Who is responsible for the unification of Germany

The unification of Germany was primarily led by Otto von Bismarck, who was the Chancellor of the Kingdom of Prussia. Bismarck used a combination of diplomacy, military force, and political maneuvering to unify the various German states into one nation. The process culminated in the Franco-Prussian War of 1870-1871, which resulted in the defeat of France and the proclamation of the German Empire in 1871.
