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? At the end of the day, it's the Vikings that are going to rule England. So for over 300 years, Viking culture had a huge impact on Europe. Really, their plundering and the terrorism that they put into the Dark Ages is unmarked in world history and certainly their mad seafaring technological skills have an impact on their world and they really created a larger economy at the end of the day.
