Mikhail Gorbachev implemented reforms in the Soviet Union known as glasnost (openness) and perestroika (restructuring) in an attempt to save communism and the Soviet system. This included decentralizing the economy, reducing arms spending, and allowing more freedom of speech. However, the reforms were too slow and failed to address economic problems. Gorbachev's relaxation of control contributed to the collapse of other Eastern bloc communist governments and the ultimate dissolution of the Soviet Union in 1991, bringing an end to the Cold War.
