What is Otto von Bismarck method for uniting Germany?

Otto Von Bismarck's method for uniting Germany involved a strategy known as "Realpolitik," which emphasized practical and pragmatic approaches over ideological considerations. He orchestrated a series of wars, including the Danish War, the Austro-Prussian War, and the Franco-Prussian War, to isolate Austria and France, thereby rallying the German states around Prussia. Through diplomacy and military strength, Bismarck ultimately succeeded in consolidating German territories under Prussian leadership, leading to the proclamation of the German Empire in 1871.
