In the Faq by Aetius:
"Conquest
There is no such thing (a temporary CB) in CK. You must have a claim to get a CB for a war that give you a vassal or demesne. Certain *things* may give you non-claim CB's but then you can only get tribute. There are no Peace Treaties with penalties for war mainly because the prerequisites for war will be much tougher in CK than in for example EU2. Greven
Basically if you defeat another ruler you might get his vassals. That is either that his old vassal become your vassal or that you install your own vassal there. At some occasions you may turn a conquered province into a Demesne Province (which is approximately as EU2 owned provinces). Though you never hold many Demesne provinces.
The important change is that you must have a claim on a province to get it at all." Greven
Heres my question: How do you get a claim on a province?
