Question: Who led a successful Marxist revolution in the country which would eventually invade its southern neighbor where Mapado was filmed?

The war began on 25 June 1950 when North Korea invaded South Korea following a series of clashes along the border. The United Nations, with the United States as the principal force, came to the aid of South Korea. The Korean War (in South Korean Hangul: 한국전쟁; Hanja: 韓國戰爭; RR: Hanguk Jeonjaeng, ``Korean War ''; in North Korean Chosŏn'gŭl: 조국해방전쟁; Hancha: 祖國解放戰爭; MR: Choguk haebang chǒnjaeng,`` Fatherland Liberation War''; 25 June 1950 -- 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States). China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North. <SEP> She had joined the Bolsheviks in 1916. Alexandra Kim, a Korean who lived in Russia, is sometimes credited as the first Korean communist. In 1917, Vladimir Lenin sent her to Siberia to mobilize Koreans there against the counter-revolutionary forces and the Allied Expeditionary Forces. In Khabarovsk Kim was in charge of external affairs at the Far - Eastern Department of the Party. There she met with Yi Dong - Wi, Kim Rip and other Korean independence fighters. Together they founded the Korean People's Socialist Party, the first Korean communist party on June 28, 1918. <SEP> "Do" can either mean "province" or "island" in Korean. "Seom" means island in the Korean language as well, although "do" is a Sino-Korean word used in name compound words, but "seom" can stand alone. Filming for "Mapado" did not take place on an island, but in Dongbaek village in Yeonggwang County, South Korea. <SEP> at the start of the 20th century, the russian empire was an autocracy controlled by the tsar, with millions of the country's largely agrarian population living in abject poverty, and the anti-communist historian robert service noted, ``poverty and oppression constituted the best soil for marxism to grow in ''. the man responsible for largely introducing the ideology into the country was georgi plekhanov, although the movement itself was largely organised by a man known as vladimir lenin, who had for a time been exiled to a prison camp in siberia by the tsarist government for his beliefs. a marxist group known as the russian social democratic labour party was formed in the country, although it soon divided into two main factions: the bolsheviks led by lenin and the mensheviks led by julius martov. in 1905, there was a revolution against the tsar's rule, in which workers' councils known as`` soviets'' were formed in many parts of the country and the tsar was forced to implement democratic reform, introducing an elected government, the duma. <SEP> born to a moderately prosperous middle-class family in simbirsk, lenin embraced revolutionary socialist politics following his brother's 1887 execution. expelled from kazan imperial university for participating in protests against the russian empire's tsarist government, he devoted the following years to a law degree. he moved to saint petersburg in 1893 and became a senior marxist activist. 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 theorist in the marxist russian social democratic labour party (rsdlp). 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.
