German question
Resistance against the French revolution with its concept of the state brought a new movement to create a German "ethnical state", especially after the Napoleonic wars. Ideal for this state was the Holy Roman Empire; the legend arose that Germany were "un-defeated when unified", especially after the Franco-Prussian War ("", lit. "German-French war"). Before that, the German question ruptured this "German unity" after the 1848 Revolution before it was achieved, however; Austria-Hungary as a multinational state could not become part of the new "German empire", and nationality conflicts in Prussia with the Prussian Poles arose ("We can never be Germans – Prussians, every time!").
