I wish I could see more on this, but the superficial information that I could read in the article suggests that there were warlords in Viking society who were women.
I also don't have the knowledge to make full sense of the research itself.
I would love it if it's true.
Why? Because it'll show how backwards we have gone... not that we really need any more proof, but this could be a new measure on how unadvanced our advanced society has become.
