Dual Alliance between Germany and Austria-Hungary from October 7, 1879
Secret Treaty, Partial Publication in the Reichs- und Staatsanzeiger on February 3, 1888
Inasmuch as Their Majesties the Emperor of Austria, King of Hungary, and the German Emperor, King of Prussia, must consider it their imperative duty as monarchs to provide for the security of their empires and the peace of their subjects, under all circumstances;
inasmuch as the two sovereigns, as was the case under the former existing relations of alliance, will be enabled by the close union of the two empires to fulfil this duty more easily and more efficaciously;
inasmuch as, finally, an intimate cooperation of Germany and Austria-Hungary can menace no one, but is rather calculated to consolidate the peace of Europe as established by the stipulations of Berlin;*
Their Majesties the Emperor of Austria, King of Hungary, and the Emperor of Germany,** while solemnly promising each other never to allow their purely defensive agreement to develop an aggressive tendency in any direction, have determined to conclude an alliance of peace and mutual defense.

Article I. Should, contrary to their hope, and against the loyal desire of the two high contracting parties, one of the two empires be attacked by Russia, the high contracting parties are bound to come to the assistance one of the other with the whole war strength of their empires, and accordingly only to conclude peace together and upon mutual agreement.+
