Question: Who was in charge of the country where the performer of the Alice Polka in honor of Princess Alice was a citizen?

full_context: Document 1: Buckingham Palace: Widowed in 1861, the grief-stricken Queen withdrew from public life and left Buckingham Palace to live at Windsor Castle, Balmoral Castle and Osborne House. For many years the palace was seldom used, even neglected. In 1864, a note was found pinned to the fence of Buckingham Palace, saying: "These commanding premises to be let or sold, in consequence of the late occupant's declining business." Eventually, public opinion forced the Queen to return to London, though even then she preferred to live elsewhere whenever possible. Court functions were still held at Windsor Castle, presided over by the sombre Queen habitually dressed in mourning black, while Buckingham Palace remained shuttered for most of the year.
Document 2: Southern Europe: The Nazi regime under Adolf Hitler came to power in 1933, and along with Mussolini's Italy sought to gain control of the continent by the Second World War. Following the Allied victory in the Second World War, Europe was divided by the Iron Curtain. The countries in Southeastern Europe were dominated by the Soviet Union and became communist states. The major non-communist Southern European countries joined a US-led military alliance (NATO) and formed the European Economic Community amongst themselves. The countries in the Soviet sphere of influence joined the military alliance known as the Warsaw Pact and the economic bloc called Comecon. Yugoslavia was neutal.
Document 3: Frédéric Chopin: In 1817 the Saxon Palace was requisitioned by Warsaw's Russian governor for military use, and the Warsaw Lyceum was reestablished in the Kazimierz Palace (today the rectorate of Warsaw University). Fryderyk and his family moved to a building, which still survives, adjacent to the Kazimierz Palace. During this period, Fryderyk was sometimes invited to the Belweder Palace as playmate to the son of the ruler of Russian Poland, Grand Duke Constantine; he played the piano for the Duke and composed a march for him. Julian Ursyn Niemcewicz, in his dramatic eclogue, "Nasze Przebiegi" ("Our Discourses", 1818), attested to "little Chopin's" popularity.
Document 4: Austria: Karl Renner and Adolf Schärf (Socialist Party of Austria [Social Democrats and Revolutionary Socialists]), Leopold Kunschak (Austria's People's Party [former Christian Social People's Party]), and Johann Koplenig (Communist Party of Austria) declared Austria's secession from the Third Reich by the Declaration of Independence on 27 April 1945 and set up a provisional government in Vienna under state Chancellor Renner the same day, with the approval of the victorious Red Army and backed by Joseph Stalin. (The date is officially named the birthday of the second republic.) At the end of April, most of western and southern Austria were still under Nazi rule. On 1 May 1945, the federal constitution of 1929, which had been terminated by dictator Dollfuss on 1 May 1934, was declared valid again.

Document 6: Buckingham Palace: Court presentations of aristocratic young ladies to the monarch took place at the palace from the reign of Edward VII. These young women were known as débutantes, and the occasion—termed their "coming out"—represented their first entrée into society. Débutantes wore full court dress, with three tall ostrich feathers in their hair. They entered, curtsied, and performed a choreographed backwards walk and a further curtsy, while manoeuvring a dress train of prescribed length. (The ceremony, known as an evening court, corresponded to the "court drawing rooms" of Victoria's reign.) After World War II, the ceremony was replaced by less formal afternoon receptions, usually without choreographed curtsies and court dress.

Strauss II, F. Lehár, C.M. Ziehrer, among others. Their concerts also always include performances by ballet dancers and opera singers.
Document 11: Frédéric Chopin: In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (£1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.
Document 12: Buckingham Palace: Before Prince Albert's death, the palace was frequently the scene of musical entertainments, and the greatest contemporary musicians entertained at Buckingham Palace. The composer Felix Mendelssohn is known to have played there on three occasions. Johann Strauss II and his orchestra played there when in England. Strauss's "Alice Polka" was first performed at the palace in 1849 in honour of the queen's daughter, Princess Alice. Under Victoria, Buckingham Palace was frequently the scene of lavish costume balls, in addition to the usual royal ceremonies, investitures and presentations.
Document 13: Classical period (music): However, Vienna's fall as the most important musical center for orchestral composition during the late 1820s, precipitated by the deaths of Beethoven and Schubert, marked the Classical style's final eclipse -- and the end of its continuous organic development of one composer learning in close proximity to others. Franz Liszt and Frédéric Chopin visited Vienna when they were young, but they then moved on to other cities. Composers such as Carl Czerny, while deeply influenced by Beethoven, also searched for new ideas and new forms to contain the larger world of musical expression and performance in which they lived.
Document 14: Azerbaijan People's Government: The Firqah-i Dimukrat, or Azerbaijani Democratic Party (ADP), publicly announced its formation in Tabriz on September 3, 1945 by a group of veteran communists headed by Ja'far Pishevari. After the announcement, the communist, Soviet-supported Tudeh party dissolved its Azerbaijan chapter and ordered its members to join ADP. ADP expanded throughout Iranian Azerbaijan, and initiated a local coup d'état with help from Soviet army, who prevented the Iranian army from intervening. During the first week of September 1945, the Azerbaijani Democratic Party, led by Ja'far Pishevari, a long-time leader of the revolutionary movement in Gilan, declared itself to be in control of Iranian Azerbaijan, promised liberal democratic reforms, and disbanded the local branch of Tudeh. Later in September 1945, at its first congress, the Azerbaijani Democratic Party authorized the formation of a peasant's militia. This militia started a bloodless coup on November 18, 1945 and by November 21, 1945 they had captured all remaining government posts in the province, and Iranian Azerbaijan "became an autonomous republic under the direction of a 39-member national executive committee".  The reality of the power seems to have been exercised by Mohammed Biriya, the Minister of Propaganda and head of the local secret police.At the same time, the US was steadily increasing its military assistance to the Iranian government. Under pressure by the Western powers, the Soviet Union revoked its support of the newly created state and the Iranian military succeeded in re-establishing Iranian rule in November 1946. According to Tadeusz Swietochowski:
Document 15: Austria: After general elections held in October 2006, the Social Democratic Party (SPÖ) emerged as the strongest party, and the Austrian People's Party (ÖVP) came in second, having lost about 8% of its previous polling. Political realities prohibited any of the two major parties from forming a coalition with smaller parties. In January 2007 the People's Party and SPÖ formed a grand coalition with the social democrat Alfred Gusenbauer as Chancellor. This coalition broke up in June 2008.
