Vikings: Every Character Based On A Real Person

[هَـ-ђāŵĩ-ـَاوِيتم التحقق من هَـ-ђāŵĩ-ـَاوِي كعضو.]

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.
