Question: When did Chopin's family move to the city where the Communist government was overthrown first?

full_context: Document 1: Cold War: By the 1970s, both sides had become interested in making accommodations in order to create a more stable and predictable international system, inaugurating a period of détente that saw Strategic Arms Limitation Talks and the US opening relations with the People's Republic of China as a strategic counterweight to the Soviet Union. Détente collapsed at the end of the decade with the beginning of the Soviet -- Afghan War in 1979. The early 1980s were another period of elevated tension, with the Soviet downing of Korean Air Lines Flight 007 (1983), and the ``Able Archer ''NATO military exercises (1983). The United States increased diplomatic, military, and economic pressures on the Soviet Union, at a time when the communist state was already suffering from economic stagnation. In the mid-1980s, the new Soviet leader Mikhail Gorbachev introduced the liberalizing reforms of perestroika (`` reorganization'', 1987) and glasnost (``openness '', c. 1985) and ended Soviet involvement in Afghanistan. Pressures for national independence grew stronger in Eastern Europe, especially Poland. Gorbachev meanwhile refused to use Soviet troops to bolster the faltering Warsaw Pact regimes as had occurred in the past. The result in 1989 was a wave of revolutions that peacefully (with the exception of the Romanian Revolution) overthrew all of the communist regimes of Central and Eastern Europe. The Communist Party of the Soviet Union itself lost control and was banned following an abortive coup attempt in August 1991. This in turn led to the formal dissolution of the USSR in December 1991 and the collapse of communist regimes in other countries such as Mongolia, Cambodia and South Yemen. The United States remained as the world's only superpower.
Document 2: Soviet Union: With the rise of strong nationalist and separatist movements inside the union republics, Gorbachev tried to avert a dissolution of the Soviet Union in the post-Cold War era. A March 1991 referendum, boycotted by some republics, resulted in a majority of participating citizens voting in favor of preserving the union as a renewed federation. Gorbachev's power was greatly diminished after Russian President Boris Yeltsin played a high - profile role in facing down an abortive August 1991 coup d'état attempted by Communist Party hardliners. On 25 December 1991, Gorbachev resigned and the remaining twelve constituent republics emerged as independent post-Soviet states. The Russian Federation -- formerly the Russian SFSR -- assumed the Soviet Union's rights and obligations and is recognized as the successor state of the Soviet Union. In summing up the international ramifications of these events, Vladislav Zubok stated: ``The collapse of the Soviet empire was an event of epochal geopolitical, military, ideological and economic significance. ''
Document 3: Dissolution of the Soviet Union: On December 7, 1989, the Communist Party of Lithuania under the leadership of Algirdas Brazauskas, split from the Communist Party of the Soviet Union and abandoned its claim to have a constitutional ``leading role ''in politics. A smaller loyalist faction of the Communist Party, headed by hardliner Mykolas Burokevičius, was established and remained affiliated with the CPSU. However, Lithuania's governing Communist Party was formally independent from Moscow's control -- a first for Soviet Republics and a political earthquake that prompted Gorbachev to arrange a visit to Lithuania the following month in a futile attempt to bring the local party back under control. The following year, the Communist Party lost power altogether in multiparty parliamentary elections which had caused Vytautas Landsbergis to become the first non-Communist president of Lithuania since its forced incorporation into the USSR.
Document 4: Frédéric Chopin: Frédéric François Chopin (/ˈʃoʊpæn/; French pronunciation: ​[fʁe.de.ʁik fʁɑ̃.swa ʃɔ.pɛ̃]; 22 February or 1 March 1810 – 17 October 1849), born Fryderyk Franciszek Chopin,[n 1] was a Polish and French (by citizenship and birth of father) composer and a virtuoso pianist of the Romantic era, who wrote primarily for the solo piano. He gained and has maintained renown worldwide as one of the leading musicians of his era, whose "poetic genius was based on a professional technique that was without equal in his generation." Chopin was born in what was then the Duchy of Warsaw, and grew up in Warsaw, which after 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.
Document 5: Frédéric Chopin: Fryderyk's father, Nicolas Chopin, was a Frenchman from Lorraine who had emigrated to Poland in 1787 at the age of sixteen. Nicolas tutored children of the Polish aristocracy, and in 1806 married Justyna Krzyżanowska, a poor relative of the Skarbeks, one of the families for whom he worked. Fryderyk was baptized on Easter Sunday, 23 April 1810, in the same church where his parents had married, in Brochów. His eighteen-year-old godfather, for whom he was named, was Fryderyk Skarbek, a pupil of Nicolas Chopin. Fryderyk was the couple's second child and only son; he had an elder sister, Ludwika (1807–55), and two younger sisters, Izabela (1811–81) and Emilia (1812–27). Nicolas was devoted to his adopted homeland, and insisted on the use of the Polish language in the household.
Document 6: Dissolution of the Soviet Union: On October 25, 1989, the Supreme Soviet voted to eliminate special seats for the Communist Party and other official organizations in national and local elections, responding to sharp popular criticism that such reserved slots were undemocratic. After vigorous debate, the 542-member Supreme Soviet passed the measure 254-85 (with 36 abstentions). The decision required a constitutional amendment, ratified by the full congress, which met December 12–25. It also passed measures that would allow direct elections for presidents of each of the 15 constituent republics. Gorbachev strongly opposed such a move during debate but was defeated.
Document 7: Dissolution of the Soviet Union: On September 10, 1987, after a lecture from hardliner Yegor Ligachev at the Politburo for allowing these two unsanctioned demonstrations in Moscow, Boris Yeltsin wrote a letter of resignation to Gorbachev, who had been holidaying on the Black Sea. Gorbachev was stunned – no one had ever voluntarily resigned from the Politburo. At the October 27, 1987, plenary meeting of the Central Committee, Yeltsin, frustrated that Gorbachev had not addressed any of the issues outlined in his resignation letter, criticized the slow pace of reform, servility to the general secretary, and opposition from Ligachev that had led to his (Yeltsin's) resignation. No one had ever addressed the Party leader so brazenly in front of the Central Committee since Leon Trotsky in the 1920s. In his reply, Gorbachev accused Yeltsin of "political immaturity" and "absolute irresponsibility." No one backed Yeltsin.
Document 8: Warsaw: One of the most famous people born in Warsaw was Maria Skłodowska-Curie, who achieved international recognition for her research on radioactivity and was the first female recipient of the Nobel Prize. Famous musicians include Władysław Szpilman and Frédéric Chopin. Though Chopin was born in the village of Żelazowa Wola, about 60 km (37 mi) from Warsaw, he moved to the city with his family when he was seven months old. Casimir Pulaski, a Polish general and hero of the American Revolutionary War, was born here in 1745.
Document 9: Frédéric Chopin: In October 1810, six months after Fryderyk's birth, the family moved to Warsaw, where his father acquired a post teaching French at the Warsaw Lyceum, then housed in the Saxon Palace. Fryderyk lived with his family in the Palace grounds. The father played the flute and violin; the mother played the piano and gave lessons to boys in the boarding house that the Chopins kept. Chopin was of slight build, and even in early childhood was prone to illnesses.
Document 10: Revolutions of 1989: The events of the full - blown revolution began in Poland in 1989 and continued in Hungary, East Germany, Bulgaria, Czechoslovakia and Romania. One feature common to most of these developments was the extensive use of campaigns of civil resistance, demonstrating popular opposition to the continuation of one - party rule and contributing to the pressure for change. Romania was the only Eastern Bloc country whose people overthrew its Communist regime violently. Protests in Tiananmen Square (April to June 1989) failed to stimulate major political changes in China, but influential images of courageous defiance during that protest helped to precipitate events in other parts of the globe. On 4 June 1989 the trade union Solidarity won an overwhelming victory in a partially free election in Poland, leading to the peaceful fall of Communism in that country in the summer of 1989. Hungary began (June 1989) dismantling its section of the physical Iron Curtain, leading to a exodus of East Germans through Hungary, which destabilised East Germany. This led to mass demonstrations in cities such as Leipzig and subsequently to the fall of the Berlin Wall in November 1989, which served as the symbolic gateway to German reunification in 1990.
Document 11: Frédéric Chopin: In 1827, soon after the death of Chopin's youngest sister Emilia, the family moved from the Warsaw University building, adjacent to the Kazimierz Palace, to lodgings just across the street from the university, in the south annex of the Krasiński Palace on Krakowskie Przedmieście,[n 5] where Chopin lived until he left Warsaw in 1830.[n 6] Here his parents continued running their boarding house for male students; the Chopin Family Parlour (Salonik Chopinów) became a museum in the 20th century. In 1829 the artist Ambroży Mieroszewski executed a set of portraits of Chopin family members, including the first known portrait of the composer.[n 7]
Document 12: Frédéric Chopin: Two Polish friends in Paris were also to play important roles in Chopin's life there. His fellow student at the Warsaw Conservatory, Julian Fontana, had originally tried unsuccessfully to establish himself in England; Albert Grzymała, who in Paris became a wealthy financier and society figure, often acted as Chopin's adviser and "gradually began to fill the role of elder brother in [his] life." Fontana was to become, in the words of Michałowski and Samson, Chopin's "general factotum and copyist".
Document 13: Dissolution of the Soviet Union: On July 1, 1988, the fourth and last day of a bruising 19th Party Conference, Gorbachev won the backing of the tired delegates for his last-minute proposal to create a new supreme legislative body called the Congress of People's Deputies. Frustrated by the old guard's resistance, Gorbachev embarked on a set of constitutional changes to try to separate party and state, and thereby isolate his conservative Party opponents. Detailed proposals for the new Congress of People's Deputies were published on October 2, 1988, and to enable the creation of the new legislature the Supreme Soviet, during its November 29–December 1, 1988, session, implemented amendments to the 1977 Soviet Constitution, enacted a law on electoral reform, and set the date of the election for March 26, 1989.
Document 14: Dissolution of the Soviet Union: Spring 1989 saw the people of the Soviet Union exercising a democratic choice, albeit limited, for the first time since 1917, when they elected the new Congress of People's Deputies. Just as important was the uncensored live TV coverage of the legislature's deliberations, where people witnessed the previously feared Communist leadership being questioned and held accountable. This example fueled a limited experiment with democracy in Poland, which quickly led to the toppling of the Communist government in Warsaw that summer – which in turn sparked uprisings that overthrew communism in the other five Warsaw Pact countries before the end of 1989, the year the Berlin Wall fell. These events showed that the people of Eastern Europe and the Soviet Union did not support Gorbachev's drive to modernize Communism; rather, they preferred to abandon it altogether.
Document 15: 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.
