Im currently playing as the count of Northumberland, and through some scheming and warfare I have 2/3 of the de jure lands of the Duke of Northumberland. Do i need create a claim on the duchey? despite personally owning two thirds of it?
Is my only way to claim the duchal title through marriage?
It is a bit annoying to own more of Northumberland the the Duke, and i can't seem to work out how to get the title from him!
any help would be great!
