Read the full account
On 23 September 1862 King Wilhelm I appointed Otto von Bismarck minister-president of Prussia and, shortly after, foreign minister, to break the Landtag deadlock over the army bill. Bismarck had been ambassador at Paris. The appointment created the offices from which he later ran three wars and the Empire. It is not the Blood and Iron speech and not the 1871 chancellorship.
Context
The New Era liberal ministry had collapsed. Roon’s army reform needed money the Chamber of Deputies would not vote. A constitutional conflict was already open. Albrecht von Roon urged the king to call Bismarck. Moltke ran the General Staff, not the cabinet. Sharing the appointment with Wilhelm and Roon is required.
Shared responsibility is part of Wilhelm I appoints Bismarck Prussian minister-president and foreign minister. Naming Otto von Bismarck does not delete co-authors, institutions, or later transmitters. The lag from 1862-09-23 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.
Why it matters
The constitutional cost is a separate demo-worsening row.
