Otto Von Bismarck was a German statesman who played a crucial role in unifying Germany in the 19th century. Born in 1815, he became the first Chancellor of the German Empire in 1871. Bismarck was known for his clever political strategies, often using diplomacy and alliances to achieve his goals. He believed in the idea of "Realpolitik," which emphasized practical and pragmatic approaches to politics rather than idealistic ones. Bismarck's leadership helped to strengthen Germany and establish it as a major European power. He is also famous for his social reforms, including the introduction of health insurance and pensions, which laid the groundwork for the modern welfare state. His legacy continues to influence German politics today.
