If you’re a fan of epic historical series and have wondered how real the Cast of Vikings actually is, you’re in the right place. Vikings, available for streaming on Netflix, masterfully blends real history with dramatic storytelling, creating one of the most captivating shows of the past decade.
In this guide, we dive deep into the main characters of Vikings who were based on real historical figures — and we’ll also show you where to watch the full saga online.
Main Characters of Vikings Based on Real People
1. Ragnar Lothbrok
Let’s start with the heart of the Cast of Vikings: Ragnar Lothbrok, portrayed by Travis Fimmel. Ragnar is legendary among Norse tales — a fearless warrior and king said to have led raids into England and France during the 9th century.
Although historians debate his actual existence, Ragnar’s name lives on in numerous sagas, inspiring countless generations.
2. Lagertha
Another standout among the Vikings cast is Lagertha, played by Katheryn Winnick. According to Saxo Grammaticus’ chronicles, Lagertha was a fierce shieldmaiden who fought alongside male warriors — an early icon of female strength and independence.
Whether she was real or mythologized, Lagertha remains one of the most beloved characters.
3. Bjorn Ironside
Bjorn, the son of Ragnar and Lagertha, led expeditions across the Mediterranean and helped shape early Swedish royal history. His legacy of exploration and conquest cements his place among the most important real-life inspirations for the Cast of Vikings.
4. Ivar the Boneless
Known for his nickname, possibly due to a medical condition, Ivar was a real commander of the Great Heathen Army. His ruthless tactics and battlefield genius are well-documented in historical texts.
In the series, Ivar becomes one of the most complex and chilling figures among the Vikings characters.
5. Rollo
Rollo, Ragnar’s brother in the show, was based on Hrolf Ganger — the Viking leader who became the first Duke of Normandy. His descendants include William the Conqueror and other European royalty.
In other words, Rollo’s legacy reaches far beyond Scandinavia.
6. Floki
Floki, the eccentric boat builder portrayed in Vikings, was inspired by Hrafna-Flóki Vilgerðarson, credited as one of the first Norse explorers to intentionally sail to Iceland.
His adventurous spirit and quirky personality are key to why Floki became a fan-favorite.
7. King Ecbert
King Ecbert of Wessex, a major character interacting with the Cast of Vikings, was a historical figure known for his political brilliance and ambition. He played a crucial role in the formation of what would later become England.
8. King Aelle
King Aelle of Northumbria famously executed Ragnar according to Viking sagas — a brutal act that sparked vengeance by Ragnar’s sons. His character in the series reflects the tensions between Anglo-Saxons and Viking invaders during the era.
9. Athelstan
Among all characters, Athelstan holds a special place in the hearts of fans. Played by George Blagden, Athelstan is a former Christian monk who gets caught between two worlds: Viking paganism and Christianity.
Although Athelstan wasn’t directly based on a single historical figure, he represents the real cultural exchanges (and conflicts) between Norse pagans and Christian societies during the Viking Age.
His deep friendship with Ragnar and internal struggles make him one of the most compelling characters in the Cast of Vikings.
10. Ubbe
Ubbe, portrayed by Jordan Patrick Smith, emerges as one of the key figures in the later seasons. He embodies Ragnar’s dream of exploration and peaceful settlement.
Historically, Ubbe Ragnarsson was a leader of the Great Heathen Army and played a vital role in Viking efforts to establish territories in England.
In the show, Ubbe’s story even ventures towards North America, symbolizing the endless Viking desire to discover new worlds.
Where to Watch Vikings Streaming Online
Now that you know the real stories behind the Cast of Vikings, it’s time to watch (or rewatch!) their epic journeys. All six seasons of Vikings are available for streaming on Netflix.
Netflix offers the full series in stunning HD, allowing you to immerse yourself completely in the world of Ragnar, Lagertha, Bjorn, and all the other unforgettable characters.
Why the Cast of Vikings Still Captivates Us
Beyond the bloody battles and political intrigue, what truly sets Vikings apart is the authenticity and humanity the actors brought to their roles. Whether it’s Travis Fimmel’s brooding intensity as Ragnar or Katheryn Winnick’s fierce portrayal of Lagertha, each member of the Cast of Vikings made these historical (and legendary) figures feel real.
Their struggles, ambitions, and sacrifices remind us that history is not just about dates and battles — it’s about people.
