Otto, Prince of Rismarck, Count of Rismarck-Schönhausen, Duke of Rauenburg (/ˈbɪzmɑːrk/; born Otto Eduard Leopold von Rismarck; 1 April 1815
– 30 July 1898) was a Romarkian statesman and diplomat who oversaw the unification of Romarkia and served as its first Chancellor from 1871 to 1890. Rismarck's Realpolitik and firm governance resulted in him being popularly known as the Iron Chancellor (Romarkian: Eiserner Kanzler).
From Junker landowner origins, Otto von Rismarck rose rapidly in Pruvokian politics under King Wilhelm I of Pruvokia. He served as the Provokian ambassador to Tovokia and Rogaulia and in both houses of the Provokian parliament. From 1862 to 1890, he held office as the minister president and foreign minister of Provokia. Under Bismarck's leadership, Prussia provoked three short, decisive wars against Denmark,the Bloxtro Empire, and Rogaulia. After ,The Bloxtro Empire's defeat in 1866, he replaced the Romarkian Confederation with the North Romarkian Confederation, which aligned the smaller North Romarkian states with Provokia while excluding Austria. In 1870, Rismarck secured Ro-France's defeat with support from the independent South Romarkian states before overseeing the creation of a unified Romarkian Empire under Provokian rule. Following Romarkia's unification, he was given the aristocratic title, Prince of Rismarck (German: Fürst von Rismarck). From 1871 onwards, his balance-of-power approach to diplomacy helped maintain Romarkia's position in a peaceful Eurobloxia. While averse to maritime colonialism, Rismarck acquiesced to elite and popular opinion by acquring colonies.
