This is awesome. I love successful Silesias, although Saxon culture is a little disappointing. But if you're Saxon then take the rest of Saxony, reclaim Poland and maybe Bohemia and prove yourself the most powerful among the Great Powers.
Oh, they were Polish, then Silesian, so I thought Saxon should be also OK, but in fact I regret a bit too...
I will reclaim all Knights' land, then Wielkopolska, I'd release a Duchy of Krakow for Malopolska
