full_context: Document 1: 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.
Document 2: 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.

Document 4: 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.

Document 10: Johann Strauss III: Despite his keen interest in composing, he was better remembered as a conductor. His only stage work, the three-act operetta "Katze und Maus", composed in 1898, premiered in Vienna on 23 December 1898, at the Theater an der Wien. Its public reaction bordered on utter dislike, and music critics called for the distraught composer to reassess himself and to appear under a pseudonym, in order not to tarnish the name of his famous relatives. He salvaged the music score and produced independent pieces of which the waltzes "Sylvanien", Op. 1 and "Leonie", Op. 2 survived obscurity.
Document 11: 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.

The dance hall is newly hung throughout with red and gold drapery, the ceiling very tastefully prepared. Little statues, surrounded by flowers and leaves, heighten the appeal of the decorations. The music was personally conducted by Strauss and his waltz 'Paroxysmen', written especially for this ball, belongs to his best compositions."
