a ruthless warrior and a complicated family man, allowing the character to shift between curiosity, arrogance, vulnerability and brutality without losing his core identity.
Katheryn Winnick as Lagertha
Katheryn Winnick plays Lagertha, Ragnar’s first wife and one of the most important characters in the entire series. Lagertha is portrayed as a formidable shield-maiden who fights alongside the men and eventually becomes a powerful political figure in her own right. History identifies her as an Earl and one of the show’s strongest warriors.
Lagertha’s importance to the Vikings cast goes far beyond her relationship with Ragnar. Her journey explores independence, leadership, motherhood and survival, and Winnick’s performance helped make Lagertha one of the series’ most recognizable characters.
Clive Standen plays Rollo, Ragnar’s older brother and one of the most unpredictable warriors in Vikings. Rollo is fiercely loyal to his brother at certain points but is also consumed by jealousy and a desire to step out of Ragnar’s shadow. History describes their relationship as intense and unpredictable.
Rollo becomes increasingly important as the series expands into France. His relationship with Princess Gisla and his eventual position as Duke of Normandy give his character a storyline that extends well beyond the early Viking raids.
Gustaf Skarsgård as Floki
Gustaf Skarsgård plays Floki, Ragnar’s eccentric friend and brilliant shipbuilder. Floki designs the ships that allow Ragnar and his fellow Vikings to travel farther across the sea, making him essential to Ragnar’s ambitions. History describes him as both a gifted shipbuilder and a deeply religious follower of the Norse gods.
Floki is one of the most distinctive members of the Vikings show cast because Skarsgård gives him a strange mixture of humor, unpredictability, loyalty and religious conviction. His relationship with Ragnar becomes increasingly complicated as the series progresses.
George Blagden as Athelstan
George Blagden plays Athelstan, the Christian monk whose capture by Ragnar becomes one of the show’s most important relationships. Athelstan’s knowledge of Christianity and the Anglo-Saxon world makes him valuable to Ragnar, but his presence also creates a continuing conflict between Christian beliefs and Norse religion.
Athelstan’s friendship with Ragnar gives Vikings one of its strongest cultural and philosophical storylines. His character is particularly important during the show’s early seasons because he becomes a bridge between two radically different worlds.
Alexander Ludwig as Bjorn Lothbrok
Alexander Ludwig plays Bjorn Lothbrok, Ragnar and Lagertha’s son. Bjorn begins the series as a young boy but gradually becomes one of its leading warriors and eventually a powerful ruler.
Ludwig takes over a much larger role as the series progresses, particularly after the story shifts toward Ragnar’s sons. Bjorn’s ambition, relationships and military campaigns make him one of the central figures in the later Vikings cast. History lists Ludwig as Bjorn in its official cast material.
Alyssa Sutherland as Queen Aslaug
Alyssa Sutherland plays Queen Aslaug, a major figure in Ragnar’s family and the mother of several of his sons. Her arrival changes Ragnar’s relationship with Lagertha and introduces a new political and personal dimension to the story.
Aslaug is particularly important because her children—including Ivar, Ubbe, Hvitserk and Sigurd—eventually become the next generation at the heart of the series. History lists Sutherland as Queen Aslaug among the principal Vikings cast.
Linus Roache as King Ecbert
Linus Roache plays King Ecbert of Wessex, one of Ragnar’s most intelligent political opponents. Unlike many rulers Ragnar encounters, Ecbert understands that diplomacy can sometimes accomplish what military force cannot.
The character becomes increasingly important as the Viking story expands into England. His relationship with Ragnar is built on mutual curiosity, manipulation and political calculation, giving the series some of its strongest strategic conversations.
Moe Dunford as Aethelwulf
Moe Dunford plays Aethelwulf, King Ecbert’s son and a major Anglo-Saxon warrior. Aethelwulf is frequently placed in direct conflict with the Viking armies, but his storyline becomes more complicated as he navigates his father’s political decisions and his own responsibilities.
History’s cast listings identify Dunford as Aethelwulf and place the character among the recurring major figures in the series.
Alex Høgh Andersen as Ivar the Boneless
Alex Høgh Andersen plays Ivar the Boneless, one of Ragnar’s sons and arguably the most psychologically complex member of the younger generation. Ivar’s physical disability does not prevent him from becoming an extraordinarily dangerous strategist.
Andersen’s performance becomes increasingly important after Ragnar’s departure from the main storyline. Ivar’s intelligence, ambition and cruelty make him one of the defining characters of the later Vikings TV show cast. History lists Andersen among the principal performers alongside the other sons of Ragnar.
Jordan Patrick Smith as Ubbe
Jordan Patrick Smith plays Ubbe, another of Ragnar’s sons. Compared with Ivar, Ubbe is generally more interested in cooperation and exploration than domination, making him one of the more balanced members of Ragnar’s family.
Ubbe’s journey becomes particularly important during the later seasons as the sons attempt to build their own identities rather than simply live in their father’s shadow. History’s cast information identifies Smith as Ubbe.
Marco Ilsø as Hvitserk
Marco Ilsø plays Hvitserk, one of Ragnar and Aslaug’s sons. Hvitserk’s storyline is shaped by his relationships with his brothers, especially Ivar, and by his struggle to determine where his own loyalties lie.
He becomes increasingly prominent in the later seasons as the rivalry between Ragnar’s sons intensifies. History lists Ilsø as Hvitserk in its Vikings cast information.
David Lindström as Sigurd Snake-in-the-Eye
David Lindström plays Sigurd Snake-in-the-Eye, another of Ragnar and Aslaug’s sons. Although his role is smaller than those of Ivar, Bjorn and Ubbe, Sigurd is part of the important transition from Ragnar’s generation to his children’s generation.
History’s official cast information identifies Lindström as Sigurd Snake-in-the-Eye.
Peter Franzén as King Harald Finehair
Peter Franzén plays King Harald Finehair, an ambitious Viking ruler whose desire to become king of all Norway brings him into conflict with Ragnar’s family and other Scandinavian leaders.
Harald becomes especially important in the later seasons, when the political landscape of the Viking world expands considerably. History lists Franzén as King Harald Finehair among the show’s major characters.
Jennie Jacques as Judith
Jennie Jacques plays Judith, the daughter of King Aelle and the wife of Aethelwulf. Her storyline becomes increasingly significant as the political and personal relationships between the Viking and Anglo-Saxon worlds become more complicated.
Judith is not simply a supporting royal character. Her decisions influence the succession and political structure of Wessex, and she becomes one of the more consequential female characters in the later seasons. History identifies Jacques as Judith in its cast listings.
Morgane Polanski as Princess Gisla
Morgane Polanski plays Princess Gisla, the daughter of Emperor Charles and the wife of Rollo. Her relationship with Rollo becomes an important part of the Paris storyline.
Gisla initially views the Vikings as enemies, but her relationship with Rollo evolves as his position in France changes. History lists Polanski as Princess Gisla among the show’s principal supporting characters.
Kevin Durand as Harbard
Kevin Durand plays Harbard, a mysterious traveler whose appearance in Kattegat creates one of the show’s more supernatural storylines.
Harbard’s presence is deliberately ambiguous, leaving viewers to question whether he is an ordinary man, a divine figure or something connected to the mythology that surrounds Ragnar and his people. History includes Durand’s Harbard among the show’s recurring characters.
John Kavanagh as the Seer
John Kavanagh plays the Seer, the mysterious spiritual figure consulted by Ragnar and other characters throughout the series. His prophecies frequently provide cryptic clues about the future of the Viking characters.
The Seer is particularly important to the show’s atmosphere because Vikings blends historical storytelling with Norse mythology and spiritual beliefs. IMDb lists Kavanagh among the long-running cast members, with the Seer appearing across much of the series.
Who Played Ragnar’s Sons in Vikings?
The Ragnar’s sons cast includes Alexander Ludwig as Bjorn Lothbrok, Alex Høgh Andersen as Ivar the Boneless, Jordan Patrick Smith as Ubbe, Marco Ilsø as Hvitserk and David Lindström as Sigurd Snake-in-the-Eye. These characters gradually become the central focus after Ragnar’s story moves into its later phase.
This transition is one of the defining structural choices of Vikings. Rather than simply ending Ragnar’s story and introducing unrelated protagonists, the series passes the narrative to his children, allowing the consequences of his choices to shape the next generation.

Who Are the Main Female Characters in Vikings?
The most prominent women in the Vikings cast include Katheryn Winnick as Lagertha, Alyssa Sutherland as Queen Aslaug, Jennie Jacques as Judith, Morgane Polanski as Princess Gisla, Josefin Asplund as Astrid and Georgia Hirst as Torvi.
Lagertha is particularly important because her storyline develops from Ragnar’s wife into that of an independent political and military leader. Torvi also becomes increasingly important during the later seasons, while Judith plays a significant role in the Anglo-Saxon political storyline. History’s official cast listings include these characters among the show’s major performers.
Which Vikings Cast Members Appeared in the Most Episodes?
The length of the series allowed several performers to remain on Vikings for much of its six-season run. IMDb’s series cast information lists Katheryn Winnick as Lagertha in 71 episodes, Gustaf Skarsgård as Floki in 68, Alexander Ludwig as Bjorn Lothbrok in 67, Georgia Hirst as Torvi in 62 and Alex Høgh Andersen as Ivar in 52.
Travis Fimmel’s Ragnar remains the defining face of the early seasons, appearing in 45 episodes before the story shifted toward the next generation.
Is the Vikings Cast Historically Accurate?
The Vikings cast portrays characters inspired by Norse sagas, historical figures and medieval sources, but the television series should not be treated as a literal historical record.
History itself describes the series as a scripted drama built around the saga of Ragnar Lothbrok, a character based on a real historical figure.
The show combines people and events from different periods, alters relationships and compresses timelines to create a coherent dramatic narrative. That is important when comparing the Vikings characters with historical accounts.
What Happened to the Original Vikings Cast?
The Vikings cast changed substantially as the story progressed. Ragnar’s departure shifted the focus toward his sons, while Lagertha, Rollo and Floki continued to have major arcs before eventually leaving the central storyline.
By the final seasons, Alexander Ludwig, Alex Høgh Andersen, Jordan Patrick Smith and Marco Ilsø were among the performers carrying the story forward. This generational transition gave the series a different tone while keeping Ragnar’s legacy at its center.
Where Is the Vikings Cast Now?
Many of the actors from Vikings have continued working in film and television after the series ended. Travis Fimmel has continued his screen career, while Katheryn Winnick, Gustaf Skarsgård, Clive Standen and Alexander Ludwig have also taken on projects outside the series.
The show’s international cast has helped several performers become closely associated with historical dramas, action television and genre entertainment. Their work on Vikings remains an important part of their careers, particularly for performers such as Winnick, Skarsgård and Ludwig.
Vikings Cast vs. Vikings: Valhalla Cast
The Vikings show cast should not be confused with the cast of Vikings: Valhalla. Although Vikings: Valhalla is set in the same broad historical universe and takes place more than a century after the original series, it features a different generation of characters and performers.
The original Vikings centers on Ragnar Lothbrok and his descendants, while Vikings: Valhalla follows historical figures including Leif Eriksson, Freydís Eiríksdóttir and Harald Sigurdsson.
Why the Vikings Cast Worked So Well
The biggest strength of the Vikings TV show cast was its ability to evolve with the story. Travis Fimmel established Ragnar as a charismatic but unpredictable protagonist, Katheryn Winnick gave Lagertha a powerful independent arc, and Gustaf Skarsgård made Floki one of the series’ most unforgettable personalities.
When Ragnar’s sons took over the narrative, performers such as Alexander Ludwig and Alex Høgh Andersen gave the later seasons their own identity. The result was a cast that could support a story spanning generations rather than depending on one central character.
Final Verdict on the Vikings Show Cast
The Vikings show cast remains one of the biggest reasons the historical drama continues to attract viewers. Travis Fimmel’s Ragnar and Katheryn Winnick’s Lagertha established the emotional foundation, while Clive Standen’s Rollo and Gustaf Skarsgård’s Floki added some of the show’s most unpredictable personalities.
The later seasons successfully shifted attention to Ragnar’s sons, with Alexander Ludwig, Alex Høgh Andersen, Jordan Patrick Smith, Marco Ilsø and David Lindström taking on increasingly important roles. Alongside them, performers such as Linus Roache, Peter Franzén, Jennie Jacques and Moe Dunford expanded the political world beyond Kattegat.
For anyone searching for the Vikings cast, the simplest way to understand the ensemble is to view it in two generations: Ragnar’s era and his sons’ era. That transition is what ultimately allowed Vikings to become a much larger saga about family, ambition, religion, warfare and the legacy one generation leaves behind.
