I'm currently holding the Kingdom of Wales and working on expanding into England with the help of powerful allies. My government type is Absolute Cognatic Primogeniture (first born child of the ruler inherits all titles regardless of gender) but all these vassal republics keep popping up all over the place within my realm. I know the republics can be great moneymakers but the cons are outweighing the pros for me at the moment. Republics are elective so every time I finally get my direct vassals (who are almost all mayors) to approve of me, they die and a new mayor is elected who hates me and I have to start the process all over again, not to mention that they all just flat-out hate my guts to begin with no matter how great of a ruler I am, because, according to them, I'm the wrong government type.
I'd like to turn all these republics into something hereditary (preferably gavelkind succession, keeps them too weak to rise up against me and at least I always know who's going to take over when my vassals die). I don't care much about their gender laws, I don't think they can adopt absolute cognatic without being basque, Cathar or Messalian anyway. How could I go about doing that? Will simply revoking all their titles and giving them to my family members instead solve my problem? I think I've tried that before and the family member I gave the title to just ended up being a mayor of a republic, anyway.
