I'm adding two nations since they're incredibly tiny (and shitholes)
1: The County of Novy Targ is a small city-state which is being taken over by Hungary due to its tiny size, the fact that it is only allied with west Kraków, and its current rebellion. It's not a very nice place to live.
2: The Republic of Katowice is a failed state, a dictatorship which attempted republican revolution earlier in the century but now has a strong dictator who is attempting to isolate it from the outside world and is generally insane, with such glorious things as wanting to annex Prussia and form the great Prussian Empire to uniting the entire Polish sphere under his flag of fascism. He is incredibly militaristic and has built a stone wall surrounding the entire country. Silesia, Poland, and Hungary are hungrily waiting for him to die so they can occupy their claims, however, since they are highly overlapping it is a recipe for future disaster.
