1866–1878: beyond Lesser Germany

The Austro-Prussian war was ended by the Peace of Prague (1866) which settled the " German question " in favor of a Lesser German Solution. Count Friedrich Ferdinand von Beust, who was the foreign minister from 1866 to 1871, hated the Prussian chancellor, Otto von Bismarck, who had repeatedly outmaneuvered him. Beust looked to France for avenging Austria's defeat and attempted to negotiate with Emperor Napoleon III of France and Italy for an anti-Prussian alliance, but no terms could be reached. The decisive victory of the Prusso-German armies in the Franco-Prussian war and the subsequent founding of the German Empire ended all hope of re-establishing Austrian influence in Germany, and Beust retired.

After being forced out of Germany and Italy, the Dual Monarchy turned to the Balkans, which were in tumult as nationalistic movements were gaining strength and demanding independence. Both Russia and Austria–Hungary saw an opportunity to expand in this region. Russia took on the role of protector of Slavs and Orthodox Christians. Austria envisioned a multi-ethnic, religiously diverse empire under Vienna's control. Count Gyula Andrássy, a Hungarian who was Foreign Minister (1871–1879), made the centerpiece of his policy one of opposition to Russian expansion in the Balkans and blocking Serbian ambitions to dominate a new South Slav federation. He wanted Germany to ally with Austria, not Russia. ]
