In September 1862, the Prussian House of Representatives refused to approve King Wilhelm I's requested increase in military spending. To break the deadlock, Wilhelm appointed Bismarck as Minister President and Foreign Minister, tasking him with resolving the constitutional crisis over army funding.
Bismarck appeared before the Budget Committee of the Prussian House of Representatives and argued that the great questions of the day could not be settled by speeches or majority votes, but only by iron and blood. This phrase, transposed into the more resonant 'Blood and Iron,' encapsulated his doctrine of Machtpolitik and his intent to pursue Prussian-led German unification through military strength.
The speech became symbolic of Bismarckian foreign policy and earned him the epithet 'the Iron Chancellor.' It foreshadowed the wars of German unification—against Denmark, Austria, and France—through which Bismarck forged the German Empire by 1871, validating his assertion that power, not liberal parliamentarism, would decide Germany's future.
