I am the King of Ireland, and I've conquered Wales and carved myself a good chunk out of the Kingdom of England. My goal is to drive the English off the island, and form the Empire of Brittania.
Problem is, the remaining English provinces are all ruled by one-province lords, except for the King, who has two (plus one in the Holy Land). Thus, the usual methods of fast expansion, such as smart marriages and duchy claims, are no longer effective, and taking the Kingdom one province at a time is tedious, tiresome, and time consuming.
If I decide work to usurp the King, will all his de jure vassals be transferred to me, or will they become independent?
My guess is that both the vassals and the former King will become independent, and that I may attempt to offer vassalage.
I have no claim to the title, and I don't care about it – in fact, I intend to destroy it as soon as possible. I just want more provinces. Therefore, it is imperative that I get as many vassals as possible in one swoop.
I'm playing an old version of Crusader Kings 2 (v2.0.4).
