So I'm playing the carolingians storyline as a catholic italian, but I married my daughter to the prince of the byzantine empire and she converted to orthodoxy, so now when my character dies and she becomes the new ruler everybody hates her, and she doesn't have enough piety to convert to catholicism, so I have like 1000 factions forming to overthrow her, what do I do? (The new ruler has high martial skills if that helps)
