Rückversicherungsvertrag
Unlike his successors, Bismarck viewed a war on two fronts as potentially fatal for Germany; his key foreign policy aims were friendship with Russia, and the isolation of France. When the French attempted to negotiate a Russian alliance in 1881, he persuaded Austria and Russia to join a reconstituted "Dreikaiserbund". Even after the League finally dissolved in 1887, Bismarck replaced it with the Reinsurance Treaty, a secret agreement with Russia to observe 'benevolent neutrality', in the event of an attack by France on Germany, or Austria-Hungary on Russia.
