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 streaming television series, Vikings: Valhalla, written and created by Jeb Stuart for Netflix, premiered on February 25, 2022.
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, marked by the Battle of Stamford Bridge in 1066, and the adventures of Leif Erikson, his sister Freydís, Harald Hardrada and the Norman King William The Conqueror. 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 Iceland to Norway, who are respectively pulled into the Viking campaign to conquer Great Britain and the growing religious divide between Christians and Pagans. As of 2022, The Seer (portrayed by John Kavanagh) is the only character to appear in both series.
