Three Emperors’ Treaty between Germany, Austria-Hungary, and Russia from June 18, 1881
The courts of Austria-Hungary, of Germany, and of Russia, animated by an equal desire to consolidate the general peace by an understanding intended to assume the defensive position of their respective states, have come into agreement on certain questions which more especially concern their reciprocal interests.
With this purpose the three courts have appointed: […][1]
Article I. In case one of the high contracting parties should find itself at war with a fourth Great Power, the two others shall maintain towards it a benevolent neutrality and shall devote their efforts to the localization of the conflict.
This stipulation shall apply likewise to a war between one of the three powers and Turkey, but only in the case where a previous agreement shall have been reached between the three courts as to the results of this war.
In the special case where one of them should obtain a more positive support from one of its two allies, the obligatory value of the present article shall remain in all its force for the third.
Article II. Russia, in agreement with Germany, declares her firm resolution to respect the interests arising from the new position assured to Austria-Hungary by the Treaty of Berlin.
The three courts, desirous of avoiding all discord between them, engage to take account of their respective interests in the Balkan Peninsula. They further promise one another that any new modifications in the territorial status quo of Turkey in Europe can be accomplished only in virtue of a common agreement between them.

Article III. The three courts recognize the European and mutually obligatory character of the principle of the closing of the Straits of the Bosphorus and of the Dardanelles, founded on international law, confirmed by treaties, and summed up in the declaration of the second Plenipotentiary of Russia at the session of July 12 of the congress of Berlin (Protocol 19).[2]
They will take care in common that Turkey shall make no exception to this rule in favor of the interests of any government whatsoever, by lending to warlike operations of a belligerent power the portion of its empire constituted by the Straits.
In case of infringement, or to prevent it if such infringement should be in prospect, the three courts will inform Turkey that they would regard her, in that event, as putting herself in a state of war towards the injured party, and as having deprived herself thenceforth of the benefits of the security assured to her territorial status quo by the Treaty of Berlin.
Article IV. The present treaty shall be in force during a period of three years, dating from the day of the exchange of ratifications.
Article V. The high contracting parties mutually promise secrecy as to the contents and the existence of the present treaty, as well as of the protocol annexed thereto.
Article VI. The secret conventions concluded between Austria-Hungary and Russia and between Germany and Russia in 1873 are replaced by the present treaty.
Article VII. The ratifications of the present treaty and of the protocol annexed thereto shall be exchanged at Berlin within a fortnight, or sooner if may be.[3]
