A What If Question

I googled the first part of that and was about to be pretty impressed but then I googled "Harald Hardrada was the King of Norway. Hardrada had ruled Norway jointly with his nephew Mangus until 1047 when Mangus conveniently died. Earlier (1042), Mangus had cut a deal with Harthacut, the Danish ruler of England. Since neither ruler had a male heir, both promised their kingdom to the other in the event of his death. Harthacut died but Mangus was unable to follow up on his claim to the English throne because he was too busy battling for the rule of Denmark, and so Edward became the Anglo-Saxon ruler of England. Now with Mangus and Edward dead, Hardrada asserted that he, as Mangus' heir, was the rightful ruler of England. When he heard of Harold's coronation, Hardrada immediately prepared to invade England and crush the upstart." and that is verbatim from a website I am disappointed in you Lenny.
