Or, in other words, the Battle of Stamford Bridge happened, when the last Viking army of consequence got comprehensively stomped by the last Anglo-Saxon king, shortly before he himself got killed by a bunch of Normans down at Hastings.
Given that the Normans were also of Viking stock, does this count as History's first rebranding exercise?
(Oh, how wonderfully right - the spell checker doesn't know 'jacksie', so suggests 'backside'.)
