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?

<P0-S0> Pan-Slavism, a movement which came into prominence in the mid-19th century, emphasized the common heritage and unity of all the Slavic peoples. <P0-S1> 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. <P0-S2> 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. <SEP> <P1-S0> in 1870, after france attacked prussia, prussia and its new allies in southern germany (among them bavaria) were victorious in the franco-prussian war. <P1-S1> it created the german empire in 1871 as a german nation-state, effectively excluding the multi-ethnic austrian habsburg monarchy and liechtenstein. <P1-S2> integrating the austrians nevertheless remained a strong desire for many people of germany and austria, especially among the liberals, the social democrats and also the catholics who were a minority within the protestant germany. <SEP> <P2-S0> federalism has a long tradition in german history. <P2-S1> the holy roman empire comprised many petty states numbering more than 300 around 1796. the number of territories was greatly reduced during the napoleonic wars (1796–1814). <P2-S2> after the congress of vienna (1815), 39 states formed the german confederation. <P2-S3> the confederation was dissolved after the austro-prussian war and replaced by a north german federation under prussian hegemony; this war left prussia dominant in germany, and german nationalism would compel the remaining independent states to ally with prussia in the franco-prussian war of 1870–71, and then to accede to the crowning of king wilhelm of prussia as german emperor. <P2-S4> the new german empire included 25 states (three of them, hanseatic cities) and the imperial territory of alsace-lorraine. <P2-S5> the empire was dominated by prussia, which controlled 65% of the territory and 62% of the population. <P2-S6> after the territorial losses of the treaty of versailles, the remaining states continued as republics of a new german federation. <P2-S7> these states were gradually de facto abolished and reduced to provinces under the nazi regime via the gleichschaltung process, as the states administratively were largely superseded by the nazi gau system. <SEP> <P3-S0> Poland's nobility were also more numerous than those of all other European countries, constituting some 10–12% of the total population of historic Polish–Lithuanian Commonwealth also some 10–12% among ethnic Poles on ethnic Polish lands (part of Commonwealth), but up to 25% of all Poles worldwide (szlachta could dispose more of resources to travels and/or conquering), while in some poorer regions (e.g., Mazowsze, the area centred on Warsaw) nearly 30%. <P3-S1> However, according to  szlachta comprised around 8% of the total population in 1791 (up from 6.6% in the 16th century), and no more than 16% of the Roman Catholic (mostly ethnically Polish) population. <P3-S2> It should be noted, though, that Polish szlachta usually incorporated most local nobility from the areas that were absorbed by Poland–Lithuania (Ruthenian boyars, Livonian nobles, etc.) <P3-S3> By contrast, the nobilities of other European countries, except for Spain, amounted to a mere 1–3%, however the era of sovereign rules of Polish nobility ended earlier than in other countries (excluding France) yet in 1795 (see: Partitions of Poland), since then their legitimation and future fate depended on legislature and procedures of Russian Empire, Kingdom of Prussia or Habsburg Monarchy. <P3-S4> Gradually their privileges were under further limitations to be completely dissolved by March Constitution of Poland in 1921. <SEP> <P4-S0> The Franco-Prussian War or Franco-German War (German: Deutsch-Französischer Krieg, lit. <P4-S1> German-French War, French: Guerre franco-allemande, lit. <P4-S2> Franco-German War), often referred to in France as the War of 1870 (19 July 1870 – 10 May 1871), was a conflict between the Second French Empire and the German states of the North German Confederation led by the Kingdom of Prussia. <P4-S3> The conflict was caused by Prussian ambitions to extend German unification. <P4-S4> Some historians argue that the Prussian chancellor Otto von Bismarck planned to provoke a French attack in order to draw the southern German states—Baden, Württemberg, Bavaria and Hesse-Darmstadt—into an alliance with the North German Confederation dominated by Prussia, while others contend that Bismarck did not plan anything and merely exploited the circumstances as they unfolded.
