Question: What dissolved the privileges of the empire using Pan-Slavism as a political tool, the kingdom acquiring some Thuringian territory or Habsburg Monarchy?

<P0-S0> because of the vastness and diversity of the territory occupied by slavic people, there were several centers of slavic consolidation. <P0-S1> in the 19th century, pan-slavism developed as a movement among intellectuals, scholars, and poets, but it rarely influenced practical politics and did not find support in some nations that had slavic origins. <P0-S2> pan-slavism became compromised when the russian empire started to use it as an ideology justifying its territorial conquests in central europe as well as subjugation of other ethnic groups of slavic origins such as poles and ukrainians, and the ideology became associated with russian imperialism. <P0-S3> the common slavic experience of communism combined with the repeated usage of the ideology by soviet propaganda after world war ii within the eastern bloc (warsaw pact) was a forced high-level political and economic hegemony of the ussr dominated by russians. <P0-S4> a notable political union of the 20th century that covered most south slavs was yugoslavia, but it ultimately broke apart in the 1990s along with the soviet union. <SEP> <P1-S0> a region of moldavia during the middle ages, the territory of what became known as bukovina was, from 1774 to 1918, an administrative division of the habsburg monarchy, the austrian empire, and austria-hungary. <P1-S1> after world war i, romania established its control over bukovina. <P1-S2> in 1940, the northern half of bukovina was annexed by the soviet union in violation of the molotov–ribbentrop pact, and currently is part of ukraine. <SEP> <P2-S0> Some reordering of the Thuringian states occurred during the German Mediatisation from 1795 to 1814, and the territory was included within the Napoleonic Confederation of the Rhine organized in 1806. <P2-S1> The 1815 Congress of Vienna confirmed these changes and the Thuringian states' inclusion in the German Confederation; the Kingdom of Prussia also acquired some Thuringian territory and administered it within the Province of Saxony. <P2-S2> The Thuringian duchies which became part of the German Empire in 1871 during the Prussian-led unification of Germany were Saxe-Weimar-Eisenach, Saxe-Meiningen, Saxe-Altenburg, Saxe-Coburg-Gotha, Schwarzburg-Sondershausen, Schwarzburg-Rudolstadt and the two principalities of Reuss Elder Line and Reuss Younger Line. <P2-S3> In 1920, after World War I, these small states merged into one state, called Thuringia; only Saxe-Coburg voted to join Bavaria instead. <P2-S4> Weimar became the new capital of Thuringia. <P2-S5> The coat of arms of this new state was simpler than they had been previously. <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> Gradually their privileges were under further limitations to be completely dissolved by March Constitution of Poland in 1921. <P3-S2> 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-S3> 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-S4> 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. <SEP> <P4-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. <P4-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. <P4-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.
