Ah thanks very much! This is good to know.Holy war CBs (except the Muslim one) revoke all titles held by people you consider infidels. You can then freely pass them out.
Claim CBs always revoke at least 1 county for the claimant.
Great Holy Wars revoke all titles held by infidels. Crusades are currently Great Holy Wars, but will become their own thing with Holy Fury.
Invasions usurp all titles held by the invader, but are either hard to get or hard to win.
The various pagan religions have some conquest CBs. Prepared invasions are limited to 1 per ruler. County conquests are a single county. Tengri have one that grabs a kingdom and all the stuff you have seiged down.
But what about strong/weak claims?
I for instance have a weak claim on hungary and managed to declare war on them as they have a Queen (I may or may Not have imprisoned the heir, waited for him to inherit the throne and then executed him to get his daughter on the throne).
Will I only get the King title as soon as I win?
