How did the Second Polish Republic work language wise?
As in how did they manage to live together with so many different languages, when i would assume most minorities didnt speak/learn polish before the independence. For example how many of of German, Ukrainians, Belarusians, and Jews spoke Polish and vice versa? How did they work together for example in the Army? Did the member of parliament speak in their own language or in polish in the parliament when making speeches? What languages were taught in schools? #local
