Otto Von Bismark became the first chancellor of Germany and masterminded the unification of Germany in 1871. The idea for the unification became necessary during the 16th and 17th centuries because the country remained split into city-states, different from Britain and France. Germany's city-states had its ruling king, which explained a lack of political solidarity. A sense of nationalism was coming up, and Bismark wanted to build a nation by uniting. Germany got its unification with the help of the Prussian Army and bureaucracy in 1871.
