I believe i once read something that said that Fredrick had offered his assistance to Maria Theresa in defending her right to the Habsburg crown lands in exchange for Silesia (or parts of it) now I am unsure of the validity of this and even if it had happened it would have been refused with good reason but for the sake of discussion say it does happen, Maria accepts (I'm mean she wouldn't bit bear with me) and Frederick takes the task seriously how does this effect a potential alt war of Austrian succession?
