What is blood and iron speech?

The "Blood and Iron" speech was delivered by German Chancellor Otto von Bismarck in 1862. The speech outlined Bismarck's plans to unify the German states under Prussian leadership through a policy of "blood and iron," meaning that unification would be achieved through military force and diplomacy rather than through idealistic or peaceful means. The speech emphasized the idea of strength and unity as essential components for achieving political and territorial goals. Bismarck's policies were successful in leading to the unification of Germany in 1871. The "Blood and Iron" speech is often cited as a key moment in German history and Bismarck's career as a statesman.
