Question: What dissolved the privileges in Poland of the empire where Tamar Abakelia was from, the Kingdom that acquired some Thuringian territory in 1815, and the Habsburg Monarchy?

Knowledge 1: Tamar Abakelia
Born in Khoni, Imereti (then part of Kutais Governorate, Russian Empire), Tamar Abakelia graduated from Tbilisi State Academy of Arts in 1929 and taught there beginning in 1938. Among Abakelia’s works were graphic illustrations for Nikolay Tikhonov, Shota Rustaveli, "David of Sasun", Vazha-Pshavela as well as stage decorations for the Rustaveli and Marjanishvili theaters and costume designs for the films "Arsena" (1937), "Giorgi Saakadze" (1942), and "David Guramishvili" (1945). Many of her achievements were in the field of sculpture. Noted for the dynamism of composition and artistically rounded forms, Abakelia was responsible for much of the progress of Soviet Georgian sculpture. She sculptured friezes on the Museum of Marxism–Leninism in Tbilisi, depicting the various phases of socialist construction in Georgia (1936–37). Abakelia died in Tbilisi in 1953 and was buried there, at the Didube Pantheon. [SEP] Knowledge 2: Thuringia
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. 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. 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. In 1920, after World War I, these small states merged into one state, called Thuringia; only Saxe-Coburg voted to join Bavaria instead. Weimar became the new capital of Thuringia. The coat of arms of this new state was simpler than they had been previously. [SEP] Knowledge 3: Szlachta
During the Partitions of Poland from 1772 to 1795, its members began to lose these legal privileges and social status. From that point until 1918, the legal status of the nobility was essentially dependent upon the policies of the three partitioning powers: the Russian Empire, the Kingdom of Prussia, and the Habsburg Monarchy. The legal privileges of the szlachta were legally abolished in the Second Polish Republic by the March Constitution of 1921.

The Province of Prussia (; ) was a province of Prussia from 1829 to 1878. Prussia was established as a province of the Kingdom of Prussia in 1829 from the provinces of East Prussia and West Prussia, and was dissolved in 1878 when the merger was reversed. [SEP] Knowledge 3: Tamar Abakelia
