Read the full account

On 20 July 1933 the German Reich and the Holy See signed a concordat. It is a dated treaty. Later violations are other rows. Adolf Hitler's documented role is: His government signed. Papen negotiated; Pius XI's secretary Pacelli signed for the Holy See. Later encyclical is a neighbouring file.

Context

Centre Party had dissolved. Sharing signature with Pacelli and Papen is required. The setting of The Reich signs a concordat with the Holy See is the public file around 1933-07-20. Driver institutional-corruption is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

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

Why it matters

High confidence on the signature. The welfare reading on this path is worsening.

Shared responsibility is part of The Reich signs a concordat with the Holy See. Naming Adolf Hitler does not delete co-authors, institutions, or later transmitters. The lag from 1933-07-20 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.
