# The Peace of Prague excludes Austria from German affairs

Date: 1866

## The fact

On 23 August 1866 the Peace of Prague ended the Austro-Prussian War: the German Confederation was dissolved, Austria withdrew from German politics, and Prussia gained a free hand to organize the north. [Bismarck](/people/otto-von-bismarck) pushed a peace short of Habsburg dismemberment. This is the settlement, not the battle and not the later imperial constitution. Later museums, competitions, UNESCO lists, and translations are not this Fact. The Reichstag, Wilhelm I, Moltke, Roon, and state administrations may share the file; they do not erase a documented decision, and they are not a licence to treat every regiment’s act as his handwriting.

## Context

Napoleon III’s mediation and the need to keep Austria from a revenge alliance shaped terms. The south remained nominally independent pending later treaties. Hungarian settlement inside Austria is not Bismarck’s act. Cohesion here means a smaller German political space without two great-power vetoes. Later museums, competitions, UNESCO lists, and translations are not this Fact. The Reichstag, Wilhelm I, Moltke, Roon, and state administrations may share the file; they do not erase a documented decision, and they are not a licence to treat every regiment’s act as his handwriting.

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

## Evidence and sources

GHDI publishes Prague-peace documents. Britannica independently dates the treaty. Diplomatic histories independently credit Bismarck’s restraint versus the king’s annexation mood. Later museums, competitions, UNESCO lists, and translations are not this Fact. The Reichstag, Wilhelm I, Moltke, Roon, and state administrations may share the file; they do not erase a documented decision, and they are not a licence to treat every regiment’s act as his handwriting.

## Significance

Improving cohesion path for a kleindeutsch state system. Complex. Medium confidence on welfare sign because the war row already stores the dead. Later museums, competitions, UNESCO lists, and translations are not this Fact. The Reichstag, Wilhelm I, Moltke, Roon, and state administrations may share the file; they do not erase a documented decision, and they are not a licence to treat every regiment’s act as his handwriting.

Confidence is stated on the impact path, not hidden in adjectives. Do not treat Prague as Königgrätz. Do not treat it as the 1871 proclamation. Mixed effects of The Peace of Prague excludes Austria from German affairs are separate paths.

## What is established and what is not

Established: the 23 August 1866 peace excluded Austria from German affairs on Bismarck’s terms. Not established: that the peace made 1870 inevitable. Later museums, competitions, UNESCO lists, and translations are not this Fact. The Reichstag, Wilhelm I, Moltke, Roon, and state administrations may share the file; they do not erase a documented decision, and they are not a licence to treat every regiment’s act as his handwriting.

Shared responsibility is part of The Peace of Prague excludes Austria from German affairs. Naming Otto von Bismarck does not delete co-authors, institutions, or later transmitters. The lag from 1866-08-23 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.

The attached driver is [social-cohesion](/drivers/social-cohesion). The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself.

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