Primarily, I am looking at the differences between say, the movements for German unity and that of Italian nationalists.
The record shows that the people of Austria had accepted without much resistance their unification with Nazi Germany during the "Anschluss" (closing) of 1938. Yet other unification efforts before and after the Anschluss failed.
Considering the fact that almost all countries of Europe are organized on a linguistic basis, why did the movements for Austro-German unity fail?
