Why my vassal can still declare war when vassal war is illegal?

[Amelia1812]

I have banned war declaration, but why my daughter can still declare war?

 

[Boodas]

That law only applies to De-jure Vassals, Defacto Vassels can still declare wars.

That law only applies to De-jure Vassals, Defacto Vassels can still declare wars.

Wrong, partially.

If they are defacto, but neither their dejure kingdon or empire currently exist, they *will* default to your crown laws.


HOWEVER; tribal vassals *ignore* crown laws entirely; and even with feudal vassals, illegal vassal wars *only* block claim and border dispute wars

Crown laws cannot prevent invasion and holy war CBs
