I'm trying to cause the destruction of an empire-level title (say Byzantine Empire), to create the Latin Empire organically instead of starting with it. As ERE is (still) large, conquering all of it would take enough time, and I already fulfill the other requirements to form the Latin Empire.
What would be an efficient way to destroy the title without too much war effort? One solution I was thinking about is taking away all county-level holdings from the current emperor through wars, but I'm not entirely sure it will work, and it would take some years to get to that point with the current state of affairs.
Will this work? Are other ways to go about it?
