<P> Heinrich von Treitschke's History of Germany in the Nineteenth Century, published in 1879, has perhaps a misleading title: it privileges the history of Prussia over the history of other German states, and it tells the story of the German - speaking peoples through the guise of Prussia's destiny to unite all German states under its leadership . The creation of this Borussian myth (Borussia is the Latin name for Prussia) established Prussia as Germany's savior; it was the destiny of all Germans to be united, this myth maintains, and it was Prussia's destiny to accomplish this . According to this story, Prussia played the dominant role in bringing the German states together as a nation - state; only Prussia could protect German liberties from being crushed by French or Russian influence . The story continues by drawing on Prussia's role in saving Germans from the resurgence of Napoleon's power in 1815, at Waterloo, creating some semblance of economic unity, and uniting Germans under one proud flag after 1871 . </P> <P> Mommsen's contributions to the Monumenta Germaniae Historica laid the groundwork for additional scholarship on the study of the German nation, expanding the notion of "Germany" to mean other areas beyond Prussia . A liberal professor, historian, and theologian, and generally a titan among late 19th - century scholars, Mommsen served as a delegate to the Prussian House of Representatives from 1863--1866 and 1873--1879; he also served as a delegate to the Reichstag from 1881--1884, for the liberal German Progress Party (Deutsche Fortschrittspartei) and later for the National Liberal Party . He opposed the antisemitic programs of Bismarck's Kulturkampf and the vitriolic text that Treitschke often employed in the publication of his Studien über die Judenfrage (Studies of the Jewish Question), which encouraged assimilation and Germanization of Jews . </P>
