How did Bismarck use war to strengthen pruissa?

Otto Von Bismarck strategically used war to strengthen Prussia by engaging in conflicts that fostered nationalism and unified the German states under Prussian leadership. The wars against Denmark (1864), Austria (1866), and France (1870-1871) not only expanded Prussian territory but also rallied German sentiment around a common cause. By successfully orchestrating these wars, Bismarck was able to consolidate power, increase Prussian influence, and ultimately facilitate the unification of Germany in 1871, establishing Prussia as a dominant force in the newly formed German Empire.
