Perestroika (Russian: перестро́йка; ) was a political movement for reformation within the Communist Party of the Soviet Union during the 1980s (1986), widely associated with Soviet leader Mikhail Gorbachev and his glasnost (meaning "openness") policy reform. The literal meaning of perestroika is "restructuring", referring to the restructuring of the Soviet political and economic system.
Perestroika is often argued to be the cause of the dissolution of the Soviet Union, the revolutions of 1989 in Eastern Europe, and the end of the Cold War.
