Document 2: October Revolution: It followed and capitalized on the February Revolution of the same year, which overthrew the Tsarist autocracy and resulted in a provisional government after a transfer of power proclaimed by Grand Duke Michael, brother of Tsar Nicolas II, who declined to take power after the Tsar stepped down. During this time, urban workers began to organize into councils (soviets) wherein revolutionaries criticized the provisional government and its actions. After the Congress of Soviets, now the governing body, had its second session, it elected members of the Bolsheviks and other leftist groups such as the Left Socialist Revolutionaries to important positions within the new state of affairs. This immediately initiated the establishment of the Russian Socialist Federative Soviet Republic, the world's first self - proclaimed socialist state. On 17 July 1918, the Tsar and his family were executed.

Document 5: History of Russia: Alexander was succeeded by his son Nicholas II (1894–1917). The Industrial Revolution, which began to exert a significant influence in Russia, was meanwhile creating forces that would finally overthrow the tsar. Politically, these opposition forces organized into three competing parties: The liberal elements among the industrial capitalists and nobility, who believed in peaceful social reform and a constitutional monarchy, founded the Constitutional Democratic party or Kadets in 1905. Followers of the Narodnik tradition established the Socialist-Revolutionary Party or Esers in 1901, advocating the distribution of land among those who actually worked it—the peasants. A third radical group founded the Russian Social Democratic Labour Party or RSDLP in 1898; this party was the primary exponent of Marxism in Russia. Gathering their support from the radical intellectuals and the urban working class, they advocated complete social, economic and political revolution.
Document 6: List of Russian monarchs: The Time of Troubles came to a close with the election of Michael Romanov as Tsar in 1613. Michael officially reigned as Tsar, though his father, the Patriarch Philaret (died 1633) initially held the real power. However, Michael's descendents would rule Russia, first as Tsars and later as Emperors, until the Russian Revolution of 1917. Peter the Great (reigned 1682 - 1725), a grandson of Michael Romanov, reorganized the Russian state along more Western lines, establishing the Russian Empire in 1721.
Document 7: High-definition television: In 1958, the Soviet Union developed Тransformator (Russian: Трансформатор, meaning Transformer), the first high-resolution (definition) television system capable of producing an image composed of 1,125 lines of resolution aimed at providing teleconferencing for military command. It was a research project and the system was never deployed by either the military or consumer broadcasting.
Document 8: 3D television: Stereoscopic 3D television was demonstrated for the first time on 10 August 1928, by John Logie Baird in his company's premises at 133 Long Acre, London. Baird pioneered a variety of 3D television systems using electro - mechanical and cathode - ray tube techniques. The first 3D TV was produced in 1935, and stereoscopic 3D still cameras for personal use had already become fairly common by the Second World War. Many 3D movies were produced for theatrical release in the US during the 1950s just when television started to become popular. The first such movie was Bwana Devil from United Artists that could be seen all across the US in 1952. One year later, in 1953, came the 3D movie House of Wax which also featured stereophonic sound. Alfred Hitchcock produced his film Dial M for Murder in 3D, but for the purpose of maximizing profits the movie was released in 2D because not all cinemas were able to display 3D films. In 1946 the Soviet Union also developed 3D films, with Robinzon Kruzo being its first full - length 3D movie. People were excited to view the 3D movies, but were put off by their poor quality. Because of this, their popularity declined quickly. There was another attempt in the 1970s and 80s to make 3D movies more mainstream with the releases of Friday the 13th Part III (1982) and Jaws 3 - D (1983). 3D showings became more popular throughout the 2000s, culminating in the success of 3D presentations of Avatar in December 2009 and January 2010.

Document 10: Modern history: The Russian Civil War was a multi-party war that occurred within the former Russian Empire after the Russian provisional government collapsed and the Soviets under the domination of the Bolshevik party assumed power, first in Petrograd (St. Petersburg) and then in other places. In the wake of the October Revolution, the old Russian Imperial Army had been demobilized; the volunteer-based Red Guard was the Bolsheviks' main military force, augmented by an armed military component of the Cheka, the Bolshevik state security apparatus. There was an instituted mandatory conscription of the rural peasantry into the Red Army. Opposition of rural Russians to Red Army conscription units was overcome by taking hostages and shooting them when necessary in order to force compliance. Former Tsarist officers were utilized as "military specialists" (voenspetsy), taking their families hostage in order to ensure loyalty. At the start of the war, three-fourths of the Red Army officer corps was composed of former Tsarist officers. By its end, 83% of all Red Army divisional and corps commanders were ex-Tsarist soldiers.
Document 11: Modern history: The Russian Revolution is the series of revolutions in Russia in 1917, which destroyed the Tsarist autocracy and led to the creation of the Soviet Union. Following the abdication of Nicholas II of Russia, the Russian Provisional Government was established.

Document 13: Russian Revolution: 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. 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). Alongside it arose grassroots community assemblies (called 'soviets') which contended for authority. In the second revolution that October, the Provisional Government was toppled and all power was given to the soviets.
Document 14: Russian Revolution: The February Revolution (March 1917) was a revolution focused around Petrograd (now Saint Petersburg), the capital of Russia at that time. In the chaos, members of the Imperial parliament (the Duma) assumed control of the country, forming the Russian Provisional Government which was heavily dominated by the interests of large capitalists and the noble aristocracy. The army leadership felt they did not have the means to suppress the revolution, resulting in Nicholas's abdication. The soviets, which were dominated by soldiers and the urban industrial working class, initially permitted the Provisional Government to rule, but insisted on a prerogative to influence the government and control various militias. The February Revolution took place in the context of heavy military setbacks during the First World War (1914 -- 18), which left much of the Russian Army in a state of mutiny.
