Mikhail Gorbachev, in full Mikhail Sergeyevich Gorbachev, (born March 2, 1931, Privolnoye, Stavropol kray, Russia, U.S.S.R.), Soviet official, general secretary of the Communist Party of the Soviet Union (CPSU) from 1985 to 1991 and president of the Soviet Union in 1990–91.
His efforts to democratize his country’s political system and decentralize its economy led to the downfall of communism and the breakup of the Soviet Union in 1991.
In part because he ended the Soviet Union’s postwar domination of eastern Europe, Gorbachev was awarded the Nobel Prize for Peace in 1990.

Early life
Gorbachev was the son of Russian peasants in Stavropol territory (kray) in southwestern Russia. He joined the Komsomol (Young Communist League) in 1946 and drove a combine harvester at a state farm in Stavropol for the next four years. He proved a promising Komsomol member, and in 1952 he entered the law school of Moscow State University and became a member of the Communist Party.
He graduated with a degree in law in 1955 and went on to hold a number of posts in the Komsomol and regular party organizations in Stavropol, rising to become first secretary of the regional party committee in 1970.
