Read the full account

On 18 June 1887 Germany and Russia signed the secret Reinsurance Treaty: neutrality if the other were at war with a third power, with exceptions for wars against Austria or France depending on who attacked. Bismarck used it to replace the dead Three Emperors’ League. The Reichstag did not ratify a secret instrument. This is not the Dual Alliance.

Context

Bulgarian crises had wrecked the 1881 three-emperor treaty. France was still the named enemy. Secrecy vis-à-vis Vienna was part of the design. Caprivi’s 1890 refusal to renew is another person’s act. Polarization here is interstate.

Why it matters

Improving polarization path (weakening a two-front immediate lock). Medium confidence because secrecy itself is a democratic cost stored only as context.

If a number is not in the two records named above, it is not supplied here.

    A back-channel neutrality pledge reduced the immediate risk of a Franco-Russian vice, weakening short-run polarization at the cost of secrecy.

What the sources establish

Avalon publishes the Reinsurance Treaty. Britannica independently dates it. German and Russian documentary editions independently confirm secrecy.

Established: a secret Reinsurance Treaty was signed on 18 June 1887 under Bismarck. Not established: that Wilhelm II was bound to renew it, or that 1914 was thereby blocked.

Confidence is stated on the impact path, not hidden in adjectives. Mixed effects of Germany and Russia sign the Reinsurance Treaty are separate paths.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

That reading is an impact-path choice, not a property stored on the Fact itself.

Shared responsibility is part of Germany and Russia sign the Reinsurance Treaty. Naming Otto von Bismarck does not delete co-authors, institutions, or later transmitters. The lag from 1887-06-18 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
