# List of Vikings and Vikings: Valhalla characters

Vikings is a historical drama television series written and created by Michael Hirst for the television channel History. Filmed in Ireland, it premiered on 3 March 2013 in Canada, concluding on December 30, 2020. A standalone sequel series, Vikings: Valhalla, written and created by Jeb Stuart for Netflix, premiered on February 25, 2022, concluding on July 11, 2024.
Vikings is inspired by the sagas of Viking Ragnar Lothbrok, one of the best-known legendary Norse heroes and notorious as the scourge of England and France, while Vikings: Valhalla, set 100 years later, chronicles the beginning of the end of the Viking Age and the adventures of Leif Erikson, his sister Freydís Eiríksdóttir and Harald Sigurdsson. The broad historical narrative of both series are based on real events, with some of the principal characters representing real figures from history and/or legend.
Vikings portrays Ragnar as a former farmer who rises to fame by successful raids into England, and eventually becomes king, with the support of his family and fellow warriors: his brother Rollo, his son Björn Ironside, and his wives—the shieldmaiden Lagertha and the princess Aslaug. Vikings: Valhalla portrays Leif and Freydís as immigrants from Greenland to Norway, who are respectively pulled into the Viking campaign to conquer Great Britain and the growing religious divide between Christians and Pagans. The Seer (portrayed by John Kavanagh) is the only character to appear in both series, having appeared in at least one episode of every season.

#### Rollo

* Played by Clive Standen (seasons 1–5)

Earl Haraldson's wife, and later the lover of Rollo. She possesses a strategic mind and an urge to regain her power and influence, but grows to care for Ragnar and his family. She drowns while attempting to save Ragnar's children from a similar fate as her own.

* Played by Gustaf Skarsgård (seasons 1–6)
A gifted but eccentric shipbuilder and friend of Ragnar. His ships create a revolution in shipwright techniques. He considers himself descended from the trickster god Loki and is very devout in the Norse religion. Loosely based on the historical Hrafna-Flóki Vilgerðarson.

#### Athelstan

* Played by George Blagden (seasons 1–4)
An Anglo-Saxon monk from the monastery of Lindisfarne in Northumbria.

#### Emperor Charles of West Francia

* Played by Lothaire Bluteau (seasons 3–4)

#### The Seer

* Played by John Kavanagh (seasons 1–6; Valhalla)
Seiðr of Kattegat. A 200-year-old blind being who often provides mysterious predictions to the characters. He is murdered by Ivar after refusing to recognise Ivar as a god and predicting Ivar's fall.

She is killed in battle and he vows vengeance on Lagertha. He sails with Bjorn to retake Kattegat, but their fleet is damaged by a storm. Harald saves Bjorn's life but takes a serious battle wound. Olaf rescues Harald, but occupies Vestfold. Harald's men beg Bjorn for help, and Bjorn repays his debt. When Olaf tries to have Bjorn elected as over-king of Norway, Harald defeats Bjorn in the election, but Harald's men fail to kill Bjorn. Olaf refuses to recognise Harald, so Harald has him put away and sends warriors to secure his borders.
Based on the historical Harald Fairhair.

#### Halfdan the Black

* Played by Jasper Pääkkönen (seasons 4–6)
Harald's violent younger brother. He hates Christians and tries to kill as many as possible. He grows tired of living in his brother's shadow and of Harald's war with other Norsemen, and joins Bjorn's expedition to the Mediterranean. They form a close friendship which leads Halfdan to join Lagertha's side when Ivar and Harald declare war. Faced by Harald in battle, he is killed.

When Lagertha is driven into exile in England, Ubbe becomes Alfred's advisor and converts to Christianity. Based on the historical Ubba.

Having become smitten by Lagertha, he seduces her and switches to her side. On his suggestion, Lagertha and her followers seek refuge in England. Through Heahmund's influence, the Northmen are given sanctuary in return for fighting against other Viking raiders. When Harald Finehair attempts to raid Wessex, Heahmund fights in the frontline. In the battle he is wounded by arrows and killed by Gunnhild. Broadly inspired by the historical Heahmund.

The Varangian (east European Viking) ruler of Kiev, called "the Prophet". He is the protector of the heir to the Rus kingdom, Igor and brother in law of Igor's father Rurik.

He has successfully sacked Constantinople, but is critical of Rurik's eastward expansion. Oleg wants to conquer Scandinavia which he claims is the property of the Rus. Oleg takes in Ivar, thinking him useful for his plan to invade Scandinavia. Oleg forms an uneasy friendship with Ivar after revealing that he murdered his wife after discovering her infidelity. Ivar's similar experience with Freydis brings them closer. The character is based on the semi-historical Oleg the Prophet.
