How did otto van bismark argue with the German states should be unified?

Otto Von Bismarck argued for the unification of German states through a pragmatic approach known as "realpolitik," emphasizing the importance of power and practical considerations over ideology. He believed that a strong, unified Germany would enhance national strength and security, and he often used strategic wars, such as those against Denmark, Austria, and France, to rally support for unification. Bismarck also promoted the idea of a common German identity, fostering nationalism among the various states to create a sense of solidarity. Ultimately, he sought to unify Germany under Prussian leadership, minimizing the influence of Austria and other rival states.
