三帝同盟
Chancellor Bismarck took full charge of German foreign policy from 1870 to his dismissal in 1890. His goal was a peaceful Europe, based on the balance of power, with Germany playing a central role; his policy was a success. Germany had the strongest economy on the Continent and the strongest military. Bismarck made clear to all that Germany had no wish to add any territory in Europe, and he tried to oppose German colonial expansion. Bismarck feared that a hostile combination of Austria, France and Russia could overwhelm Germany. If two of them were allied, then the third would ally with Germany only if Germany conceded excessive demands. The solution was to ally with two of the three. In 1873 he formed the League of the Three Emperors, an alliance of the kaiser of Germany, the tsar of Russia, and the emperor of Austria-Hungary. It protected Germany against a war with France. The three emperors together could control Eastern Europe, making sure that restive ethnic groups such as the Poles were kept in control. The Balkans posed a more serious issue, and Bismarck's solution was to give Austria predominance in the western areas, and Russia in the eastern areas. The system collapsed in 1887. Kaiser Wilhelm ousted Bismarck in 1890 and developed his own aggressive foreign policy. The Kaiser rejected the Russian alliance, and Russia in turn turned to an alliance with France.
