Yeah, so basically a form of government where the nobles do not have true choice in matters. Its an oligarchy. There are a few in power who control the thoughts of the others, you are not allowed to choose for yourself, therefor you live in an oligarchy and a vassal of the Theocracies... Not a true republic , nor even a free nation... Thank you for showing Dwilight that you cannot have claim over Asylonian lands when you cannot even have control over your own realm.

Good one, Glaumring. You just showed us how a "Republic" in a game, and on an island, set in a Middle Ages model, is not a true "free" nation. No kidding, man. No freaking kidding.
