among Richard Wagner and the Brothers Grimm. Writers such as Friedrich List and Paul Anton Lagarde argued for German hegemony in Central and Eastern Europe, where German domination in some areas had begun as early as the 9th century AD with the Ostsiedlung, Germanic expansion into Slavic and Baltic lands. For the Pan-Germanists, this movement was seen as a Drang nach Osten, in which Germans would be naturally inclined to seek Lebensraum by moving eastwards to reunite with the German minorities there. The Deutschlandlied ("Song of Germany"), written in 1841 by Hoffmann von Fallersleben, in its first stanza defines Deutschland as reaching "From the Meuse to the Memel / From the Adige to the Belt", i.e. as including East Prussia and South Tyrol. Reflecting upon the First Schleswig War in 1848, Karl Marx noted in 1853 that "by quarrelling amongst themselves, instead of confederating, Germans and Scandinavians, both of them belonging to the same great race, only prepare the way for their hereditary enemy, the Slav." The German Question By the 1860s Prussia and Austria had become the two most powerful states dominated by German-speaking elites. Both sought to expand their influence and territory. The Austrian Empire—like the Holy Roman Empire—was a multi-ethnic state, but the German-speaking people there did not have an absolute numerical majority; its re-shaping into the Austro-Hungarian Empire was one result of the growing nationalism of other ethnicities—especially the Hungarians. Under Prussian leadership, Otto von Bismarck would ride on the coat-tails of nationalism to unite all of the northern German lands. After Bismarck excluded Austria and the German Austrians from Germany in the German war of 1866 and (following a few other events over the next few years), the unification of Germany, established the Prussian-dominated German Empire in 1871 with the proclamation of Wilhelm I as head of a union of German-speaking states, while disregarding millions of its non-German subjects who desired self-determination from German rule. After World War I the Pan-Germanist philosophy changed drastically during Adolf Hitler's rise to power. Pan-Germanists originally sought to unify all the German-speaking populations of Europe in a single nation-state known as Großdeutschland (Greater Germany), where "German-speaking" was sometimes taken as synonymous with Germanic-speaking, to the inclusion of the Frisian- and Dutch-speaking populations of the Low Countries, and Scandinavia. Although Bismarck had excluded Austria and the German Austrians from his creation of the Kleindeutschland state in 1871, integrating the German
