Vikings is an Irish-Canadian 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 the United States and Canada.
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. The show portrays Ragnar as a former farmer who rises to fame by successful raids into England, and eventually becomes king of Denmark, with the support of his family and fellow warriors: his brother Rollo, his son Bjorn Ironside, and his wives—the shieldmaiden Lagertha and the princess Aslaug.
On March 26, 2015, History renewed Vikings for an extended fourth season of 20 episodes, which is set to premiere on February 18, 2016.
