Question: The first leader of Europe's largest country, following the collapse of the union of republics that was formed as a result of the Russian revolution, died in what city?

<P0-S0> The Russian Revolution was a pair of revolutions in Russia in 1917 which dismantled the Tsarist autocracy and led to the rise of the Soviet Union. <P0-S1> The Russian Empire collapsed with the abdication of Emperor Nicholas II and the old regime was replaced by a provisional government during the first revolution of February 1917 (March in the Gregorian calendar; the older Julian calendar was in use in Russia at the time). <P0-S2> Alongside it arose grassroots community assemblies (called 'soviets') which contended for authority. <P0-S3> In the second revolution that October, the Provisional Government was toppled and all power was given to the soviets. <SEP> <P1-S0> Prior to the dissolution of the Soviet Union, Boris Yeltsin had been elected President of Russia in June 1991 in the first direct presidential election in Russian history. <P1-S1> This ensured that Yeltsin would be the political leader of the Russian successor state following dissolution. <P1-S2> This situation resulted in political turmoil as the Soviet and Russian leadership wrestled for control, which culminated in the 1991 August Putsch, where the Soviet military attempted to overthrow Gorbachev. <P1-S3> Although the coup was ultimately averted, this situation contributed to rising instability in the Soviet Union. <P1-S4> By October 1991, as the USSR was on the verge of collapse, Yeltsin announced that Russia would proceed with radical reforms, including market - oriented reform along the lines of Poland's ``big bang '', also known as`` shock therapy''. <SEP> <P2-S0> Rank Country Area (km2) Notes Russia * 3,972,400 17,098,242 including North Asia Ukraine 603,628 This includes Crimea France * 551,394 643,801 when the overseas departments are included Spain * 498,468 505,992 when the Canary Islands, Ceuta and Melilla are included Sweden 449,964 6 Norway 385,178 This includes Svalbard and Jan Mayen 7 Germany 357,168 8 Finland 338,145 9 Poland 312,685 10 Italy 301,338 11 United Kingdom 248,532 1,976,102 when the British Overseas Territories are included. <P2-S1> 12 Romania 238,392 13 Belarus 207,600 14 Kazakhstan * 180,000 (est.) <P2-S2> 2,724,902 including Asian part 15 Greece 131,940 16 Bulgaria 110,994 17 Iceland 102,775 18 Hungary 93,030 19 Portugal 91,568 20 Austria 83,858 21 Czech Republic 78,866 22 Serbia 77,453 This excludes Kosovo 23 Ireland 70,273 24 Lithuania 65,300 25 Latvia 64,589 26 Croatia 56,594 27 Bosnia and Herzegovina 51,129 28 Slovakia 49,036 29 Estonia 45,339 30 Denmark 44,493 This includes Faroe Islands;
