Thank all of you for explaining the situation!!!
In Europe there are many nations that live in individual states, so there is more of an emphasis on nationalities. But to give examples from countries near Slovakia, in Bohemia some people in Moravia feel more Moravian than Czech, in Germany some people in Bavaria feel more Bavarian than German. Btw, about Germany, there is one more thing, the former GDR may again separate from Germany. And now not on the basis of a political decision, but on the basis of the will of the citizens.
