What happened
In September 1862, with the Prussian House of Representatives refusing to approve King Wilhelm I's desired increase in military spending, the king appointed Otto von Bismarck minister president and foreign minister to break the deadlock. On 30 September 1862, Bismarck appeared before the parliament's budget committee and argued that Prussia's path forward depended on military strength rather than liberal constitutionalism. He told the committee that Germany looked to Prussia's power rather than its liberalism, and that the great questions of the age would be decided by iron and blood, not by speeches and majority resolutions, the mistake he said Prussia had made in 1848 and 1849.
Why it matters
The speech previewed, with unusual bluntness, the method Bismarck would actually use over the following decade: a sequence of wars, against Denmark in 1864, Austria in 1866, and France in 1870-71, engineered to unify the German states under Prussian leadership rather than any parliamentary consensus. Bismarck's rejection of the Frankfurt Parliament's failed liberal approach fourteen years earlier is explicit in the speech's reference to 1848 and 1849 as a mistake.
How we know
The speech survives as recorded, near-verbatim parliamentary testimony, preserved in Bismarck's collected works and translated in full by the German Historical Institute's document archive; the archive itself notes the record uses indirect reported speech typical of period parliamentary stenography rather than a word-for-word transcript.
