How did Bismarck manage to form a united Germany?

Otto Von Bismarck unified Germany through a series of strategic wars and diplomatic maneuvers. He fostered nationalism by leveraging conflicts with Denmark, Austria, and France, ultimately leading to the Austro-Prussian War and the Franco-Prussian War, which rallied the German states around Prussia. Bismarck's skillful manipulation of political alliances and his ability to present Prussia as the protector of German interests were crucial in consolidating the German Empire in 1871, following the defeat of France. His realpolitik approach ensured that he maintained control over the unification process while sidelining potential rivals.
