Vikings introduces viewers to Viking culture, though some characters may not have existed. Many characters were based on real people. Ragnar Lothbrok was a central character based on historical figures, though the existence of the real Ragnar is debated by historians. Characters like King Horik of Denmark and King Ecbert of Wessex were based on real rulers, with actual historical records to support their stories.

Vikings has done its best to introduce viewers around the world to Viking culture and Norse mythology, and while it has been as historically accurate as possible, it has obviously changed, added, or omitted many characters and events from the Viking age. However, there are many well-known characters that are based on real people. Created by Michael Hirst, Vikings made its debut on History Channel in 2013. Vikings initially followed the journeys of legendary Norse figure Ragnar Lothbrok (Travis Fimmel) and his Viking brothers.
