So, I have created the vast empire of Oceania, where 2 + 2 = 5. Ireland , Scotland, Wales and England are dejure part of it. I used to own all kingdoms, but i was forced to give Ireland in order to avoid revolts. After some revolts by the vassals of Ireland, they changed the council authority to max and the succession law to Elective. Now, since both the authority and the succession type are what they are, I cannot change the succession to primogeniture, but since The kingdom is not my primary title, I cannot change it's council laws. (I can only change the empire laws). So, what do I do? How do I change from a full council authority - elective succession, to primogeniture?
