If each nation—as defined by language, religion, common (legendary?) heritage, and location—was separate but equal, then all nations deserved to have their own states. Except by 1789, Poland had been partitioned between Russia, Prussia, and Austria, Bohemia had been inherited by the Austrians and then lost some territory to Prussia, Slovakia had been absorbed by the Hungarians since 925 or so, and the Hungarians were yoked to the Austrians through inheritance. And who was a German, anyway? Were Tyrolians German? What about people from Hamburg?
The Poles are very Catholic, although not as much as under Communism. One historian I heard described it as “practicing non-believers.” Even people who did not believe in G-d or the church attended mass, sent their children to church functions and schools, participated in church activities and so on because it was a way to preserve their identity and to stick one in the eye of the Communists. The down side was that to be “truly Polish” meant Catholic, with all that implied for Calvinists, Jews, Lutherans, and others. Uniates got a by, since they acknowledged the pope, and since the Soviets and Russian Orthodox had beaten up on them, too.
There is no other legend quite like the legend of the Confederate fighting man. He reached the end of his haunted road
