Range has been a bad boy and if Poland isn't worse than dishonorable scum, it must already be hated throughout the entire world.
1746. Poland started a war of aggression against Sweden. This is where the world realised you were dishonorable scum and they'll go on beserkly attacking Poland until it has been partitioned enough to lose its scummy reputation. With all the annexations you've done since then, its going to take a lot of partitioning before Poland will be allowed to exist in peace.
Don't worry, annexing the Russian snows entirely still counts as a white peace.
I think they're a major power, though, and that major powers can't be annexed in EU1. I may be wrong on one or both points but that is my recollection.
