So Im playing as Brandenburg and Im at war with Bohemia. I have a vassal of Moravia who I want to feed Praha to since its over 350 adm to core. I fear that Moravia will just accept the emperors request to return the province as this happened to me before when I tried to feed Nassau to my vassal Hessen. Back then the Emperor was Austria who I was allied to and had friendly relations. Now England is the emperor and I have neutral relations with him and he isnt very strong. And if i take the province myself and then just sell it to Moravia (I dont have Cossacks) will the ai ask to return province again?
