Stories of Viking conquests are the stuff of legends. What is lesser known, however, is the indelible influence these raiders had on the British Isles. Far from the dominant narrative that Vikings simply conquered and took their leave, recent genetic testing has revealed that the Vikings never completely left the Isles. This documentary follows the progress of Danish Viking King Canute, who built his North Sea Empire across Britain and Scandinavia. Watch enthralled as the series tells the tale of indelible ways Viking culture integrated with the indigenous cultures of the British Island-some of which can be traced to common customs and practices in the present day.
