Mikhail Gorbachev introduced major reforms as the leader of the Soviet Union in the 1980s that ultimately led to the end of the Cold War. His policies of perestroika and glasnost relaxed central government control of the economy and increased openness and transparency, moving the USSR away from strict Communist rule. Gorbachev's reforms transformed the Soviet system and its adversarial relationship with the West, bringing the decades-long Cold War confrontation to a peaceful conclusion.
