The only thing you haven't replaced is the beaucracy, which needs more than some fancy titles xolors and elections to change how it works.
No, I have replaced the bureaucracy. The ducal offices were all purged with Quintus' fall. New people were brought in from other theocracies.
You lost the nobles and territory for unrelated reasons.
LOL. Wow. You're funny. I think you don't get what's going on.
