Otto Eduard Leopold, Prince of Bismarck, Count of Bismarck-Schönhausen, Duke of Lauenburg (1 April 1815 – 30 July 1898), was a German statesman and diplomat who oversaw the unification of Germany and served as its first chancellor from 1871 to 1890. Bismarck's Realpolitik and firm governance earned him the nickname Iron Chancellor (Eiserner Kanzler). From Junker landowner origins, Bismarck rose rapidly in Prussian politics under King Wilhelm I of Prussia. He served as the Prussian ambassador to Russia and France and in both houses of the Prussian parliament. From 1862 to 1890, he held office as the minister president and foreign minister of Prussia. Under Bismarck's leadership, Prussia provoked three short, decisive wars against Denmark, Austria, and France. After Austria's defeat in 1866, he replaced the German Confederation with the North German Confederation, which aligned the smaller North German states with Prussia while excluding Austria. In 1870, Bismarck secured France's defeat with support from the independent South German states before overseeing the creation of a unified German Empire under Prussian rule. Following Germany's unification, he was given the aristocratic title Prince of Bismarck (Fürst von Bismarck). From 1871 onwards, his balance-of-power approach to diplomacy helped maintain Germany's position in a peaceful Europe. While averse to maritime colonialism, Bismarck acquiesced to elite and popular opinion by acquiring colonies. As part of his domestic political maneuvering, Bismarck created the first welfare state, with the goal of undermining his socialist opponents. In the 1870s, he allied himself with the low-tariff, anti-Catholic Liberals and fought the Catholic Church, in what was called the Kulturkampf (lit. 'culture struggle'). This was unsuccessful, with the Catholics responding by forming the powerful German Centre Party and using universal male suffrage to gain a bloc of seats. Bismarck responded by ending the Kulturkampf, breaking with the Liberals and forming a political alliance with the Centre Party to fight the Socialists. Under his direction, the Imperial Reichstag was sidelined and did not control government policy. A staunch monarchist, Bismarck ruled autocratically through a strong bureaucracy with power concentrated in the hands of the Junker elite. After being dismissed from office by Wilhelm II, he retired to write his memoirs. Bismarck is most famous for his role in German unification. During the German Imperial period, he became a hero to German nationalists, who built monuments honouring him. Historians praise him as a visionary who kept the peace in Europe through diplomacy. However, he has been criticized for his domestic policies, such as his persecution of Catholics, as well as his authoritarian rule in general as Chancellor.
