Isnt the requirement to restore Roma that you be an Orthodox faithful/Orthodox heretic, no Catholics allowed?I'm not the King of Italy yet, dear old mom is still alive (albeit in an Italian jail at 65-ish) so I haven't inherited her claim yet. I'm the legit Emperor, though, so I can still freely revoke the duke vice-royalties.
Edit: Also, oddly enough, between my 20 diplo, +25 from crushing a major revolt, and +25 for educating my heir as Greek, I'm just asking my vassals to convert and they are.
