Gorbachev's policies refer to the reforms introduced by Mikhail Gorbachev, the last leader of the Soviet Union, aimed at revitalizing the Soviet economy and society in the 1980s. These policies, particularly 'glasnost' (openness) and 'perestroika' (restructuring), played a crucial role in the context of the Cold War's conclusion by promoting transparency, reducing censorship, and encouraging economic reform, ultimately leading to significant political changes within the Soviet Union and Eastern Europe.
