The conflict that this led to, when Matilda finally came over to England to pursue her claim in 1139, has been referred to by historians, since Victorian times, as the Anarchy. It won’t surprise you to hear that this term has since fallen out of favour. Apparently it’s a simplistic label. I’m sure it is, but that’s pretty much the deal with names. I’d say ‘Brian’ is a simplistic label for the guy who came to fix our washing machine, but it’s still his name. I don’t reckon we’d get to the root of the man any better by calling him Adrian.
