He came back to co-rule with his nephew, who then suspiciously died and King Harald became the king of Norway. He's going to make one last venture for the Vikings into Europe and try to create an empire, a Viking empire, and he invades England in 1066. It's called the Battle of Stamford Bridge and he was really cocky. He was really good at what he did, but he was outmaneuvered and he was outnumbered by the English, who eventually defeat him and that's really going to be the last hurrah for the Vikings. Interestingly enough, in 1066, when the English defeat the Norwegian Vikings, it's the same year that they're defeated by the Normans at the Battle of Hastings. And then to make it more ironic, it's actually William the Conqueror and he is the grandson of a Viking. So how about that?
