Before 1866, Habsburg Austria and its German Confederation were the nominal leader in German affairs, but the Hohenzollern Kingdom of Prussia exercised increasingly dominant influence in German affairs, owing partly to its ability to participate in German Confederation politics through its Brandenburg holding, and its ability to influence trade through its Zollverein network. The question of excluding or including Austria's influence was settled by the Prussian victory in the Austro-Prussian War in 1866. The unification of Germany was made possible by the Franco-Prussian War of 1870–71, in which the smaller states joined behind Prussia in a smashing victory over France. The German Empire was put together in 1871 by Otto von Bismarck, who dominated German and indeed all of European diplomatic history until he was forced to resign in 1890.
