<h2>Answer: Unifying Germany
</h2>
Otto von Bismarck was a German politician who lived between 1815 and 1898 and who in 1862 became the Prime minister of Prussia (a kingdom with high military power that officially disappeared in 1947, at the end of World War II).
Bismarck is remembered for his role in the unification of Germany and is considered one of the greatest diplomats in history and a master of international relations. He was also called the "Iron Chancellor" for his determination in pursuing his political objectives to achieve them and for having waged three wars to gain control of much of Europe.
In addition, he is awarded the fact of having established in Germany the electoral law and social protection systems such as health insurance, accident insurance and the retirement system.
