The German War, also known as the Prussian-Austrian War, of 1866 was the military conflict between the German Confederation under the leadership of Austria on the one hand and Prussia and its allies on the other. In addition to the German states, Italy was also one of these allies. The conflict was the second of the so-called German Wars of Unification, after the preceding German-Dänish War and before the Franco-German War of 1870/71. - Wikipedia -
