Prussia
Bismarck wanted unification to achieve his aim of a conservative, Prussian-dominated German state, attained through three wars.
Prussia and Austria were the two most powerful German states.
Adolf Hitler was born in Austria which makes his nationality Austrian, however ; Austrians are Ethnic Germans. Austrians speak German and have a Germanic culture. Which is why the Anschluss was wanted because Austria was forbid to join ''Germany unification in 1871'' by the Treaty of Versailles but dominated the German Confederation up until 1866 when it fought against Prussia another German state to see which states would join the German Unification. Adolf Hitler was a ethnic German. P.S His birthplace was once under rule by Bavaria which is now in modern-Germany. Austrian was his nationality German was his ethnicity - like all Austrians.
prussia
PRUSSIA is the answer you are looking for, but does not exactly fit the requirements of the question asked.Prussia was only the second-most powerful German State, but was effective in leading the unification movement by diplomatically and militarily side-stepping the more powerful Austria, which was the most powerful German State. Otto von Bismarck, Chancellor of Prussia, calculated that in order for Prussia to be the leader of a united Germany, Austria needed to be kept out and Bismarck had Prussia fight a war against the Austrians in 1866 in order to weaken the Austrian position,
The creation of a single German state occurred on January 18, 1871, when the German Empire was officially proclaimed in the Hall of Mirrors at the Palace of Versailles in France. This followed the Prussian victory over France in the Franco-Prussian War and the unification of various German territories under the leadership of Prussia's King Wilhelm I.
Piedmont
No. Italy was already an independent state from 1861. The Franco-Prussian War resulted in the unification of the North German Federation with the southern German states of Baden, Wurttemberg, and Bavaria and the former French territories of Elsaß-Lothringen to create the German Empire.
During the early nineteenth century, Prussia was the only German state that could match the power and influence of the Austrian Empire. They were comparable in terms of size, population and wealth. Austria opposed the idea of German unification as it saw this as a threat to its own empire. Although they were a minority, there was a significant percentage of German-speakers in the empire. If they broke away to join a unified Germany, Austria would be smaller and weaker. To this end, Prussia and Austria were rivals.
The act of unifying, or the state of being unified.
There have been several Pope Gregories. However all of them wanted more power, so in a restricted sense they did want some form of unification.
