1866       


After the Austro Prussian War of 1866, many Middle-German states, Hanover, Hesse-Cassel, Nassau, The Duchies of Schleswig and Holstein and Lauenburg and the Free City of Frankfurt, traditional allies of Austria, were annexed by Prussia. The north of Germany was now completely dominated by Prussia. As Austria's traditional ambitions in Germany were now finally defeated, the German Confederation under its leadership was discontinued. Instead the Prussians erected a North-German Confederation including Prussia and the remaining smaller states there.
