Information:  - Siberia is an extensive geographical region, and by the broadest definition is also known as North Asia. Siberia has historically been a part of Russia since the 17th century.  - Central Asia or Middle Asia is the core region of the Asian continent and stretches from the Caspian Sea in the west to China in the east and from Afghanistan in the south to Russia in the north. It is also colloquially referred to as "the 'stans" (as the six countries generally considered to be within the region all have names ending with the Persian suffix "-stan", meaning "land of") and is within the scope of the wider Eurasian continent.  - Russia, also officially known as the Russian Empire, was a state that existed from 1721 until it was overthrown by the short-lived liberal February Revolution in 1917. One of the largest empires in world history, stretching over three continents, the Russian Empire was surpassed in landmass only by the British and Mongol empires. The rise of the Russian Empire happened in association with the decline of neighboring rival powers: the Swedish Empire, the PolishLithuanian Commonwealth, Persia and the Ottoman Empire. It played a major role in 181214 in defeating Napoleon's ambitions to control Europe, and expanded to the west and south.  - An oblast is a type of administrative division of Belarus, Bulgaria, Kazakhstan, Kyrgyzstan, Russia, Ukraine, and the now-defunct Soviet Union and Kingdom of Serbs, Croats and Slovenes. The term is analogous to "state" or "province".  - The Bolsheviks, originally also Bolshevists or Bolsheviki (derived from  "bol'shinstvo", "majority", literally meaning "one of the majority") were a faction of the Marxist Russian Social Democratic Labour Party (RSDLP) which split apart from the Menshevik faction at the Second Party Congress in 1903. The RSDLP was a revolutionary socialist political party formed in 1898 in Minsk(Belarus) to unite the various revolutionary organisations of the Russian Empire into one party.  - The All-Russian Central Executive Committee ((VTsIK)), was the highest legislative, administrative, and revising body of the Russian Soviet Federative Socialist Republic (Russian SFSR) from 1917 until 1937. Although the All-Russian Congress of Soviets had supreme authority, in periods between its sessions its powers were passed to VTsIK.  - Yakov Mikhailovich Sverdlov (known by pseudonyms "Andrei", "Mikhalych", "Max", "Smirnov", "Permyakov";  16 March 1919) was a Bolshevik party administrator and chairman of the All-Russian Central Executive Committee.  - A dictator is a ruler who wields absolute power. A state ruled by a dictator is called a dictatorship. The word originated as the title of a magistrate in the Roman Republic appointed by the Senate to rule the republic in times of emergency (see Roman dictator and "justitium").  - Baron Pyotr Nikolayevich Wrangel or Vrangel ("Baron Pyotr Nikolayevich Vrangel" April 25, 1928) was an officer in the Imperial Russian Army and later commanding general of the anti-Bolshevik White Army in Southern Russia in the later stages of the Russian Civil War. After his side lost the civil war in 1920, he left Russia and became one of the most prominent exiled White émigrés.  - The Russian Civil War was a multi-party war in the former Russian Empire immediately after the Russian Revolutions of 1917, as many factions vied to determine Russia's political future. The two largest combatant groups were the Red Army, fighting for the Bolshevik form of socialism, and the loosely allied forces known as the White Army, which included diverse interests favoring monarchism, capitalism and alternative forms of socialism, each with democratic and antidemocratic variants. In addition, rival militant socialists and nonideological Green armies fought against both the Bolsheviks and the Whites. Eight foreign nations intervened against the Red Army, notably the Allied Forces and the pro-German armies. The Red Army defeated the White Armed Forces of South Russia in Ukraine and the army led by Admiral Aleksandr Kolchak in Siberia in 1919. The remains of the White forces commanded by Pyotr Nikolayevich Wrangel were beaten in Crimea and evacuated in late 1920. Lesser battles of the war continued on the periphery for two more years, and minor skirmishes with the remnants of the White forces in the Far East continued well into 1923. Armed national resistance in Central Asia was not completely crushed until 1934. There were an estimated 7,000,000-12,000,000 casualties during the war, mostly civilians. The Russian Civil War has been described by some as the greatest national catastrophe that Europe had yet seen.  - The Green armies, Green Army (Russian: " "), or Greens (Russian: "") were armed peasant groups which fought against all governments in the Russian Civil War of 191722. They fought to protect their communities from requisitions or reprisals carried out by third parties. At times associated with the Socialist-Revolutionary Party (by far the largest grouping of the Russian Constituent Assembly elected in 1917), the Green Armies had at least tacit support throughout much of Russia. However, the Green Armies' primary base, the peasantry, were largely reluctant to wage an active campaign during the Russian Civil War. Its strength during the civil war has been measured at 40,000 men.  - An uyezd was an administrative subdivision of the Grand Duchy of Moscow, the Russian Empire, and the early Russian SFSR, which was in use from the 13th century. For most of Russian history, uyezds were a secondary-level of administrative division.  - Secret police (sometimes called political police) are intelligence services or police and law enforcement agencies which operate in secrecy. Therefore, they have little to no transparency, accountability or oversight. A secret police organization is often used beyond the law by totalitarian states to protect the political power of an individual dictator or an authoritarian (autocratic) political regime.  - Vladimir Ilyich Ulyanov, better known by the alias Lenin (  21 January 1924), was a Russian communist revolutionary, politician, and political theorist. He served as head of government of the Russian Republic from 1917 to 1918, of the Russian Soviet Federative Socialist Republic from 1918 to 1924, and of the Soviet Union from 1922 to 1924. Under his administration, Russia and then the wider Soviet Union became a one-party socialist state governed by the Russian Communist Party. Ideologically a Marxist, he developed political theories known as Leninism. Born to a wealthy middle-class family in Simbirsk, Lenin embraced revolutionary socialist politics following his brother's execution in 1887. Expelled from Kazan Imperial University for participating in protests against the Russian Empire's Tsarist regime, he devoted the following years to a law degree. He moved to Saint Petersburg in 1893 and became a senior figure in the Marxist Russian Social Democratic Labour Party (RSDLP). In 1897, he was arrested for sedition and exiled to Shushenskoye for three years, where he married Nadezhda Krupskaya. After his exile, he moved to Western Europe, where he became a prominent party theorist through his publications. In 1903, he took a key role in a RSDLP ideological split, leading the Bolshevik faction against Julius Martov's Mensheviks. Encouraging insurrection during Russia's failed Revolution of 1905, he later campaigned for the First World War to be transformed into a Europe-wide proletarian revolution, which as a Marxist he believed would cause the overthrow of capitalism and its replacement with socialism. After the 1917 February Revolution ousted the Tsar and established a Provisional Government, he returned to Russia to play a leading role in the October Revolution, in which the Bolsheviks overthrew the new regime. Lenin's government was led by the Bolsheviksnow renamed the Communist Partywith some powers initially also held by elected soviets. The new government called elections for the Constituent Assembly and...  - The Red Terror was a campaign of mass killings , torture , and systematic oppression conducted by the Bolsheviks after they seized power in Petrograd and Moscow in 1917 . Soviet historiography describes the Red Terror as having been officially announced in September 1918 by Yakov Sverdlov and ending about October 1918 . However , the term was frequently applied to political repression during the whole period of the Russian Civil War of 1918 -- 1922 . The Cheka ( the Bolshevik secret police ) conducted the mass repressions . Estimates for the total number of people killed in the Red Terror range from 50,000 to 140,000 to over one and a half million .  - The Workers' and Peasants' Red Army (: RKKA, frequently shortened in Russian to ; KA, in English: Red Army also in critical literature and folklore of that epoch - Red Horde, Army of Work) was the army and the air force of the Russian Soviet Federative Socialist Republic, and after 1922 the Union of Soviet Socialist Republics. The army was established immediately after the 1917 October Revolution (Red October or Bolshevik Revolution). The Bolsheviks raised an army to oppose the military confederations (especially the various groups collectively known as the White Army) of their adversaries during the Russian Civil War. Beginning in February 1946, the Red Army, along with the Soviet Navy, embodied the main component of the Soviet Armed Forces; taking the official name of "Soviet Army", until its dissolution in December 1991.  - Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara.  - Cheka (    "chrezvychaynaya komissiya", Emergency Committee) was the first of a succession of Soviet state security organizations. It was created on December 20, 1917, after a decree issued by Vladimir Lenin, and was subsequently led by Felix Dzerzhinsky, a Polish aristocrat turned communist. By late 1918, hundreds of Cheka committees had been created in various cities, at multiple levels including: oblast, guberniya ("Gubcheks"), raion, uyezd, and volost Chekas, with Raion and Volost Extraordinary Commissioners. After 1922, Cheka groups underwent a series of reorganizations, with the NKVD, into bodies whose members continued to be referred to as "Chekisty" (Chekists) into the late 1980s.
