Question: What dissolved privileges in Poland held by the empire that used Pan-Slavism as a tool, the leader of the North German Confederation during the Franco-Prussian War, and the Habsburg Monarchy?

Knowledge 1: Slavs
Pan-Slavism, a movement which came into prominence in the mid-19th century, emphasized the common heritage and unity of all the Slavic peoples. The main focus was in the Balkans where the South Slavs had been ruled for centuries by other empires: the Byzantine Empire, Austria-Hungary, the Ottoman Empire, and Venice. The Russian Empire used Pan-Slavism as a political tool; as did the Soviet Union, which gained political-military influence and control over most Slavic-majority nations between 1945 and 1948 and retained a hegemonic role until the period 1989–1991.

The Franco-Prussian War was a conflict between France and Prussia, while Prussia was backed up by the North German Confederation, of which it was a member, and the South German states of Baden, Württemberg and Bavaria. The complete Prussian and German victory brought about the final unification of Germany under King Wilhelm I of Prussia. It also marked the downfall of Napoleon III and the end of the Second French Empire, which was replaced by the Third Republic. As part of the settlement, almost all of the territory of Alsace-Lorraine was taken by Prussia to become a part of Germany, which it would retain until the end of World War I.

At the beginning of the 1930s, the Nazi Party's rise to power increased tensions between Germany and the Soviet Union along with other countries with ethnic Slavs, who were considered "Untermenschen" (inferior) according to Nazi racial ideology. Moreover, the anti-Semitic Nazis associated ethnic Jews with both communism and financial capitalism, both of which they opposed. Consequently, Nazi theory held that Slavs in the Soviet Union were being ruled by "Jewish Bolshevik" masters. In 1934, Hitler himself had spoken of an inescapable battle against both Pan-Slavism and Neo-Slavism, the victory in which would lead to "permanent mastery of the world", though he stated that they would "walk part of the road with the Russians, if that will help us." The resulting manifestation of German anti-Bolshevism and an increase in Soviet foreign debts caused German–Soviet trade to dramatically decline.[b] Imports of Soviet goods to Germany fell to 223 million Reichsmarks in 1934 as the more isolationist Stalinist regime asserted power and the abandonment of post–World War I Treaty of Versailles military controls decreased Germany's reliance on Soviet imports.[clarification needed]

The Reichstag was the Parliament of the North German Confederation (), founded after the Austro-Prussian War of 1866. It functioned until the establishment of the German Empire in 1871. Parliamentary sessions were held in the same building as the Upper House of the Prussian Landtag, the Prussian House of Lords, located at 3 Leipziger Straße in Berlin, Germany. The same location is now the home of the German Federal Bundesrat. [SEP] Knowledge 3: Modern history
