Mikhail Gorbachev was the last General Secretary of the Communist Party of the Soviet Union and the first and only President of the Soviet Union, serving from 1985 until its dissolution in 1991. He is best known for his policies of glasnost (openness) and perestroika (restructuring), which aimed to reform the Soviet political and economic systems, ultimately leading to significant changes in Eastern Europe and the rise of nationalist movements within the Soviet Union.
