Otto Eduard Leopold von Bismarck (1 April 1815 – 30 July 1898) was a German-Prussian statesman of the late 19th century, and a dominant figure in world affairs. As Ministerpräsident, or Prime Minister, of Prussia from 1862–1890, he oversaw the unification of Germany. In 1867 he became Chancellor of the North German Confederation. He designed the German Empire in 1871, becoming its first Chancellor and dominating its affairs until he was removed by Wilhelm II in 1890. His diplomacy of Realpolitik and powerful rule gained him the nickname "The Iron Chancellor".
After his death German nationalists made Bismarck their hero, building hundreds of monuments glorifying the symbol of powerful personal leadership. Historians praised him as a statesman of moderation and balance who was primarily responsible for the unification of the German states into a nation-state. He used balance-of-power diplomacy to keep Europe peaceful in the 1870s and 1880s. He created a new nation with a progressive social policy, a result that went beyond his initial goals as a practitioner of power politics in Prussia. Bismarck, a devout Lutheran who was loyal to his king, promoted government through a strong, well-trained bureaucracy with a hereditary monarchy at the top.
Bismarck had recognized early in his political career that the opportunities for national unification would exist and he worked successfully to provide a Prussian structure to the nation as a whole. However, his Reich of 1871 deliberately restricted democracy, and the anti-Catholic and anti-Socialist legislation that he introduced unsuccessfully in the 1870s and 1880s left a devastating legacy of distrust and fragmentation in German political culture.
