I'm wondering if there's any possibility of the third partition of Poland taking a different form and the Austrians (either in addition to or instead of southern Poland) take southern Belarus along these lines?
Would Austria have been interested and would Russia have gone along?
How likely is it that Austria would have done so? I confess to ignorance on the topic. (I'm reading a book about the development of Polish, Lithuanian, Belarussian and Ukrainian nationalism, and it got me curious about the idea of a Belarussian counterpart to Habsburg Galicia.)
