The Austro-Prussian War in 1866 was the result of Austria's opposition to unification. True False

This is false, as German unification was not complete after the war.  The war (sometimes referred to as the Seven-Weeks War) was started over a dispute over the ownership of the duchy of Schleswig-Holstein.  Denmark occupied Schleswig, and Germany occupied Holstein.  In 1846, Denmark occupied both duchies.  The combined forces of Austria and Germany went to war with Denmark in 1864 and drove out the Danish.  Schleswig was to be ruled by Germany, and Austria was to be ruled by Holstein.  In 1864, Kaiser William I of Germany and his Prime Minister Otto von Bismark thought that Austria was becoming too powerful, so Bismark, insisted on a war with Austria in order to check its growing power in Europe.  Germany (dominated by Prussia) defeated a conglomeration of Austria, Italy, and smaller southern German states.
