This here leads to several flaws in the game, serious ones.
1> Fighting defensive war against the mongols are hard because they can annex your land if they are the same as you and you cannot get it back except by sueing for peace if you are the same religion.
2> Wars against religious enemies are all or nothing, no real middle ground hardly because they don't realize you've taken some of their territory.
3> Empirers expand too rapidly and then fall flat on their face and are easily taken over. This is especially easy to see now with the mongols and chrisitan iberians which do well early on, but overreach and the other side doesn't know when its bitten off enough.
4> vassals created declare independance when wars end (bug)
Currently there is only 1 good historical element about the way its set up, that is if a marshal or someone takes a province, they become the ruler of that province. However that isn't enough to justify it as it stands now with all the flaws.
So i propose that the provinces don't automatically switch hands, but must be bargained for when sueing for peace, however unlike same-religion provinces the ruler doesn't need any claims on the province. This still helps the mongols out as well since they will be able to conquer easily with no claims needed anywhere.
As for the historic mention of commanders ruling provinces they conquered, they could be flagged to become a vassal of the lands he conquered assuming he is still alive, otherwise they'd revert to his liege.
