Mikhail Sergeyevich Gorbachev (2 March 1931 – 30 August 2022) was a Soviet and Russian politician who was the last leader of the Soviet Union from 1985 until the country's dissolution in 1991. He served as General Secretary of the Communist Party from 1985, and additionally as head of state from 1988. Ideologically, he initially adhered to Marxism–Leninism, but moved towards social democracy by the early 1990s.
Born in Privolnoye, North Caucasus Krai, into a peasant family of Russian and Ukrainian heritage, Gorbachev grew up under the rule of Joseph Stalin. In his youth, Gorbachev operated combine harvesters on a collective farm, before joining the Communist Party, which then governed the Soviet Union as a one-party state. Studying at Moscow State University, he married fellow student Raisa Titarenko in 1953 and received his law degree in 1955. Moving to Stavropol, he worked for the Komsomol youth organization and, after Stalin's death, became a keen proponent of the de-Stalinization reforms of Soviet leader Nikita Khrushchev.
