Bismarck pursued a largely successful foreign policy for Germany through a series of alliances and treaties. His main goals were to maintain peace in Europe, isolate France after its defeat in the Franco-Prussian War, and prevent the emergence of a powerful coalition that could threaten Germany. Key elements of Bismarck's foreign policy included the League of Three Emperors, the Congress of Berlin, the Dual Alliance between Germany and Austria-Hungary, and the Reinsurance Treaty with Russia. Through deft diplomacy and balancing of interests, Bismarck largely achieved his aims of stabilizing Europe under German dominance for nearly two decades.
