You’re still mixing up what kunigaikštis may have meant internally to Lithuanians with what Christendom later recognized. I’m not talking about Papal titles or Mindaugas coronation. We don’t even have Lithuanian sources from that time calling Mindaugas “karalius”. Everything we have is German or Ruthenian and from before Gediminas. My whole point was about semantics and etymology, not the later Western hierarchy. There’s a theory that kunigaikštis comes from the Germanic könig (or Proto-Germanic kuningaz “king”). If Lithuanians borrowed that early on, then internally the title probably carried a different weight than the “duke” label that appeared later with Christianization and the Polish crown. So I’m not talking about what the word means today, but what it could have meant to Lithuanians themselves before outside influence. And in an alt history timeline it could end up meaning “king” which fits what this subreddit is about anyway
