The Vikings Season 1 Episode 30 Collapse of Cnut

At Cnut's death, his sons clashed for control while also fending off Magnus the Good of Norway. In 1066, with Cnut's sons both dead and his nephew Svein Estrithson holding Denmark, Magnus's uncle Harald Hardardi attempted to wrest England from Cnut's distant relative Harold II. Harold repelled Hardardi but fell at Hastings to William the Conqueror, who had just begun to put Normandy on the map.
